[0018]
In the present specification, "voice" includes "sound", and is not limited to human voice and the
like, but broadly includes the sound itself. For example, it includes sounds played by a musical
instrument. It also includes inaudible sounds such as ultrasound. Further, “audio data” is
digital data obtained by converting (sampling, encoding, and the like) analog audio, and is data
which can be read and operated by a computer.
[0019]
As a modification of the configuration of the film speaker 100, the film speaker 100 may include
only the speaker card 106. The functions of the control device 102 and the amplifier 104 may be
provided to an external device (for example, an amplifier stand or the like). In this case, the user
may insert and connect the speaker card 106 to an external device, and the speaker card 106
may output audio based on the audio signal output from the external device.
[0020]
As another variation, the film speaker 100 may include the control device 102 and the speaker
card 106. The function of the amplifier 104 may be provided to an external device (for example,
an amplifier stand or the like). Also in this case, the user inserts the film speaker 100 into an
external device and connects the film speaker 100, and the film speaker 100 outputs an audio
signal based on audio data held in the built-in memory to the external device, and the amplified
audio signal is externally output. It may be acquired from the device and a voice may be output.
[0021]
Hereinafter, an electroacoustic transducer utilizing the film speaker 100 (speaker card 106) of
FIG. 1 is proposed. 2 and 3 show an example of use of the electroacoustic transducer 110
according to the embodiment. The electro-acoustic transducer 110 is configured in a thin film
shape and has high flexibility, like the film speaker of Non-Patent Document 1. The electroacoustic transducer 110 may be formed of a material having a certain degree of rigidity, as long
14-04-2019

as the material has a change in appearance (that is, the appearance shape) due to the user's
action of breaking or folding.
[0022]
FIG. 2 shows an example of applying the electroacoustic transducer 110 to a leaflet (poster) for
making a concert known. The leaflet 120 includes a guide section 122 in which a concert guide
is described, and a ticket section 124 which is an entrance ticket for the concert. The
electroacoustic transducer 110 is provided across the guiding unit 122 and the ticket unit 124.
The user breaks the leaflet 120 (i.e., the electroacoustic transducer 110), and separates the guide
part 122 and the ticket part 124. The electro-acoustic transducer 110 detects a change in its
shape caused by the user breaking the leaflet 120, and audibly outputs a pre-stored message (for
example, an idle voice message).
[0023]
FIG. 3 shows an example of applying the electroacoustic transducer 110 to origami. Here, the
whole of the origami 126 is formed by the electroacoustic transducer 110. The user folds the

change in its shape caused by the user folding the origami 126, and audibly outputs a pre-stored
message (for example, a message from a family member).

electro-acoustic transducer 110 itself. As a result, a new form of human-to-human
communication using speech is realized, and a novel entertainment experience using speech is
provided to the user.

Hereinafter, as a first embodiment, an electro-acoustic transducer 110 is proposed which
executes data processing related to voice according to the user's action "break". In addition, as a
second embodiment, an electro-acoustic transducer 110 is proposed which executes data
processing relating to voice in accordance with the user's action "break". Further, as a third
embodiment, a configuration is proposed in which an external device detects a change in shape
of the electroacoustic transducer 110.
[0026]

electroacoustic transducer 110 of the first embodiment is a film speaker triggered by being
broken. As described later, the electro-acoustic transducer 110 according to the first embodiment
performs audio processing even when pieces of the separated electro-acoustic transducer 110
are joined.
[0027]
FIG. 4 is a block diagram showing a functional configuration of the electro-acoustic transducer
110 of the first embodiment. The electroacoustic transducer 110 includes a vibrating body 10, a
power supply unit 20, a storage unit 30, a control unit 40, and a communication unit 50.
Although not shown in FIG. 4, the electroacoustic transducer 110 may further include an
amplifier unit that amplifies the audio signal. The amplifier unit may amplify an audio signal to
be output to the vibrating body 10 or an audio signal input from the oscillating body 10 as
necessary.
[0028]
Each block described in the block diagram of the present specification can be realized by
hardware as an element or electronic circuit such as a CPU or memory of a computer, a
mechanical device or the like by software as a computer program or the like However, here, the
functional block realized by those cooperation is drawn. Therefore, it is understood by those
skilled in the art that these functional blocks can be realized in various forms by a combination of
hardware and software.

[0029]
FIG. 5 shows an example of the hardware configuration of the electroacoustic transducer 110. As
shown in FIG. The piezoelectric element 112 of FIG. 5 corresponds to the vibrator 10 of FIG. 4.
Electric double layer capacitor 114 of FIG. 5 corresponds to power storage unit 24 of FIG. 4. The
control circuit 116 of FIG. 5 corresponds to the control unit 40 of FIG. The transmission /
reception circuit 118 of FIG. 5 corresponds to the communication unit 50 of FIG. The storage
unit 30 of FIG. 4 may be incorporated in the control circuit 116 of FIG. 5 as a semiconductor
memory.
[0030]
Returning to FIG. 4, the vibrating body 10 corresponds to the film speaker of Non-Patent
Document 1, and is configured of a piezoelectric film (piezoelectric element, micro piezo, etc.)
formed in a thin film shape. Typically, it functions as a diaphragm. The vibrating body 10
converts the audio signal input from the control unit 40 into physical vibration, that is, vibrates
in a mode according to the audio signal to generate a sound indicated by the audio signal. The
vibrating body 10 also functions as a diaphragm of a microphone. That is, it converts
surrounding sound (air vibration) into an electrical signal, and outputs a sound signal based on
the surrounding sound to the control unit 40.
[0031]
The vibrating body 10 also functions as a power generation unit that generates power according
to the shape change. When the user breaks or breaks the vibrating body 10 to change the shape
of the vibrating body 10, a voltage is generated according to the form of the shape change of the
vibrating body 10 (for example, the pressure causing the shape change) by the piezoelectric
effect. . The generated voltage is provided to the power supply unit 20 and the control unit 40.
[0032]
Alternatively, the electroacoustic transducer 110 may separately include the vibrator 10 and the
14-04-2019
9
power generation unit. In this case, the power generation unit may be realized by a known
technology other than the piezoelectric element. For example, the power generation unit may
generate power by the heat of the surface of the power generation unit, or may generate power
by the ion concentration difference. Alternatively, solar power may be generated using a silicon
solar cell or the like, or power may be generated by an enzyme reaction (for example, the power
generation unit is immersed in juice).
[0033]
The vibrating body 10 is provided on the surface of the electroacoustic transducer 110 formed in
a film shape, and occupies at least a part of the surface of the electroacoustic transducer 110.
The vibrating body 10 may be provided over the entire surface of the electroacoustic transducer
110. The change in shape of the vibrating body 10 in the description of the specification may
also be referred to as the change in shape of the electroacoustic transducer 110.
[0034]
The power supply unit 20 supplies power to the storage unit 30, the control unit 40, and the
communication unit 50. Power supply unit 20 includes a rectification circuit 22, a storage unit
24, and a constant voltage circuit 26. The rectifying circuit 22 is a circuit that rectifies the
voltage generated by the vibrating body 10. The rectifier circuit 22 may be configured by a diode
or a diode bridge.
[0035]
Power storage unit 24 stores the DC voltage output from rectifier circuit 22. The storage unit 24
may be configured of, for example, an electric double layer capacitor, a lithium ion capacitor, a
polyacene organic semiconductor capacitor, a nanogate capacitor, a ceramic capacitor, a film
capacitor, an aluminum electrolytic capacitor, a tantalum capacitor, or the like.
[0036]
The constant voltage circuit 26 converts the output voltage from the storage unit 24 into a
14-04-2019
10
predetermined voltage, and stabilizes the output voltage from the power supply unit 20. As
described above, in the electroacoustic transducer 110, the electricity generated by the vibrating
body 10 is stored, and the stored electricity is provided to each functional block. As a result, it is
possible to eliminate the need for a power source such as a battery for operating each functional
block.
