[0030]
Here, the middle portions 101 c and 102 c may include or may not include the midpoint in the
length direction of the plate springs 101 and 102.
That is, the ends 101a and 101b are not limited to the same length.
[0031]
Further, in the plate springs 101 and 102 in this example, the end portions 101a ′ and 102a ′
of the end portions 101a and 102a are bent and fixed to the bottom portion of the housing
portion 6 like the middle portions 101c and 102c. (See Figure 3). In this way, since the ends
101a and 102a inside the housing 6 are fixed to the bottom of the housing 6 at both ends, the
leaf springs 101 and 102 can support the yoke 5 substantially horizontally. As a result, the yoke
5 can be vibrated parallel to the height direction inside the housing portion 6.
[0032]
Furthermore, in this example, the plate spring 101 on the side of the left arm 5 b is bonded to
the yoke 5 via the insulating seal 7. The insulating seal 7 is made of, for example, an insulating

[0037]
Ends 3a and 3b which are lead wires of the coil 3 are connected to the plate springs 101 and
102, respectively. One end 3 a drawn from the coil 3 is extended along the lower surface of the
diaphragm 2 and the inner wall of the housing 6 and connected to the end 101 a of the plate
spring 101. Here, since the left side surface of the yoke 5 on the side where the end 3a is
extended is covered with the insulating seal 7, the end 3a and the yoke 5 are not electrically
shorted.
[0038]
The other end 3 b drawn from the coil 3 extends along the lower surface of the diaphragm 2 and
reaches the upper surface of the yoke 5 at a position where the insulation distance with the coil
3 can be maintained, and is connected to the yoke 5. Here, since the yoke 5 and the plate spring
102 are electrically connected, the end 3 b and the plate spring 102 are electrically connected.
Thus, the plate springs 101 and 102 constitute a spring terminal for the coil, and an audio signal
to be supplied to the coil 3 and a vibration generation signal can be input between the terminals
of the plate springs 101 and 102.
[0039]
Weights 9a and 9b are joined to the lower surfaces of the left and right arms 5b and 5c of the
yoke 5, respectively. An adhesive is used to bond the weight 9a to the lower surface of the left
arm 5b. An adhesive is also used to bond the weight 9b to the lower surface of the right arm 5c.
The weight of each of the weights 9a and 9b is, for example, about 0.597 [g]. The thickness of
each of these weights 9a and 9b is about 2 mm, and is approximately equal to the distance from
the lower surface of each of the left and right arms 5b and 5c to the bottom surface of the
housing portion 6. A very slight gap is provided between the lower surface of the weights 9 a and
9 b and the bottom surface of the housing portion 6. This is to secure a stroke (space) between
the upper and lower portions of the yoke 5 in the direction of the coil winding shaft while
securing the weight of the weights 9a and 9b. In this example, weights 9 a and 9 b are connected
to the inside of the plate springs 101 and 102 of the yoke 5.

In the leaf spring 101 on the side of the left arm 5b shown in the Y1-Y1 arrow sectional view of
FIG. 2 in FIG. 3, when the middle portion 101c and the end portion 101a ′ are embedded in the
bottom of the housing portion 6, the housing It is fixed to the part 6. In this example, the end
portion 101a ', together with the middle portion 101c, constitutes a movable fulcrum of the end
portion 101a. The leaf spring 101 and the housing portion 6 have an embedded integral
structure.
[0041]
The end portion 101a extended inside the housing portion 6 has an arc-curved shape, and a flat
portion 101e to be a connecting portion of the yoke 5 is provided at the curved upper portion.
The flat portion 101 e is substantially parallel to the bottom surface of the housing portion 6.
Further, bent portions 101d for increasing the elastic force and the vibration width in the vertical
direction of the end portion 101a are provided at both ends of the flat portion 101e. The vertical
direction referred to here is the height direction of the housing portion 6.
[0042]
On the other hand, the end portion 101b of the housing portion 6 which is extended to the
outside has a curved end 101b 'so that the curved outer surface is in contact with the external
electrode. The end portion 101 b has an elastic force by extending obliquely with respect to the
bottom surface of the housing portion 6, and the end portion 101 b ′ constitutes a suitable
contact portion to the external electrode.
[0043]
Thus, the leaf spring 101 has the functions of the support member and the lead-out electrode.
Further, the plate spring 102 on the side of the right arm 5c is configured in the same manner,
and has the functions of a support member and a lead-out electrode. Further, in this example, the
end 3a of the coil 3 connected to the side of the plate spring 101 is sandwiched between the flat
portion 101e and the insulating seal 7 and connected to the plate spring 101. In this way, the
end 3 a of the coil 3 is more firmly maintained in the connected state between the plate spring
101 and the yoke 5.

