[0014]
Hereinafter, a portable music apparatus according to a preferred embodiment of the present
invention will be described with reference to the drawings.
[0015]
First Embodiment A portable music apparatus 100 according to a first embodiment of the
present invention includes data (for example, MP3 (MPEG1 Audio Layer-3), etc.) stored in the
storage unit 103 as shown in the block diagram of FIG. It is an apparatus capable of reproducing
music data).
The portable music apparatus 100 includes a control unit 101, an operation unit 102, a storage
08-05-2019
4
unit 103, a display unit 104, a terminal 118, and an earphone 119.
The user can listen to the reproduced music via the earphone 119.
[0016]
The operation unit 102 includes an optical slide 112, a button switch 113, and the like, and
inputs instruction information according to the user's operation.
For example, if the user follows the surface of the optical slide 112 in the positive direction with
the finger, the reproduction volume of the music data is increased, and if the user slides in the
negative direction, the reproduction volume is decreased.
[0017]
The configuration of the optical slide 112 will be described with reference to FIGS. 2 (A) and 2
(B).
FIG. 2A is a top view of the optical slide 112, and FIG. 2B is a side view of the optical slide 112.
[0018]
As shown in FIG. 2A, the optical slide 112 is composed of light detection units 201A, 201B,
201C, and 201D.
Also, the top surface of the optical slide 112 is provided with a transparent window 204 for the
user to place a finger.
[0019]
08-05-2019
5
Each of the light detection units 201 (A, B, C, and D) includes a window 204 and a light emitting
element 202 (for example, an infrared LED (Light Emitting Diode)) that emits light 205 as
illustrated in FIG. The optical sensor 203 (for example, a photodiode or a phototransistor) which
receives the light 205 reflected by the finger and outputs a voltage signal having a voltage
proportional to the received light amount.
Each photosensor 203 outputs a voltage signal having a relatively large potential difference
according to the presence or absence of the reflected light to an A / D converter 109 and an
interrupt controller 108 described later via the selector 206.
Further, the light detection unit 201 outputs different voltages when receiving the reflected light.
[0020]
Specifically, for example, when the finger is placed on the light detection unit 201A, the light
sensor 203 of the light detection unit 201A outputs a voltage of 1.2 [V], and the light sensor 203
on the light detection unit 201B When the finger is placed on the light detection unit 201C, the
light sensor 203 of the light detection unit 201B outputs a voltage of 2.4 [V], and when the
finger is placed on the light detection unit 201C, the light detection unit 201C The light sensor
203 outputs a voltage of 1.8 [V], and when the finger is placed on the light detection unit 201D,
the light sensor 203 of the light detection unit 201 D has a voltage of 2.2 [V]. Output voltage.
However, any voltage is higher than a predetermined reference voltage of the selector 206
described later, for example, 0.9V.
Each light sensor 203 outputs a low voltage under a reference voltage of about 0.3 V, for
example, when not receiving the reflected light.
[0021]
The selector 206 has a plurality of input ends and one output end, and selects and outputs only a
08-05-2019
6
signal having a voltage equal to or higher than the reference voltage among voltage signals
supplied to the plurality of input ends.
In this example, from the relationship between the size of the light detection unit 201 and the
size of the finger, only one of the light detection units 201 outputs a signal having a voltage
higher than the reference voltage. If any input voltage signal is lower than the reference voltage,
the selector 206 outputs a predetermined voltage lower than the reference voltage level. The
selector 206 supplies the output voltage signal to the A / D converter 109.
[0022]
Further, the output of each light detection unit 201 is supplied to the interrupt controller 108
through the OR circuit OR. The OR circuit supplies a signal of logic “1” (active level) to the
interrupt controller 108 when the voltage of the voltage signal output from any of the light
detection units 201 becomes equal to or higher than the reference voltage.
[0023]
By the above processing, when the user places a finger on the optical slide 112, a voltage signal
equal to or higher than the reference level is output from any of the light detection units 201,
and the interrupt controller 108 is activated via the OR circuit OR. A signal is supplied, and an
interrupt signal is supplied to the CPU 105. As a result, the CPU 105 can perform the motion
detection operation of the user's finger. Furthermore, a voltage signal output from the light
detection unit 201 in a state in which the selector 206 detects a finger is selected and output.
This voltage signal is supplied to the CPU 105 via the A / D converter 109. Therefore, the CPU
105 that has started the finger detection operation by the interrupt signal can determine the
position of the finger from the output data of the A / D converter 109.
[0024]
Returning to FIG. 1, the control unit 101 includes a central processing unit (CPU) 105, an
interrupt controller 108, an A / D converter 109, a random access memory (RAM) 107, a read
only memory (ROM) 106, and an audio signal output unit 111. And a signal amplifier 110 and
the like. The CPU 105 controls the operation of the portable music apparatus 100 by
08-05-2019
7
appropriately executing various programs stored in the ROM 106. The CPU 105 also has an
internal timer.
[0025]
The interrupt controller 108 is connected between the CPU 105 and the operation unit 102,
receives an interrupt signal from the operation unit 102, and causes the CPU 105 to generate an
interrupt request signal. Further, after receiving the interrupt signal from the operation unit 102,
the interrupt controller 108 can perform control such as masking another interrupt signal for a
predetermined period.