[0037]
However, since the amount of power generation of the vibrating body 10 is relatively small, the
operation time of the control unit or the like may be limited as appropriate. For example, the time
for audio recording and reproduction in the control unit 40 may be limited to several seconds to
several tens of seconds. As a modification, the power supply unit 20 may be realized by a power
supply external to the electroacoustic transducer 110 or another known technique such as a
battery.
[0038]
The communication unit 50 executes communication processing with an external device, and
typically performs wireless communication. As a wireless communication system, ANT standard
("ANT" is a trademark or registered trademark), Z-Wave standard ("Z-Wave" is a trademark or
registered trademark), ZigBee standard ("ZigBee") A trademark or registered trademark, BLE
(Bluetooth Low Energy) ("Bluetooth" is a trademark or registered trademark), Wifi (trademark or
registered trademark), etc. may be adopted, and an appropriate method is applied according to
the characteristics of each standard. You may
[0039]
The external device that is the opposite device of the communication by the communication unit
50 may be an information processing device installed at a position near the electroacoustic
transducer 110. For example, it may be a PC, a stationary game machine, a portable game
machine, a smartphone or the like. Also, upon receiving an audio data provision request from the
electroacoustic transducer 110, the external device further downloads predetermined audio data
from an external server via the Internet, and transmits the audio data to the electroacoustic
transducer 110. It is also good.
14-04-2019

[0040]
The storage unit 30 provides a storage area for storing various data for data processing by the
control unit 40. For example, it may be realized by a nonvolatile semiconductor memory device.
The storage unit 30 includes a reference holding unit 32 and an audio data holding unit 34. The
audio data holding unit 34 holds audio data to be reproduced (in other words, an external output
target) in the electro-acoustic transducer 110.
[0041]
The reference holding unit 32 is also referred to as reference data (hereinafter, referred to as
“shape change detection reference”) for detecting that an appearance change in the shape of
the vibration member 10 occurs when the user breaks the vibration member 10. Hold). The
reference holding unit 32 is also referred to as reference data (hereinafter referred to as “voice
output condition”) as a condition under which the electroacoustic transducer 110 outputs a
voice. Hold).
[0042]
The shape change detection reference is data defining electrical changes generated in the
vibrating body 10 due to the shape change of the vibrating body 10. Also, it is data for
comparison with the electrical change of the vibrating body 10 actually detected by the control
unit 40. The shape change detection reference may be data indicating a waveform pattern of a
voltage generated as the shape of the vibrator 10 changes. The data may be data indicating the
level of the waveform or the time interval between the waveforms, that is, various information
obtained based on the waveform of the voltage. Further, when shape change is detected using
RFID (Radio Frequency IDentifier) as described later, the shape change detection reference is the
response state of the RF tag whose shape change is to be detected, in other words, the signal
from the RF tag. It may be data that defines the reception state.
[0043]
The shape change detection standard is data for detecting the fact that the shape change at a
14-04-2019
12
level recognizable by human eyes has occurred in the vibrator 10. Therefore, it is desirable to
exclude the information of the electrical change in the case where the vibrating body 10 vibrates
weakly due to a surrounding sound or the like (for example, a human voice) from the shape
change detection reference.
[0044]
The voice output condition may be that an apparent shape change is detected in the vibrating
body 10, and the shape change detection unit 42 described later may be a fact that the vibrating
body 10 is broken. . For example, the audio output condition may be data that determines that
the change in the electrical signal output from the vibrator 10 matches the shape change
detection reference. Specific examples of the shape change detection reference and the voice
output condition will be described later.
[0045]
The control unit 40 executes data processing related to voice. The control unit 40 includes a
shape change detection unit 42, an audio output control unit 44, an audio recording unit 46, and
a D / A conversion unit 48. The D / A conversion unit 48 performs digital-to-analog conversion
processing. For example, digital audio data acquired from the audio data holding unit 34 is
converted into an analog audio signal. Further, it converts an audio signal based on the ambient
sound input from the vibrator 10 into audio data.
[0046]
The shape change detection unit 42 detects that the shape change on the appearance of the
vibrator 10 has occurred due to the action of the user. Specifically, when a change in the shape
of the vibrating body 10 occurs due to the user breaking the vibrating body 10, the shape change
detection unit 42 generates an electrical change that accompanies an act of breaking the fact.
Detect based on. Furthermore, when the electrical change in the vibrating body 10 is detected,
the shape change detection unit 42 collates the detected electrical change with the shape change
detection reference (reference for breaking detection), and both are matched. It is determined
that the vibrator 10 has been broken. The shape change detection unit 42 is also referred to as a
broken position of the vibrating body 10 (hereinafter referred to as a “break position”). ) Is
also detected.
14-04-2019
13
[0047]
The terms "matching", "matching" and the like in the present specification include perfect match,
near match, and approximation. That is, the terms "matching", "matching" and the like in the
present specification may allow some difference other than the exact match. For example, when
the difference between one of the comparison object and the other is within a predetermined
tolerance, the two may be regarded as “matching” or “matching”. An appropriate value may
be determined by the experience or knowledge of the developer of the electroacoustic transducer
110, an experiment using the electroacoustic transducer 110, or the like.
[0048]
In addition, when the user causes two or more vibrators 10 to be joined together and the shape
of the vibrator 10 is changed, the shape change detection unit 42 electrically generates the fact
of joining the facts. Detect based on changes. The shape change detection unit 42 collates the
detected electric change with the shape change detection reference (reference for detection of
bonding) when the electric change in the vibrating body 10 is detected, and when both are
matched, It is determined that another vibrating body 10 is joined to the vibrating body 10. Note
that "joining" can be said to be "merging".
[0049]
The audio output control unit 44 decodes the audio data stored in the audio data storage unit 34
when the audio output condition of the reference storage unit 32 is satisfied, and outputs the
audio signal of the decoding result to the vibrator 10. Thereby, the voice based on the voice data
is output through the vibrating body 10. It may be defined that a change in shape (for example,
breaking) of the vibrating body 10 is detected as an audio output condition. In this case, the voice
output control unit 44 may output voice immediately when the shape change detection unit 42
detects a change in shape (for example, breakage) of the vibrating body 10.
[0050]
14-04-2019
14
The voice recording unit 46 encodes the voice signal input from the vibrator 10 and stores voice
data of the encoding result in the voice data holding unit 34. Further, the voice recording unit 46
acquires the voice data received by the communication unit 50 and stores the voice data in the
voice data holding unit 34.
[0051]
Next, the fact that the vibrator 10 has broken and the method of detecting the broken position
will be described in detail. Although five methods are illustrated below, other known methods
may be used. Also, a plurality of detection methods may be combined as appropriate.
[0052]
Method 1. Use of RFID: FIGS. 6 (a) and 6 (b) are conceptual diagrams of a shape change detection
method using RFID. In this example, a plurality of RF tags 130 are disposed on the vibrator 10.
The shape change detection unit 42 includes an RF reader, and transmits a response request to
each RF tag 130 periodically (for example, at intervals of 300 milliseconds). FIG. 6A shows the
initial state of the vibrating body 10, that is, the state before the user breaks the vibrating body
10. The shape change detection unit 42 does not detect that the vibrator 10 has been broken
because it receives response signals from all the RF tags 130. In other words, it is determined
that the vibrating body 10 is not broken. The response signal from the RF tag 130 can also be
referred to as a keep-alive signal.
[0053]
FIG. 6B shows a state after the user has broken the vibrating body 10. When the user breaks the
vibrating body 10, the shape change detection unit 42 does not receive the response signal from
the RF tag 130 disposed on the vibrating body 10 separated from the electroacoustic transducer
110. The shape change detection unit 42 determines that the shape change detection criterion is
satisfied when the response signal from at least a part of the plurality of RF tags 130 is not
received, and the vibrator 10 is broken. Detect the facts.