[0044]
FIG. 4 is an exploded perspective view showing an assembly example of the speaker 100 with an
actuator function. According to the speaker 100 with the actuator function shown in FIG. 4, first,
the housing portion 6 is prepared. In this example, the housing 6 is provided with openings 6a
and 6b at the bottom, and housings 6e and 6f for restricting the movement of the flat springs
101 and 102 for the purpose of attachment. A predetermined mold is prepared, and an ABS resin
or the like is injected into the mold to form a resin molded product. PC resin may be used instead
of ABS resin.
[0045]
At this time, even if the plate springs 101 and 102 are attached to the housing reinforcing
portions 6e and 6f inside the housing portion 6 by a press-fitting method, the plate springs 101
and 102 are incorporated into a mold and the housing portion 6 simultaneously. It may be insert
molding.
[0046]
A conductive band member curved so as to have elasticity is used for the leaf springs 101 and
102.
For the plate springs 101 and 102, for example, one obtained by pressing a phosphor bronze
plate having a thickness of about 0.5 mm is used. The plate springs 101 and 102 are plated. For
example, Ni plating of about 2 to 3 μm, Ni-pd plating of about 1 to 3 μm, and Cu plating of
about 0.03 μm are applied to members constituting the plate springs 101 and 102. Thereby, the
housing part 6 as a container which can accommodate the parts for vibration etc. is obtained.
[0047]
Next, the magnet 4 and weights 9a and 9b are attached to the yoke 5. As the yoke 5, one having
a bottomed cylindrical recess 5a at the central portion and arms 5b and 5c on the left and right
is used. When the length of the yoke 5 is L ', the width is W', and the height is H ', the width L' is
about 10 mm, the width W 'is about 3 mm, The height H 'is about 1.5 mm. In this example, a
12-04-2019
13
stainless steel plate (SUS301) having a thickness of about 0.3 mm is press-pressed to form a
bottomed cylindrical recess 5a at the center and a yoke 5 having arms 5b and 5c on the left and
right.
[0048]
Here, the insulating seal 7 is attached or adhered to the left arm 5b. For the insulating seal 7, for
example, a PET (polyethylene terephthalate) film (seal) having a thickness of about 25 μm and
having adhesiveness on one side is used. Here, the insulating seal 7 is attached so as to cover the
upper surface, the side surface, and the lower surface of the left arm 5b.
[0049]
The magnet 4 is joined to the bottom of the bottomed cylindrical recess 5 a of the yoke 5. For
example, bonding is performed using a urethane-based adhesive. For the magnet 4, a magnetic
member having a prismatic shape such as neodymium is used.
[0050]
An adhesive is used to bond the weight 9a to the lower surface of the left arm 5b. An adhesive is
also used to bond the weight 9b to the lower surface of the right arm 5c. The weight of each of
the weights 9a and 9b is, for example, about 0.597 [g]. Use an urethane-based adhesive. Thereby,
a component for vibration that can be accommodated inside the housing portion 6 is obtained.
[0051]
Next, the diaphragm 2 and the coil 3 are joined to form a voice coil component. As the
diaphragm 2, a film member having a thickness of about 25 μm and substantially the same size
as the lid member 1 is used. PEN or PET is used for the film member, and the diaphragm 2 is
processed into a cone shape. For the coil 3, a copper wire of about 0.05 mm is used. The coil 3 is
formed in a hollow shape in which a copper wire is wound in a prismatic shape a predetermined
number of times.
12-04-2019
14
[0052]
When the diaphragm 2 and the coil 3 are prepared, one side of the prismatic coil 3 is joined to
the center of the back surface of the diaphragm 2. At this time, the diaphragm 2 and the coil 3
are bonded using a urethane-based adhesive. As a result, a voice coil component attachable to the
upper portion of the housing portion 6 is obtained.
[0053]
When the parts for vibration and the voice coil part described above are prepared, they are
housed, for example, in the housing part 6 with the leaf springs 101 and 102, and the speaker
100 with the actuator function is assembled.
[0054]
In this example, at the time of storage, the end 3 a of the coil 3 is soldered to the end 101 a of
the plate spring 101 inside the housing 6.
The end 3a is preferably connected to the upper surface of the flat portion 101e of the plate
spring 101, but may be bonded to another portion of the plate spring 101 in consideration of
assembly efficiency.
[0055]
Alternatively, a conductive thin film electrically connected to the middle portion 101 c of the leaf
spring 101 may be formed on the inner wall of the housing 6 by printing or the like, and the end
3 a may be soldered to the thin film. .
[0056]
Similarly, inside the housing portion 6, the lead wire 3 b of the coil 3 is soldered and connected
to the upper surface of the right arm 5 c of the yoke 5.
[0057]
12-04-2019
15
Thereafter, the yoke 5 is attached to the housing portion 6.
At this time, the lower surfaces of the left and right arms 5b and 5c of the yoke 5 are bonded to
the upper surfaces of the flat portions 101e and 102e of the plate springs 101 and 102,
respectively.
The plate spring 101 may be adhered to the left arm 5b to which the insulating seal 7 is attached
by an insulating adhesive, an adhesive member, or the like. The plate spring 102 may be bonded
(welded) to the right arm 5c by a conductive adhesive, a bonding member, or soldering.
[0058]
Thereafter, the diaphragm 2 to which the coil 3 is joined is fitted from the top of the housing
portion 6. At this time, the winding shaft portion of the coil 3 is incorporated so as to cover the
magnet 4. Thereafter, the lid member 1 and the housing portion 6 are aligned, and the outer
edge portion is joined using an adhesive or the like so that the outer edge portion of the
diaphragm 2 is sandwiched between the lid member 1 and the housing portion 6. Thereby, as
shown in FIG. 1, the speaker 100 with an actuator function in which the yoke 5 is movable inside
the housing portion 6 is completed.
[0059]
As described above, according to the speaker 100 with the actuator function as the first
embodiment of the present invention, the bottom portion of the housing portion 6 is provided
with the pair of leaf springs 101 and 102 fixed with the intermediate portion as the movable
fulcrum One end of the leaf spring 101, 102 is extended into the housing 6 to support the yoke
5, and the other end is extended outside the housing 6 to form a lead-out electrode for signal
input It is.
[0060]
With this configuration, the movable fulcrum, the support member, and the lead-out electrode
can be configured by one member, so the number of parts applied to the speaker 100 can be
reduced.