[0054]
14-04-2019
15
Communication between the RF reader (shape change detection unit 42) and the RF tag 130 may
be realized by known near field communication such as NFC (Near Field Communication), and the
communicable range may be about 10 cm. . Moreover, although the example of radio | wireless
communication was given in FIG. 6 (a) (b), also in wire communication, since a communication
line is cut | disconnected, a fracture | rupture detection is possible similarly.
[0055]
Further, in FIGS. 6A and 6B, many RF tags 130 are disposed on the entire surface of the vibrating
body 10, but the arrangement mode of the RF tags 130 is not limited to this. When the position
where the user should break the vibrating body 10 is predetermined, one RF tag 130 is disposed
in the area to be broken and separated, and according to the presence or absence of the response
signal from the one RF tag 130, It may be determined whether or not the vibrator 10 has been
broken. For example, as shown in FIG. 2A, when the cut position of the ticket is predetermined,
the shape change detection unit 42 may be provided in the ticket unit 124 and one RF tag 130
may be provided in the guide unit 122.
[0056]
In addition, the storage unit 30 may store tag information in which ID information of each of the
plurality of RF tags 130 is associated with position information of each RF tag 130 disposed on
the vibrator 10. The response from each RF tag 130 may include the ID information of each RF
tag 130. The shape change detection unit 42 detects the ID of the RF tag 130 included in the
received response signal, and the RF tag 130 which has not received the response signal for a
predetermined time (for example, one second) or longer (hereinafter also referred to as “nonresponse tag”) . ) May be detected. The shape change detection unit 42 may identify the
position of the non-response tag by referring to the tag information, and determine that the
region of the vibrator 10 including the non-response tag is broken. As a result, the shape change
detection unit 42 can identify the broken position (broken region) of the vibrating body 10.
[0057]
Method 2. Measurement of electrical resistance: Conductive carbon is applied to the surface of
the vibrating body 10. The reference holding unit 32 holds, as a shape change detection
14-04-2019
16
reference, the value of the amount of electrical resistance of the vibrating body 10 or the change
pattern of the amount of electrical resistance (in other words, “transition pattern”) when the
vibrating body 10 is broken. The shape change detection unit 42 constantly or periodically
measures the amount of electrical resistance of the vibrating body 10. The shape change
detection unit 42 detects the fact that the vibrator 10 is broken when the value of the amount of
electric resistance of the vibrator 10 or the change pattern of the amount of electric resistance
matches the shape change detection reference.
[0058]
Method 3. Measurement of electromotive force: The shape change detection unit 42 detects the
fact that the vibrating body 10 is broken based on the pattern of the power generated by the
piezoelectric effect accompanying the breaking of the vibrating body 10. Specifically, the shape
change detection unit 42 measures a voltage output from the vibrating body 10, and also refers
to a waveform pattern of voltage (hereinafter referred to as "power generation information")
indicating transition of the voltage. Generate). The reference holding unit 32 holds a waveform
pattern of the voltage output from the vibrating body 10 when the vibrating body 10 is broken,
as a shape change detection reference. The shape change detection unit 42 detects that the
vibrator 10 has been broken when the generated power generation information matches the
shape change detection reference. The power generation information and the shape change
detection reference may be data indicating the level of the waveform or the time interval
between the waveforms, that is, various information obtained based on the waveform of the
voltage.
[0059]
Further, the shape change detection reference of the reference holding unit 32 may hold a
plurality of types of waveform patterns when various positions (areas) of the vibrating body 10
are broken, which are determined by prior experiments or the like. Specifically, a plurality of
types of waveform patterns may be stored in association with identification information of a
plurality of broken positions. The shape change detection unit 42 may specify a waveform
pattern that matches the power generation information from among a plurality of types of
waveform patterns as a shape change detection reference, and specify a break position
associated with the specified waveform pattern. As a result, the shape change detection unit 42
can identify the broken position (broken region) of the vibrating body 10.

[0060]
Method 4. Measurement of power generation amount: When the power generation unit of the
electroacoustic transducer 110 performs solar power generation, the shape change detection
unit 42 measures the power generation amount (for example, voltage or current) output from the
power generation unit. The reference holding unit 32 holds the value of the power generation
amount of the power generation unit or the transition pattern of the power generation amount as
the shape change detection reference. The shape change detection unit 42 detects the fact that
the vibrating body 10 is broken when the value of the power generation amount of the power
generation unit or the transition pattern of the power generation amount matches the shape
change detection reference.
[0061]
Method 5. Determining the Electrical Conduction State: FIG. 7 shows a circuit configuration for
shape change detection. Here, the cutting position 140 in the vibrator 10 of the electroacoustic
transducer 110 is predetermined. A conducting wire (electric wire) is disposed inside the
vibrating body 10, and a circuit 142 is configured across the cutting position 140. In other
words, the circuit 142 is configured over a plurality of areas separated by the user's breaking
action. The shape change detection unit 42 determines the presence or absence of conduction
based on the voltage information measured by the voltmeter 144. Then, when there is no
conduction, it is determined that the shape change detection criterion is satisfied, and the fact
that the vibrating body 10 is broken is detected. The switch 146 may be turned on at a
predetermined conduction determination timing (for example, every 300 milliseconds), or may
be always on.
[0062]
Further, a plurality of conducting wires may be arranged in a grid shape inside the vibrating
body 10, and a plurality of circuits may be configured using each of the plurality of conducting
wires. The shape change detection unit 42 determines whether or not each circuit is conductive,
and when it detects that there is no conduction in a certain circuit, it detects that the lead wire
used in that circuit is disconnected, and the vibrator 10 is broken. Detect the facts. In addition,
the storage unit 30 may hold identification information of each lead and an arrangement position
of each lead in the vibrator 10 in association with each other. The shape change detection unit
42 may specify the break position based on the arrangement position of the cut wire. As a result,
14-04-2019
18
the shape change detection unit 42 can identify the broken position (broken region) of the
vibrating body 10.
[0063]
Next, a method of detecting the fact that a plurality of vibrators 10 are joined (merged) will be
described in detail. Although two methods are illustrated below, other known methods may be
used. Also, a plurality of detection methods may be combined as appropriate.
[0064]
Method 1. Use of RFID: As shown in FIGS. 6 (a) and 6 (b), a plurality of RF tags 130 are disposed
on the vibrating body 10. The storage unit 30 holds in advance the ID information of the RF tag
130 disposed on the vibrator 10 to be joined. The shape change detection unit 42 specifies the
ID of the RF tag 130 contained in the received response signal, and the shape change is detected
when the specified ID matches the ID of the RF tag 130 disposed on the vibrator 10 to be joined.
It is determined that the reference is satisfied, and it is detected that the plurality of vibrators 10
are joined.
[0065]
Further, as shown in FIG. 6A, the storage unit 30 may hold ID information of all the RF tags 130
disposed on the vibrator 10 before cutting. When this vibrating body 10 is broken as shown in
FIG. 6 (b) and then joined in the state of FIG. 6 (a), the shape change detection unit 42 determines
all the IDs stored in the storage unit 30. It may be determined that the shape change detection
criterion is satisfied by receiving a response signal to indicate that the vibrator 10 that has been
separated once is joined again. As a result, the shape change detection unit 42 can detect that the
vibrator 10 originally integrated is broken and that fragments of the broken vibrator 10 are
combined.
[0066]
When only the fact of bonding is detected, the number of received response signals, in other
14-04-2019
19
words, the number of IDs of the RF tags 130 specified by the received response signals, is more
than that at the time of the previous confirmation. It may be detected that the vibrating body 10
of is joined. For example, the case where the number of receptions of the response signal
increases from 0 to 1 corresponds. In this case, one RF tag 130 may be disposed only on the
vibrator 10 joined to the electroacoustic transducer 110 (the vibrator 10) provided with the
shape change detection unit 42.