9b is not inhibited, both end portions in the longitudinal direction of the yoke 205 can be
vibrated with a large swing width efficiently.
[0085]
In addition, since the plate springs 201 and 202 are not disposed at both ends of the housing
portion 206, the length of the speaker 200 in the longitudinal direction can be reduced. This
makes it possible to provide an ultra-compact receiver (receiver) with an actuator function, and

the opposite direction to the end 301 a, and the curved outer surface forms a spring terminal for
the lead-out electrode.
Thus, the leaf spring 301 has the function of the support member of the yoke 5 and the lead-out
electrode of the end 3a.
[0093]
The plate spring 302 on the side of the right arm 5c is configured substantially the same as 301,
and is connected to the right arm 5c in a conductive manner. As in the first embodiment, by
connecting the end 3 b of the coil 3 to the yoke 5, the plate spring 302 has the function of
supporting the yoke 5 and the lead-out electrode of the terminal 3 b.

24
housing portion 6.
[0096]
As a result, the leaf springs 301 and 302 can be miniaturized, and a receiver (receiver) with an
ultra-compact actuator function can be provided. Therefore, as in the first embodiment, the
receiver can be sufficiently applied to an input device with a haptic function on the display unit
side of the portable telephone (terminal device).

Further, instead of the insulating nut 7a, a predetermined portion of the left arm 5b of the yoke 5
may be made of an insulating member. Alternatively, the left arm 5b in which the screw hole 7b
is opened may be coated with an insulating member. Thus, the spring terminal 401 has the
function of the supporting member of the yoke 5 and the spring terminal for the lead-out
electrode of the end 3a.
[0118]