[0067]
Method 2. Determine the continuity of electricity: As shown in FIG. 7, when the cutting position
140 in the vibrating body 10 of the electroacoustic transducer 110 is predetermined, the circuit
142 straddles the cutting position 140 inside the vibrating body 10. Provide The shape change
detection unit 42 determines the presence or absence of conduction based on the voltage
information measured by the voltmeter 144, and determines that the shape change detection
criterion is satisfied when there is a change from no conduction to existence, and a plurality of
vibrators It detects that 10 is joined.
[0068]
As another method, the reference holding unit 32 may hold, as a shape change detection
reference, the amount of electric resistance and the amount of power generation when a plurality
of vibrators 10 are joined. The shape change detection unit 42 compares the amount of electric
resistance and the amount of power generation actually measured in the vibrator 10 with the
shape change detection reference, and detects that the plurality of vibrators 10 are joined when
the two match. May be
[0069]
The operation of the electroacoustic transducer 110 according to the first embodiment having
the above configuration will be described. Here, it is assumed that the entire surface of the
electroacoustic transducer 110 is configured as the vibrator 10 (i.e., a film speaker). The change
in shape of the vibrator 10 can be read as the change in shape of the electroacoustic transducer
110 (i.e., the film speaker).
14-04-2019
20
[0070]
FIG. 8 is a flowchart showing a first operation example of the electroacoustic transducer 110.
The shape change detection unit 42 monitors an electrical change of a predetermined monitoring
target item of the vibrator 10 (S10). The monitoring target item is an information item defined by
the shape change detection standard, and changes in the reception state of the response signal
(FIGS. 6A and 6B), changes in the amount of electric resistance, changes in electromotive force,
and power generation Or at least one of changes in electrical conduction state. When the user
breaks the vibrating body 10, an electrical change occurs in the vibrating body 10.
[0071]
The shape change detection unit 42 detects an electrical change of the item to be monitored (Y in
S12), and when the mode of the change matches the shape change detection criteria (Y in S14),
the shape change occurs in the vibrating body 10 Detected facts (S16). In the first embodiment,
the fact that the vibrating body 10 is broken is detected. The shape change detection unit 42
notifies the voice output control unit 44 of information indicating the fact. If the electrical change
of the monitored item is not detected (N in S12) or the detected electrical change is inconsistent
with the shape change detection reference (N in S14), S16 is skipped.
[0072]
When the voice output condition is satisfied (Y in S18), the voice output control unit 44 causes
the voice data holding unit 34 to output a voice based on the voice data stored in advance
through the vibrator 10 (S20). For example, even if digital audio data is passed to the D / A
converter 48 and converted into an analog audio signal, and the audio signal is output to the
oscillator 10, the oscillator 10 is vibrated to generate sound. Good. If the voice output condition
is not satisfied (N in S18), S20 is skipped, and the process of FIG.
[0073]
The electro-acoustic transducer 110 periodically repeats the operations shown in the present
drawing and the subsequent flowcharts, and repeatedly executes, for example, each time a
predetermined time (for example, 300 milliseconds) elapses. However, the electro-acoustic
14-04-2019
21
transducer 110 may stop the repetition of the operation shown in the flowchart when the sound
output process of S20 is performed a predetermined number of times (for example, once).
Further, the determination process (for example, S12 and S14) of the presence or absence of the
shape change detection standard and the determination process (for example, S18) of the
presence or absence of the voice output condition may be executed in parallel.
[0074]
The sound output condition may be that the fact that the vibrator 10 has been broken is detected
by the shape change detection unit 42. That is, the voice output control unit 44 may output voice
immediately upon detection of breakage of the vibrating body 10. In this case, the determination
of S18 is omitted, and the configuration is the same as that of S20. As a product to which the
electro-acoustic transducer 110 of this aspect is applied, a leaflet which is torn when broken as
shown in FIG. 2, an advertisement, a poster, etc. can be considered. In addition, wrapping paper
that outputs a predetermined voice message such as expiration date or the like triggered by a
break or a seal that outputs a warning voice message triggered by a break may be considered.
[0075]
Also, the audio output condition may be connected to an amplifier. In this case, when the user
breaks the electroacoustic transducer 110 and connects the fragments to the amplifier, the
fragments output a sound. For example, the audio output control unit 44 detects the fact that the
electro-acoustic transducer 110 is connected to the amplifier based on a predetermined signal
input from the amplifier at the time of amplifier connection, and causes the detection to output
voice. It is also good.
[0076]
Further, the audio data holding unit 34 may store plural types of audio data. The reference
holding unit 32 outputs, as voice output conditions, voice data to be output for each of a plurality
of tear position candidates and “tearing position candidate” which is information indicating a
position / region which may be broken in the vibrator 10. You may match and memorize | store
the information which shows the kind of. The shape change detection unit 42 may detect the
break position of the vibrating body 10. The voice output control unit 44 may reproduce voice
data associated with the torn position candidate that matches the detected torn position.
14-04-2019
22
According to this aspect, for example, it is possible to realize the electroacoustic transducer 110
in which the music played at the broken place is different. In addition, the amount of tear
position candidates can be suppressed by predetermining the break position in the vibrating
body 10, that is, the position where the user should break the vibrating body 10.
[0077]
By the way, if the breaking position is different, the shape of the vibrating body 10 as a result of
being broken will also be different. Therefore, switching the sound to be output according to the
torn position can also be said to switch the sound to be output according to the shape of the
broken vibration body 10. That is, as a result of the vibration body 10 being broken, the sound
output control unit 44 outputs the first sound when the vibration body 10 changes to the first
shape, and the vibration body 10 changes to the second shape In some cases, a second voice may
be output.
[0078]
Further, the shape change detection reference may be a reference for detecting bonding of a
plurality of vibrators 10, and for example, even if a pattern of electrical change accompanying
bonding of a plurality of vibrators 10 is determined Good. The voice output condition may be
that a junction of a plurality of vibrators 10 is detected. In this case, the voice output control unit
44 reproduces voice data immediately in response to the plurality of vibrators 10 being joined.
May be The electro-acoustic transducer 110 of this aspect outputs voice when a user joins the
fragment (electro-acoustic transducer 110) originally cut off, and can be applied to various toys
and communication tools.
[0079]
Further, the audio output condition may be that a predetermined time has elapsed since the
detection of the shape change. In this case, the voice output control unit 44 may start time
measurement by the timer triggered by the shape change detection by the shape change
detection unit 42. The voice output control unit 44 may reproduce voice data when the elapsed
time from the shape change detection by the shape change detection unit 42 matches the time
determined by the voice output condition. According to this aspect, it is possible to realize, for
example, a memo pad or a tag for outputting a message by voice when a predetermined time,
14-04-2019
23
such as three minutes or one hour, has passed after separation from the mount. A combination
with the configuration described later for recording surrounding voice at the time of shape
change is also effective.
[0080]
FIG. 9 is a flowchart showing a second operation example of the electroacoustic transducer 110.
The processes of S30 to S36 and S40 to S42 in this figure are the same as S10 to S16 and S18 to
S20 in FIG. In S36, when detecting that the vibrating body 10 is broken, the shape change
detection unit 42 notifies the voice recording unit 46 to that effect. The voice recording unit 46
transmits a voice data provision request to a nearby information processing apparatus. Then, the
voice data transmitted from the device is acquired and stored in the voice data holding unit 34
(S38). In the case of N at S32 or N at S34, S36 and S38 are skipped.
[0081]
In the second operation example of FIG. 9, the electro-acoustic transducer 110 acquires audio
data to be reproduced from an external device at the time of shape change detection. Therefore,
the content of the sound output from the electroacoustic transducer 110 can be easily changed
or updated by changing or updating the sound data provided from the external device (for
example, the sound data held by the external device) as necessary. be able to. For example, the
electro-acoustic transducer 110 can output a suitable sound according to the situation when the
electro-acoustic transducer 110 is broken, the fashion in the society, and the convenience of the
business.
[0082]
The shape change detection criterion may be that the first position of the vibrating body 10 is
broken, and the sound output condition may be that the second position of the vibrating body 10
different from the first position is broken. In this case, when the shape change detection unit 42
detects that the first position of the vibrating body 10 is broken, the voice recording unit 46
acquires and records voice data. Thereafter, when the shape change detection unit 42 detects
that the second position of the vibrating body 10 is broken, the sound output control unit 44
reproduces and outputs the sound data acquired earlier. The user can control the sound
processing aspect of the electroacoustic transducer 110 by the position where the vibrating body
14-04-2019
24
10 is broken.
[0083]
In addition, in S38 of FIG. 9, in place of acquiring audio data from an external device,
surrounding audio may be recorded. Specifically, the vibrator 10 may output an audio signal
indicating the surrounding sound to the control unit 40. The D / A conversion unit 48 may
encode the input audio signal to generate audio data, and the audio recording unit 46 may store
the generated audio data in the audio data storage unit 34. According to this aspect, it is possible
to record the surrounding sound when the vibrating body 10 is broken and reproduce the sound
when the sound output condition is satisfied.
[0084]
Also, when the first position of the vibrating body 10 is broken, it is assumed that the shape
change detection criteria are satisfied, and the surrounding voice (here, a message generated by
the user who broke the vibrating body 10) is recorded. It is also good. In addition, when the
second position of the vibrating body 10 is broken, it may be possible to output, from the
vibrating body 10, a voice recorded in advance, assuming that the audio output condition is
satisfied. According to this aspect, the user A breaks part of the electroacoustic transducer 110
as a message card to store a voice message, and the user B breaks part of the electroacoustic
transducer 110 to listen to the voice message. Communication can be realized.
[0085]
As a modification of the above-mentioned message card, voice output conditions may be a
standard for detecting junction of a plurality of vibrators 10, for example, a pattern of electric
change accompanying joining of a plurality of vibrators 10 May be defined. The sound output
control unit 44 reproduces sound data in response to the shape change detection unit 42
detecting the bonding of the plurality of vibrators 10.
[0086]
14-04-2019
25
According to this aspect, after breaking one vibration body 10 and recording surrounding sounds
or sounds provided from an external device, the previously recorded sound can be recorded by
joining pieces of the vibration body 10. Communication can be realized in the form of
reproduction. Bonds can not be detected with so-called fake fragments other than the original
fragments. Therefore, the electro-acoustic transducer 110 can be used as a slogan of people who
own the original fragments, in other words, as a symbol among a plurality of people.
[0087]
Second Embodiment (hereinafter, referred to as “second embodiment”) The electro-acoustic
transducer 110 of the second embodiment is a film speaker that is triggered by being broken. In
the second embodiment, the action of the user “folds” includes various actions related to
changing the shape of the vibrating body 10 and folding. For example, the action of stretching
the vibrating body 10 originally folded and the action of rolling the vibrating body 10 are
included.
[0088]
The functional configuration of the electroacoustic transducer 110 of the second embodiment is
the same as the configuration of the first embodiment shown in FIG. Hereinafter, the description
overlapping with the first embodiment will be appropriately omitted. The reference holding unit
32 holds a shape change detection reference for detecting that an appearance change in the
shape of the vibrating body 10 has occurred when the user folds (folds) the vibrating body 10.
Further, the voice output condition is also held as in the first embodiment.
[0089]
When the user changes the shape of the vibrating body 10 by breaking the vibrating body 10,
the shape change detection unit 42 detects the fact based on the electrical change generated
along with the act of breaking. Furthermore, when electrical change in the vibrating body 10 is
detected, the shape change detecting unit 42 detects the fact that the vibrating body 10 is
broken by comparing the detected electrical change with the shape change detection standard.
Do. The shape change detection unit 42 is also referred to as a broken position (hereinafter
referred to as a “folded position”) in the vibrator 10. ) Is also detected.
14-04-2019
26
[0090]
The fact that the vibrating body 10 is broken and the method of detecting the broken position
will be described in detail. Although four methods are illustrated below, other known methods
may be used. Also, a plurality of detection methods may be combined as appropriate.
[0091]
Method 1. Using Matrix Switch FIG. 10 is a circuit diagram including a matrix switch. P2-0 to P27 are the pin numbers of port 2 of the shape change detection unit 42 (control unit 40). The
vibrator 10 is provided with a plurality of switches. These switches are configured to turn on
when their installation point is broken. In the example of this figure, P2-0 to P2-3 are outputs,
and P2-4 to P-7 are inputs. Each input pin turns on its built-in pull-up resistor.
[0092]
With P2-0 set to Low and P2-1 to P2-3 set to High, the states of P2-4 to P2-7 are read. The
switch 148 located at the broken position is turned on, so that the corresponding pin goes low.
The switch installed at the non-folded position is turned off, and the corresponding pin becomes
high due to pull-up. The state of each switch can be acquired by sequentially switching the line to
be Low among P2-0 to P2-3 and reading out the state of P2-4 to P2-7 at the same time with this.
[0093]
The shape change detection unit 42 detects the fact that the vibrating body 10 is broken, on the
assumption that the shape change detection criterion is satisfied, when the presence of the
switch in the on state is detected. In addition, the shape change detection unit 42 may store in
advance the arrangement position of each switch 148 in the vibrator 10. The shape change
detection unit 42 may specify the arrangement position of each of the one or more switches
whose states are ON, and specify an area obtained by connecting the arrangement positions of
the switches as a broken position.
14-04-2019
27
[0094]
When the number of input ports of the shape change detection unit 42 (control unit 40) is
sufficient, each of the circuits including a plurality of switches is controlled by the shape change
detection unit 42 (control) as shown in the circuit configuration of FIG. You may connect to the
input port of part 40).
[0095]
Method 2.

configured such that the electrodes are shorted or disconnected when the vibrating body 10 is
broken. The shape change detection unit 42 detects the fact that the vibrating body 10 is broken
when it is detected that electrodes of a plurality of circuits disposed in the vibrating body 10 are
shorted or disconnected. Further, the shape change detection unit 42 may specify the broken
position by storing the arrangement position of each circuit in advance and specifying the
arrangement position of each circuit in which the electrode is shorted or disconnected.
[0096]
Method 3. Measurement of electrical resistance: Conductive carbon is applied to the surface of
the vibrating body 10. The reference holding unit 32 holds, as the shape change detection
reference, the value of the amount of electric resistance of the vibrating body 10 or the change
pattern of the amount of electric resistance (in other words, “transition pattern”) when the
vibrating body 10 is broken. . The shape change detection unit 42 constantly or periodically
measures the amount of electrical resistance of the vibrating body 10. The shape change
detection unit 42 detects the fact that the vibrator 10 is broken when the value of the amount of
electric resistance of the vibrator 10 or the change pattern of the amount of electric resistance
matches the shape change detection reference.
[0097]
Further, a plurality of conducting wires (electric wires) formed of a specific material (carbon
powder or the like) may be disposed in the vibrating body 10 so that the resistance value
14-04-2019
28
changes when it is bent. The reference holding unit 32 holds, as a shape change detection
reference, a change pattern of the amount of electric resistance of the lead accompanying the
bending of the lead. The shape change detection unit 42 constantly or periodically measures the
amount of electric resistance of each lead. The shape change detection unit 42 detects the fact
that the vibrating body 10 is broken when the change pattern of the electric resistance amount
of each lead wire matches the shape change detection reference.
[0098]
Each of the plurality of conductors may be connected to different input port pins of the shape
change detection unit 42 (control unit 40). The shape change detection unit 42 may store in
advance the arrangement position of each lead in the vibrator 10. The shape change detection
unit 42 identifies the lead wire whose electric resistance amount has changed among the
plurality of lead wires, and specifies the arrangement position of each lead wire whose electric
resistance amount has changed, thereby disposing the bent lead wire at the arrangement
position. The folding position may be identified based on the position.