spring terminal 402 has a function as a support member of the yoke 5 and a spring terminal for
the lead-out electrode of the end 3 b.
[0119]
When assembling the speaker 400 of this example, the spring terminals 401 and 402 in a state
where the screw parts 411 and 412 on the upper terminal side are removed are insert-molded at
the time of injection formation of the housing part 6 and the screw parts 411 and 412 are
screwed. It is preferable that the yoke 5 be connected to the member on the side of the housing
portion 6 by fitting.
[0120]
At that time, the spring 401 d and the screw portion 411 can be in electrical contact by being
pressed to each other.
Alternatively, since the screw portion 411 and the nut tube portion 421 are connected /
conductively engaged with each other, the upper end portion of the spring 401 d may be
connected to the upper side of the nut tube portion 421. .
[0121]
Alternatively, the terminal of the spring 401 d may be drawn out from the screw hole of the nut
tube 421 and connected to the screw 411 by soldering or the like, and then the screw 411 may
be screwed into the nut tube 421.

As described above, according to the speaker 400 with the actuator function as the fourth
embodiment, the spring terminals 401 and 402 which can extend and contract in the height
direction of the housing portion 6 and which can vibrate are set in the longitudinal direction of
the yoke 5. While both ends are movably supported, the lead-out electrode of the coil 3 is
configured.
[0123]
Accordingly, since the left and right arms 5b and 5c of the yoke 5 vibrate with a predetermined
swing width according to the elastic force of the springs 401d and 402d, the swing width can be
easily adjusted by appropriately changing the spring used. it can.
This makes it easy to control the magnitude of the swing width of the yoke 5.
Further, since the spring terminals 401 and 402 expand and contract in parallel with the height
direction of the housing portion 6, the vibration direction of the yoke 5 is stabilized.
[0124]
Further, the support member for the yoke and the lead-out electrode for the coil can be
constituted by one member engaged in a rod shape. This makes it possible to provide an ultracompact receiver (receiver) with an actuator function, and in the same manner as in the first
embodiment, the receiver is used as an input with a haptic function on the display unit side of a
portable telephone (terminal device). It becomes applicable enough to the device.
[0125]

2) of the speaker 36b in the upper housing 20. FIG.
[0146]
The board | substrate 65 for electronic component mounting is provided in the board | substrate
side case 20a shown to FIG. 12A.
On the substrate 65, flat plate electrodes (land electrodes) 66a and 66b for speakers are
provided, and an audio signal and a vibration generation signal are applied.
[0147]
In this example, in the panel side case 20b shown in FIG. 12B, the input means 24 and the
display means 29 have upper and lower straight ribs 64a, 64b, with the back light side (not
shown) of the display means 29 facing upward. It is supported by the straight ribs 64c on the left
side and 64b on the left side, and has a mounting structure capable of moving in the right
direction. In this example, the input unit 24 and the display unit 29 are mounted such that the
right side thereof is in contact with the side surface of the speaker 36b.

107a and 107b facing upward in the panel case 20b. The mounting structure can be moved
leftward. Here, the lead-out electrodes 107a and 107b correspond to the spring terminals 101
and 102 of the first embodiment, and have a support member for the yoke of the speaker 36b
and a lead-out electrode for the coil. In this example, the speaker 36 b is mounted such that the
left side thereof abuts (presses) the input means 24 and the side surface (wood surface) of the
display means 29.