[0099]
Method 4. Measurement of electromotive force: As in the first embodiment, the shape change
detection unit 42 detects the fact that the vibrating body 10 is broken based on the pattern of
power generated by the piezoelectric effect accompanying the breaking of the vibrating body 10
Do.
[0100]
Further, the shape change detection reference of the reference holding unit 32 may hold a
plurality of types of waveform patterns when various positions (areas) of the vibrating body 10
are broken, which are determined by prior experiments or the like. . Specifically, a plurality of
types of waveform patterns may be stored in association with identification information of a
plurality of bending positions. The shape change detection unit 42 specifies a waveform pattern
that matches the power generation information of the vibrating body 10 from a plurality of types
of waveform patterns as a shape change detection reference, and specifies a broken position
associated with the specified waveform pattern. You may Thereby, the shape change detection
unit 42 can identify the position / region folded in the vibrating body 10.
14-04-2019
29
[0101]
The shape change detection unit 42 may specify the shape of the vibrating body 10 as a result of
the bending based on the number of times of bending and the bending position detected by the
above method. For example, although not shown in FIG. 4, the storage unit 30 is a shape
information holding unit that holds dictionary data in which a combination of one or more
folding positions is associated with the shape of the vibrating body 10 as a result of folding. May
further be provided. The shape change detection unit 42 refers to the dictionary data to specify
the shape of the vibrating body 10 associated with the combination of one or more detected
folding positions, and identifies the shape as the current shape of the vibrating body 10 You may
In this case, the sound output condition of the reference holding unit 32 may be that the current
shape of the vibrating body 10 has become a predetermined shape.
[0102]
When the user determines in advance how to fold the vibrating body 10 (for example, the
bending position and the number of times of bending), the shape information holding unit of the
storage unit 30 has the number of times of bending and the shape of the vibrating body 10 as a
result of bending. Information may be associated and held. The shape change detection unit 42
may count the number of times of detection that the vibrator 10 is broken (that is, the number of
times of bending). Then, the shape associated with the specified number of folds may be
identified as the current shape of the vibrating body 10.
[0103]
The operation of the electroacoustic transducer 110 according to the second embodiment having
the above configuration will be described. A first operation example of the electroacoustic
transducer 110 is as shown in FIG. That is, the shape change detection unit 42 detects the fact
that the user has broken the vibrating body 10 (also referred to as the electroacoustic transducer
110). The audio output control unit 44 reproduces the audio data stored in the audio data
holding unit 34 when the audio output condition is satisfied. The item to be monitored in S10
may be at least one of the on / off state of a switch disposed inside the vibrator 10, the change in
the amount of electrical resistance, the state of electricity conduction, and the change in
electromotive force. . According to this aspect, it is possible to realize, for example, a concert
14-04-2019
30
ticket for playing music by being folded.
[0104]
The sound output condition may be that the vibrating body 10 has a specific shape (for example,
a shape of a crane). The shape change detection unit 42 may identify the current shape of the
vibrating body 10 that is the result of bending. The audio output control unit 44 may reproduce
the audio data on the assumption that the audio output condition is satisfied when the shape of
the vibrating body 10 is the above-described specific shape. According to this aspect, the shape
of the vibrating body 10 can be used as a password for listening to a secret message. For
example, it is possible to share a specific form in which voice output is permitted within the
family, and the family can hear the message but others can not hear the message.
[0105]
The audio data holding unit 34 may store plural types of audio data. The reference holding unit
32 outputs, as voice output conditions, voice data to be output for each of a plurality of fold
position candidates and “fold position candidate” which is information indicating a position /
region which may be broken in the vibrator 10. You may match and memorize | store the
information which shows the kind of. The shape change detection unit 42 may detect the broken
position of the vibrating body 10. The voice output control unit 44 may reproduce voice data
associated with the fold position candidate that matches the detected fold position. According to
this aspect, it is possible to realize, for example, an electro-acoustic transducer 110 in which
music played at a broken place is different. In addition, the amount of tear position candidates
can be suppressed by predetermining the broken position in the vibrating body 10, that is, the
position where the user should break the vibrating body 10.
[0106]
According to this aspect, various sounds can be output according to the broken position resulting
from the user's action. For example, when the broken position is the first position, the music of
the artist A may be reproduced. On the other hand, the music of artist B may be reproduced in
the case of the second position where the broken position is different from the first position.

The example which applies the electroacoustic transducer 110 of this aspect to a measure (a tape
measure and a ruler are included) is demonstrated. The scale portion of the measure is
configured to contain the vibrator 10. The voice data holding unit 34 holds identification
information of a plurality of bending positions in association with voice data indicating lengths.
This length may be the distance from the tip / start point of the measure to the break position.
When the shape change detection unit 42 detects the break position of the measure, the voice
output control unit 44 reproduces and outputs voice data associated with the break position. This
makes it possible to realize a measure that reads the length. In addition, you may match the
audio | voice data which show half of the distance from a front-end | tip-bending position to each
bending position. In this case, when the user bends the position where the measure is located,
half of the distance from the tip end to the broken position may be voice-outputted.
[0108]
Further, when the voice data holding unit 34 stores a plurality of types of voice data, the
reference holding unit 32 sets each of a plurality of types of shape candidates that the vibrator
10 can perform as a voice output condition and voice data to be output. Information indicating
the type may be associated and stored. The shape change detection unit 42 may identify the
current shape of the vibrating body 10, which is a result of bending, and determine which shape
candidate the shape matches. The audio output control unit 44 may reproduce audio data
associated with the current shape of the vibrating body 10.
[0109]
According to this aspect, as shown in FIG. 3, folding into a specific shape (in the shape of a crane
in FIG. 3) can realize folding origami. For example, folding into the shape of a dog generates a
dog's bark, and folding into the shape of a bat can realize origami that generates the sound of a
hitting ball (such as "kakine").
[0110]
A second operation example of the electroacoustic transducer 110 is as shown in FIG. That is,
14-04-2019
32
when the fact that the user breaks the vibrating body 10 (also referred to as the electroacoustic
transducer 110) is detected, the voice recording unit 46 obtains voice data from an external
device and stores the voice data in the voice data holding unit 34. The audio output control unit
44 reproduces and outputs the audio data stored in the audio data holding unit 34 when a
predetermined audio output condition is satisfied. Similar to the second operation example of the
first embodiment, according to this aspect, electroacoustics is provided by changing / updating
voice data provided from an external device (for example, voice data held by the external device)
as necessary. The content of the sound output from the converter 110 can be easily changed /
updated.
[0111]
Instead of acquiring voice data from an external device, the voice recording unit 46 may record
surrounding voice detected by the vibrator 10 to the voice data holding unit 34. Further, as the
sound output condition, it may be detected that the vibrating body 10 is broken. In this case, the
audio output control unit 44 may output the audio immediately when the audio data is provided
from the external device or the surrounding audio is recorded.
[0112]
FIG. 12 is a flowchart showing a third operation example of the electroacoustic transducer 110.
The shape change detection unit 42 monitors an electrical change of a predetermined monitoring
target item of the vibrator 10 (S50). When the electrical change of the monitoring target item is
detected (Y in S52) and the mode of the change matches the shape change detection criteria (Y in
S54), the shape change detection unit 42 determines the broken position in the vibrator 10 It
detects (S56).
[0113]
The bending position is a predetermined position for instructing start of recording (hereinafter
also referred to as "recording position"). If the voice recording unit 46 matches (Y in S58), the
voice recording unit 46 executes a recording process (S60). As a recording process, the voice
recording unit 46 may obtain voice data obtained by encoding surrounding voice via the vibrator
10 and store the voice data in the voice data holding unit 34. Further, as the recording process,
the voice recording unit 46 may obtain voice data from an external device and store the voice
14-04-2019
33
data in the voice data holding unit 34.