[0149]
Thereafter, as shown in FIG. 13, the substrate case 20a and the panel case 20b are aligned and
engaged. At this time, the flat plate electrode 66a and the extraction electrode 107a are brought
into contact with each other and brought into electrical signal conduction. Similarly, the flat plate
electrode 66b and the lead-out electrode 107b are brought into contact with each other and
brought into electrical signal conduction. Thereby, when the input detection means 45 detects
the contact position of the operator who performs the input operation on the display screen, the
yoke 5 vibrates in the housing portion 6 based on the vibration generation signal, whereby the
input means 24 and the display means 29 Can be transmitted to the At this time, the speaker 36
b with the actuator function vibrates the display screen from the side direction based on the
position information obtained from the input detection unit 45.
[0150]
Next, a mobile phone 500 with a tactile input function will be described. FIG. 14 is a block
diagram showing a configuration example of a control system of the mobile telephone 500 and a
touch feedback function example thereof.
[0151]
A mobile telephone 500 shown in FIG. 14 is configured by mounting blocks of each function on
the circuit board 17 of the lower housing 10. The parts corresponding to the parts and means
shown in FIGS. 10 to 13 are denoted by the same reference numerals. The portable telephone
500 includes a control unit 15, an operation panel 18, a receiving unit 21, a transmitting unit 22,
an antenna duplexer 23, an input detection unit 45, a display unit 29, a power supply unit 33, a
camera 34, a microphone 13, a storage unit 35, an incoming call. It has a speaker 36a for melody
and a speaker 36b with an actuator function.
[0152]
Although the input detection means 45 shown in FIG. 14 has been described with reference to
FIG. 13 as an electrostatic capacitance type input device, it may be anything as long as it can
distinguish the function of cursoring and selection. It may be an input device such as (SAW),
12-04-2019
38
optical system, multi-stage tact switch, or the like, and preferably it may be an input device
having a configuration in which position detection information and force detection information
are given to the control means 15. The input detection means 45 described above receives at
least the position detection signal S1 and the input detection signal S2 as an input amount
(pressing force; pressing force F) via the finger 30a of the operator 30.
[0153]
The control unit 15 constitutes a control system, and includes an image processing unit 26, an A
/ D driver 31, a video & audio processing unit 44, a CPU 32 and a memory unit 37. The position
detection signal S1 and the input detection signal S2 from the input detection unit 45 are
supplied to the A / D driver 31. The A / D driver 31 converts an analog signal composed of the
position detection signal S1 and the input detection signal S2 into digital data in order to
distinguish the functions of cursoring and icon selection. In addition to this, the A / D driver 31
performs arithmetic processing on this digital data to detect whether it is a cursoring input or
icon selection information, and distinguishes whether it is a cursoring input or an icon selection
flag data D3 or position detection information D1 or input detection The information D2 is
supplied to the CPU 32. These calculations may be performed within the CPU 32.
[0154]
The CPU 32 is connected to the A / D driver 31. The CPU 32 controls the entire telephone based
on a system program. The storage means 35 stores system program data for controlling the
entire telephone set. A RAM (not shown) is used as a work memory. When the power is turned
on, the CPU 32 reads system program data from the storage means 35 and develops it in a RAM,
starts up the system, and controls the entire mobile phone. For example, the CPU 32 receives the
position detection information D1 from the A / D driver 31, the input detection information D2,
and the flag data D3 (hereinafter, also simply referred to as input data) and supplies
predetermined command data D to the power supply unit 33, the camera 34, Control is
performed to supply devices such as the storage unit 35, the memory unit 37, the video & audio
processing unit 44, etc., to capture reception data from the reception unit 21, and to transfer
transmission data to the transmission unit 22.
[0155]
12-04-2019
39
In this example, the CPU 32 compares the input detection information D2 obtained from the
input detection unit 45 with the preset pressing determination threshold Fth, and performs
vibration control of the speaker 36b with the actuator function based on the comparison result.
The memory unit 37 is read and controlled. For example, assuming that the tactile sensations
propagated from the input detection surface at the depressed position of the input detection
means 45 are A and B, the tactile sensation A lowers the input detection surface according to the
pressing force F of the operator's finger 30a at the depressed position. It is obtained by changing
from the vibration pattern of frequency and small amplitude to the vibration pattern of high
frequency and large amplitude. In addition, the sense of touch B is obtained by changing the
input detection surface according to the pressing force F of the operator's finger 30a at the
pressed position from the high frequency and large amplitude vibration pattern to a low
frequency and small amplitude vibration pattern. Be
[0156]
The storage means 35 is connected to the above-mentioned CPU 32, and for example, display
information D4 for displaying a display screen for input item selection three-dimensionally and a
selection position of an icon corresponding to the display information D4 and a vibration mode
Control information Dc and the like related to each is stored for each display screen. The control
information Dc can generate a plurality of different senses of touch synchronized with an
application (three-dimensional display or various display contents) in the display means 29, and
generate a plurality of specific vibration waveforms to generate the sense of touch, An algorithm