[0114]
Although the bending position is different from the recording position (N in S58), the
predetermined position for instructing the start of reproduction (hereinafter also referred to as
"reproduction position"). (Y at S62), the audio output control unit 44 executes the reproduction
process (S64). Specifically, the audio output control unit 44 reproduces and outputs the audio
data stored in the audio data holding unit 34. If the bending position is not the recording position
but the reproduction position (N in S62), the processing of FIG. In addition, if the electrical
change of the vibrator 10 is not detected (N in S52), or if the change mode does not match the
shape change detection reference (N in S54), the processing of FIG.
[0115]
Although the shape change detection unit 42 detects the broken position in FIG. 12, as described
above, the shape of the vibrating body 10 as a result of the bending may be identified. In this
case, the voice recording unit 46 may execute the recording process when it is detected that the
voice recording unit 46 has changed to a predetermined first shape for instructing the start of
recording. Further, the audio output control unit 44 may have a shape different from the first
shape, and may execute the reproduction process when it is detected that the second shape for
instructing to start reproduction has been changed.
[0116]
According to the third operation example of the electroacoustic transducer 110, it is possible to
realize a film speaker in which the aspect of the audio processing is different depending on the
broken position or the shape of the broken result. As a product to which such an electroacoustic
transducer 110 is applied, a roving invitation card, a roving birthday card, a roving photograph, a
roving postcard, etc. can be considered.
[0117]
14-04-2019
34
Here, consider a next-generation invitation in which four positions of a host recording position, a
host reproduction position, a guest recording position, and a guest reproduction position are
provided in advance. The host user folds the host recording position, sends a message to the
guest, and stores the message in the electroacoustic transducer 110. The guest user who
received the invitation folds the playback position for guest and listens to the host user's
message. Thereafter, the guest user folds the guest recording position, sends a message to the
host user, and causes the electroacoustic transducer 110 to store the message. The host user
receiving the returned invitation folds the playback position for host and listens to the guest
user's message.
[0118]
In addition to such invitations, it is possible to realize a reading invitation for a person with visual
impairment, that is, a reading invitation for reading out the contents of a message by bending the
playback position indicated by Braille or the like. That is, according to the electroacoustic
transducer 110, multimodal communication that promotes human-to-human communication can
be supported by a plurality of means including sight and hearing.
[0119]

[0121]
Here, it is assumed that the user folds the electroacoustic transducer 110 into a crane shape. The
information processing apparatus 202 detects a change in the shape of the electroacoustic
transducer 110 based on the imaging data acquired from the camera 204. The information
processing apparatus 202 notifies the electroacoustic transducer 110 of information related to
the detected shape change. The electroacoustic transducer 110 outputs a sound based on the
information notified from the information processing device 202.
[0122]
FIG. 14 is a block diagram showing a functional configuration of the electro-acoustic transducer
110 of FIG. The reference holding unit 32 in the third embodiment holds the voice output
condition, but does not hold the shape change detection reference. Further, the control unit 40
includes a shape change notification receiving unit 43 in place of the shape change detecting unit
42. The other configuration is the same as the electroacoustic transducer 110 of the first
embodiment.
[0123]
The shape change notification receiving unit 43 is also referred to as “information on shape
change notification” (hereinafter referred to as “shape change notification”) regarding the
shape change of the appearance of the electro-acoustic transducer 110 transmitted from the
information processing device 202. ) Is received via the communication unit 50.
[0124]

apparatus 202 of FIG. The information processing apparatus 202 includes a storage unit 70, a
control unit 80, and a communication unit 90. Although the figure shows a function for realizing
a film speaker in cooperation with the electro-acoustic transducer 110, it goes without saying
14-04-2019
36
that it may further comprise a known function as an information processing apparatus. For
example, it may further include an application execution unit that executes various applications
such as games.
[0125]
The communication unit 90 executes communication processing with an external device in
accordance with various communication protocols. In the third embodiment, in particular, near
field communication with the electroacoustic transducer 110 is performed.
[0126]
The storage unit 70 includes a reference holding unit 72 and an audio data holding unit 74. The
control unit 80 includes an imaging data acquisition unit 82, a shape change detection unit 84, a
shape change notification unit 86, and an audio data provision unit 88. Program modules
corresponding to these functional blocks may be stored in a predetermined recording medium
and installed in the storage of the information processing apparatus 202. In addition, the CPU of
the information processing apparatus 202 may store the program modules in the main memory
and appropriately execute the functions, as shown in FIG.
[0127]
The reference holding unit 72 corresponds to the reference holding unit 32 of the first
embodiment. The reference holding unit 72 holds a shape change detection reference, which is
reference data for detecting that an appearance change in shape has occurred in the
electroacoustic transducer 110 (in other words, the vibrator 10 of the electroacoustic transducer
110). The shape change detection reference in the third embodiment is image data to be
compared with the imaging data acquired from the camera 204.
[0128]
The shape change detection reference includes image data indicating the appearance of the
electroacoustic transducer 110 when the electroacoustic transducer 110 is broken, and the
14-04-2019
37
appearance of the electroacoustic transducer 110 when the electroacoustic transducer 110 is
broken. It includes the image data shown. Typically, the shape change detection reference
includes a plurality of image data corresponding to a plurality of broken positions, and a plurality
of image data corresponding to a plurality of broken positions. Hereinafter, image data as a
shape change detection reference is also referred to as reference image data.
[0129]
Note that the shape change detection reference may include information indicating the specific
shape of the electroacoustic transducer 110. For example, the shape change detection reference
may hold each of a plurality of reference image data in association with information indicating an
appearance aspect of the electro-acoustic transducer 110 indicated by each reference image
data. Here, the information indicating the appearance aspect is a broken state, a broken state, a
broken position 1, a broken position 2, a broken state, a rolled state, a shape of a crane, a shape
of a bat, a shape of an airplane, etc. It may be information indicating.
[0130]
The voice data holding unit 74 corresponds to the voice data holding unit 34 of the first
embodiment. The audio data holding unit 74 holds audio data to be reproduced and output by
the electroacoustic transducer 110.
[0131]
The imaging data acquisition unit 82 controls the operation of the camera 204. Further, the
imaging data acquisition unit 82 acquires imaging data obtained by imaging the electro-acoustic
transducer 110 by the camera 204.
[0132]
The shape change detection unit 84 corresponds to the shape change detection unit 42 of the
first embodiment. The shape change detection unit 84 compares the imaging data acquired by
the imaging data acquisition unit 82 with the plurality of reference image data stored as the
14-04-2019
38
shape change detection reference, so that the apparent shape of the electroacoustic transducer
110 is It detects that it has changed. In the comparison process, the shape change detection unit
84 may execute a known image matching process.
[0133]
For example, when the appearance of the electroacoustic transducer 110 indicated by the
imaging data matches the appearance of the electroacoustic transducer 110 indicated by any of
the reference image data, the shape change detection unit 84 determines the shape of the
electroacoustic transducer 110. It may be determined that a change has occurred. The shape
change detection unit 84 may also determine that the shape change has occurred in the electroacoustic transducer 110 when the imaging data matches reference image data different from the
reference image data matched at the previous determination.
[0134]
When the shape change detection reference includes specific shape information of the electroacoustic transducer 110, the shape change detection unit 84 determines the specific shape of the
electro-acoustic transducer 110 associated with the reference image data matching the imaging
data. May be further specified. In the example of FIG. 13, the shape change detection unit 84 may
specify that the electroacoustic transducer 110 is currently in the shape of a crane.
[0135]
When the shape change detection unit 84 detects a shape change of the electro-acoustic
transducer 110, the shape change notification unit 86 transmits a shape change notification to
the electro-acoustic transducer 110 via the communication unit 90. The shape change
notification may be, for example, information indicating the fact that a shape change has
occurred in the electro-acoustic transducer 110, or information indicating a specific shape of the
electro-acoustic transducer 110. Moreover, the information which shows a tearing position or a
bending position may be sufficient.
[0136]
The audio data provision unit 88 transmits the audio data stored in the audio data holding unit
14-04-2019
39
74 to the electroacoustic transducer 110 via the communication unit 90.