is included to set a specific haptic generation mode for each application. An EEPROM, a ROM, a
RAM or the like is used as the storage means 35.
[0157]
In this example, the CPU 32 performs the display control of the display means 29 and the output
control of the speaker 36b with the actuator function based on the position detection
information D1, the input detection information D2 and the flag data D3 output from the A / D
driver 31. . For example, the control unit 15 reads the control information Dc from the storage
unit 35 based on the position detection signal S1 obtained from the input unit 24 and the input
detection signal S2 obtained from the force detection units 55a to 55d, and accesses the memory
unit 37. Then, control is performed to supply the vibration generation signal Sout2 to the
speaker 36b with the actuator function.
12-04-2019
40
[0158]
For example, when the input detection unit 45 detects the input detection information D2
exceeding the pressing determination threshold Fth, the CPU 32 activates the sense of touch A
and then detects the input detection information D2 below the pressing determination threshold
Fth. The memory unit 37 is read out and controlled so as to start up. In this way, different
vibration patterns can be generated according to the "pressure" of the operator's finger 30a or
the like.
[0159]
A memory unit 37 is connected to the CPU 32, and the vibration generation data Da is read
based on control information Dc from the CPU 32. The vibration generation data Da has an
output waveform consisting of a sine waveform. A video and audio processing unit 44 is
connected to the memory unit 37, each vibration generation data Da is supplied to the video and
audio processing unit 44, and the vibration generation data Da is subjected to audio processing
(digital / analog conversion, amplification, etc.) The vibration generation signal Sout2 is supplied
to the speaker 36b with the actuator function. The speaker 36b is made to vibrate based on the
vibration generation signal Sout2.
[0160]
In this example, the memory unit 37 stores the pressing determination threshold Fth
corresponding to each application. For example, the pressing determination threshold Fth is
stored in advance in a ROM or the like provided in the storage unit 35 as a trigger parameter.
The storage unit 35 receives the control of the CPU 32, receives the input detection information
D2, compares the preset pressing determination threshold Fth with the pressure F obtained from
the input detection information D2, and determines that Fth> F. Processing or determination
processing such as Fth ≦ F is executed.
[0161]
For example, when the pressing determination threshold Fth = 100 [gf] is set in the memory unit
37, the input detection surface is vibrated based on the vibration pattern for obtaining the touch
12-04-2019
41
of the classic switch. Further, when the pressing determination threshold Fth = 20 [gf] is set, the
input detection surface is vibrated based on the vibration pattern for obtaining the touch of the
cyber switch.
[0162]
An image processing unit 26 is connected to the CPU 32 in addition to the memory unit 37, and
image processing is performed on display information D4 for three-dimensionally displaying
button icons and the like. The display information D4 after image processing is supplied to the
display means 29. In this example, the CPU 32 controls display of the display means 29 so as to
three-dimensionally display button icons in the display screen in a depth direction with
perspective.
[0163]
The input device 90 configured in this way, for example, presses (contacts) one of a plurality of
button icons displayed on the display screen for input item selection to set the input means 24 in
the Z direction on the display screen. When pressed, the screen input operation is performed
with a sense of touch. The operator 30 receives vibration from the finger 30a and feels vibration
for each button icon as a tactile sensation.
[0164]
The display content of the display means 29 is such that the emitted sound from the speakers
36a, 36b, etc. is judged by the operator's eyes 30b, and the respective functions are judged by
the auditory sense of the operator's ear 30c. The operation panel 18 is connected to the CPU 32
described above, and is used, for example, when manually inputting the telephone number of the
other party. In addition to the above-described icon selection screen, the display unit 29 may
display an incoming call video based on the video signal Sv.
[0165]
The antenna 16 shown in FIG. 14 is connected to the antenna duplexer 23, and receives a radio
12-04-2019
42
wave from the other party from a base station or the like when an incoming call is received. A
receiving unit 21 is connected to the antenna duplexer 23, receives received data guided from
the antenna 16, demodulates video and audio, and outputs the demodulated video and audio data

44 through the CPU 32. The digital audio data is converted from digital to analog to output an
audio signal Sout1. The digital video data is converted from digital to analog and converted to a
video signal. It is made to output Sv.
[0166]
Connected to the video & audio processing unit 44 are a speaker 36a for configuring a large
sound and a speaker 36b with an actuator function for configuring a receiver. The speaker 36a is
configured to ring a ringing tone, a ringing tone, or the like based on the acoustic signal Sout1
when an incoming call is received. The speaker 36b receives the audio signal Sout2 to expand
the other party's speech 30d and the like. The speaker 36b vibrates based on the vibration
generation signal Sout2 at the time of tactile presentation.
[0167]
In addition to the speakers 36a and 36b, a microphone 13 constituting a transmitter is
connected to the video & audio processing unit 44, and the voice of the operator is collected to
output an audio signal Sin. The video & audio processing unit 44 analog / digital converts an
analog audio signal Sin to be sent to the other party at the time of calling, outputs digital audio
data, or analog / digital converts an analog video signal Sv. Digital image data is output.
[0168]