[0137]
Although not shown in FIG. 14, the control unit 80 further accesses the predetermined external
server via the communication unit 90, further acquires the audio data from the external server
and further stores the audio data acquisition unit in the audio data storage unit 74. May be
included.
The audio data acquisition unit may acquire, from an external server, audio data corresponding
to the shape change of the electro-acoustic transducer 110 when the shape change is detected.
For example, when the electro-acoustic transducer 110 changes to a dog shape, voice data
indicating a dog's bark may be acquired. Also, the voice data acquisition unit may periodically
access the external server to obtain voice data that is periodically changed and updated.
[0138]
The operation of the information processing apparatus 202 and the electroacoustic transducer
110 having the above configuration will be described. FIG. 16 is a flowchart showing a first
operation example of the information processing apparatus 202. When the imaging application is
activated in the information processing apparatus 202 (Y in S70), the imaging data acquisition
unit 82 starts imaging processing of the camera 204 and acquires imaging data output from the
camera 204 (S72). The imaging application may be an application that controls audio processing
of the electroacoustic transducer 110. Moreover, the game application which displays the game
which used the electroacoustic transducer 110 may be sufficient.
[0139]
When the imaging data acquired from the camera 204 matches the shape change detection
standard (Y in S74), the shape change detection unit 84 detects the fact that the shape change
occurs in the electroacoustic transducer 110 (S76). As mentioned above, the shape change
detection unit 84 may identify the current shape of the electroacoustic transducer 110. The
shape change notification unit 86 transmits a shape change notification regarding the current
shape to the electroacoustic transducer 110 (S78). If the imaging data is inconsistent with the
14-04-2019
40
shape change reference (N in S74), S76 and S78 are skipped.
[0140]
When the execution of the imaging application is continued in the information processing
apparatus 202 (N in S80), the process returns to S72 and acquires imaging data again. When the
execution of the imaging application is ended (Y in S80), the process of FIG. If the imaging
application has not been activated (N in S70), the processing after S72 is skipped, and the
processing of FIG.
[0141]
FIG. 16 is a flowchart showing a first operation example of the electro-acoustic transducer 110
corresponding to the first operation example of the information processing apparatus 202. When
the shape change notification receiving unit 43 receives the shape change notification (Y in S90),
the voice recording unit 46 acquires voice data based on surrounding sound through the
vibrating body 10, and the voice data is stored in the voice data holding unit Store to 34 (S92). If
the shape change notification has not been received (N at S90), S92 is skipped. When the voice
output condition is satisfied (Y in S94), the voice output control unit 44 causes the vibrator 10 to
output voice based on the voice data stored in the voice data holding unit 34 (S96). If the voice
output condition is not satisfied (N in S94), S96 is skipped.
[0142]
Although FIG. 17 shows an example in which the surrounding voice is recorded triggered by the
reception of the shape change notification, voice data may be acquired from the information
processing apparatus 202 as in the first and second embodiments. . If the audio data to be
reproduced has been stored in the audio data holding unit 34 in advance, the recording process
of S92 may be skipped. The voice output condition may be that the shape change notification has
been received. That is, the electro-acoustic transducer 110 may immediately reproduce and
output the audio data stored in advance in the audio data holding unit 34 in response to the
reception of the shape change notification.
[0143]
14-04-2019
41
FIG. 18 is a flowchart showing a second operation example of the information processing
apparatus 202. Instead of the process of S78 of the first operation example, the process of S79 is
executed in the second operation example. That is, when the shape change of the electroacoustic
transducer 110 is detected, the shape change notification unit 86 transmits a shape change
notification to the electroacoustic transducer 110, and at the same time, the audio data providing
unit 88 generates predetermined audio data. It transmits to the electroacoustic transducer 110
(S79). The other processes are the same as in the first operation example (FIG. 16).
[0144]
FIG. 19 is a flowchart showing a second operation example of the electro-acoustic transducer
110 corresponding to the second operation example of the information processing apparatus
202. When the shape change notification receiving unit 43 receives the shape change
notification (Y in S90), the voice recording unit 46 is in a reception standby state for voice data.
When the voice recording unit 46 receives the voice data transmitted from the information
processing apparatus 202 (Y in S91), the voice recording unit 46 stores the received voice data
in the voice data holding unit 34 (S93). If the shape change notification has not been received (N
in S90) or the voice data has not been received (N in S91), S93 is skipped. The processes of S94
and S95 are the same as in the first operation example (FIG. 16). In the aspect of the operation
example 2, by changing / updating the audio data provided from the information processing
apparatus 202 as necessary, it is possible to easily change / update the content of the audio
output by the electro-acoustic transducer 110.
[0145]
In the third embodiment, the information processing apparatus 202 detects a change in the
shape of the electroacoustic transducer 110 based on imaging data by the camera 204. Since the
shape change is detected based on the image, and the data processing capability of the
information processing apparatus 202 is usually higher than the data processing capability of
the electroacoustic transducer 110, the accuracy of shape change detection can be enhanced.
[0146]
14-04-2019
42
Further, as described above, the difference between the third embodiment and the first
embodiment and the second embodiment is the main body that detects the change in shape of
the electroacoustic transducer 110. Therefore, the processing (for example, voice recording
processing and voice output processing) of the electro-acoustic transducer 110 after shape
change detection can be executed in various aspects described in the first embodiment and the
second embodiment.
[0147]
For example, the information processing apparatus 202 may transmit, to the electroacoustic
transducer 110, information indicating the current shape after change (for example, the shape of
a crane) or information indicating a broken position or a broken position as the shape change
notification. . The electro-acoustic transducer 110 performs the voice recording process
described in the first and second embodiments based on the current shape, the broken position,
and the broken position of the electro-acoustic transducer 110 notified from the information
processing device 202. And voice output processing may be performed.
[0148]
Although not shown in FIGS. 15 and 17, the application execution unit of the information
processing apparatus 202 applies the fact of the detection of the shape change of the
electroacoustic transducer 110 when the shape change detection unit 84 detects the shape
change. It may be reflected in the execution result of As a result, the voice output from the
electro-acoustic transducer 110 itself whose shape has been changed by the user can be linked
to the execution result of the application, and a novel entertainment experience can be provided
to the user.
[0149]
For example, the application execution unit may change the reproduction result of the game
application according to the shape, the broken position, the broken position, and the like of the
electroacoustic transducer 110 after the change. As a specific example, during the battle with the
enemy character in the game, if the user folds the electro-acoustic transducer 110 into a dog
shape, the application execution unit may display a dog as an ally character on the screen. The
shape change notification unit 86 may transmit a shape change notification to the electroacoustic
14-04-2019
43
transducer 110 in synchronization with the screen display of the dog. The dog-shaped electroacoustic transducer 110 may output the dog's bark in accordance with the voice data stored in
advance or the voice data provided from the information processing device 202 in response to
the reception of the shape change notification.
[0150]
The present invention has been described above based on three embodiments. It is understood
by those skilled in the art that these embodiments are exemplifications, and that various
modifications can be made to the combination of each component and each processing process,
and such modifications are also within the scope of the present invention. It is a place.
[0151]
In the third embodiment, the electroacoustic transducer 110 holds the audio output condition,
but as a modification, the information processing apparatus 202 holds the audio output
condition and determines whether the audio output condition is satisfied or not. It is also good.
When applied to the first operation example, the information processing device 202 may notify
the electro-acoustic transducer 110 of that when the audio output condition is satisfied. The
electro-acoustic transducer 110 may reproduce and output the audio data on condition that the
audio output condition satisfaction has been notified. Applying to the second operation example,
the information processing device 202 may transmit voice data to the electroacoustic transducer
110 when the voice output condition is satisfied. When the electroacoustic transducer 110
receives audio data from the information processing device 202, the electroacoustic transducer
110 may immediately reproduce and output the audio data.
[0152]