[0026]
The A / D converter 109 converts the analog signal supplied from the operation unit 102 into a
digital signal and outputs it.
[0027]
The RAM 107 is used as a work memory when the CPU 105 executes a program.
[0028]
The ROM 106 is a read only storage device.
The ROM 106 stores information (programs) that does not need to be rewritten, such as the
volume control program 114, the equalizer setting program 115, the input code processing
application 116, the input processing driver 117, and the like.
[0029]
The volume control program 114 is a program for supplying a control signal corresponding to
the supplied signal to the signal amplifier 110 when the signal instructing the increase or
decrease of the reproduction volume is supplied from the operation unit 102.
08-05-2019
8
As a result, the reproduction sound output from the earphone 119 is adjusted.
[0030]
The equalizer setting program 115 is a program that can increase or decrease the volume of each
of several frequency bands of music data based on an instruction signal from the operation unit
102. Further, as shown in FIG. 3, the equalizer setting program 115 causes the display unit 104
to display an icon or the like using a GUI (Graphical User Interface) or the like, in order to clarify
the operation state or the like to the user.
[0031]
In the setting method of the equalizer, for example, when the display as shown in FIG. 3 is made
on the GUI, the user can adjust the volume by moving the knob indicated by the black square up
and down by operating the button switch 113 . FIG. 3 is a diagram when the volume of the
frequency band around 600 Hz is adjusted. In addition, it is possible to select which frequency
band to adjust the volume by operating the button switch 113.
[0032]
The input processing driver 117 generates an input code corresponding to the output signal
from the A / D converter 109. For example, when the finger is placed in the window 204 of the
light detection unit 201A, an input code "010" is generated, and when the finger is placed in the
window 204 of the light detection unit 201D, an input code "011" is generated. You may do it.
[0033]
The input code processing application 116 receives the input code generated by the input
processing driver 117, and determines the processing corresponding to the input from the
operation unit 102 based on the input code. As a result, operations corresponding to different
operations of the user in the operation unit 102 are executed. Specifically, for example, when the
operation unit 102, the A / D converter 109, the volume control program 114, the input
08-05-2019
9
processing driver 117, the input code processing application 116, and the CPU 105 cooperate
with one another, for example, the light detection unit 201B, light If the detection unit 201C and
the window 204 of the light detection unit 201D can be traced, the signal amplifier 110 is
controlled to increase the reproduction volume of music data.
[0034]
The audio signal output unit 111 includes a D / A converter that converts the music data read
from the storage unit 103 into an analog signal and outputs the analog signal. The audio signal
output unit 111 can also divide music data for each frequency band and output it.
[0035]
The signal amplifier 110 amplifies the music data (analog signal) read from the storage unit 103
to the audio signal output unit 111 at the amplification factor instructed by the control signal
given from the control unit 101 and outputs the earphone via the terminal 118 It is an analog
circuit which outputs to 119. In addition, when music data is divided for each frequency band
and supplied from the audio signal output unit 111, the signal amplifier 110 amplifies each
frequency band with the amplification factor set by the equalizer setting program 115, and The
signals for each band are added and output to the earphone 119.
[0036]
The storage unit 103 is configured of a storage device such as a hard disk drive.
[0037]
The display unit 104 is composed of a flat panel display such as a VFD (Vacuum Fluorescent
Display) or a liquid crystal monitor (LCD: Liquid Crystal Display), and is controlled by the control
unit 101 to make the operation status clear to the user. Display character strings and so on.
[0038]
The respective configurations of the first embodiment of the present system have been described
above.
08-05-2019
10
Next, the specific operation of the present apparatus having the above configuration will be
described with reference to the flowchart of FIG.
[0039]
FIG. 4 is a flowchart for explaining the equalizer setting calling process for calling the equalizer
setting program 115.
The equalizer setting call process shown in FIG. 4 is started by the interruption input by the
operation of the optical slide 112 disposed in the operation unit 102. Further, when the equalizer
setting call setting process is started by this interrupt input, the other interrupt input by the
operation of the optical slide 112 is not accepted until all the processes are completed.
[0040]
The CPU 105 of the control unit 101 determines how the optical slide 112 is operated when
there is an interrupt input. This is determined by the input code generated by the input
processing driver 117 as described above.
[0041]
First, the CPU 105 determines whether the light detection unit 201 on which the finger is placed
is the end of the optical slide 112 (the light detection unit 201A or the light detection unit 201D)
(step S101). Here, when it is determined that the finger is not placed at the end of the optical
slide 112 (step S101; No), the equalizer setting call process is ended as another process (step
S107).
[0042]
If it is determined in step S101 that a finger is placed on the end of the optical slide 112 (step
08-05-2019
11
S101; Yes), the CPU 105 activates an internal timer (step S102). Next, the CPU 105 determines
whether the optical slide 112 can be traced with a finger (step S103). Specifically, when the CPU
105 determines that the finger is placed in the window 204 of the light detection unit 201A in
step S101, the finger is in the window 204 of the light detection unit 201B disposed at the
position next to the light detection unit 201A. Whether or not the finger is touched is determined
depending on whether or not it is placed. If it is determined in step S101 that the finger is placed
in the window 204 of the light detection unit 201D, whether the finger is placed in the window
204 of the light detection unit 201C disposed at a position next to the light detection unit 201D.
It is determined whether or not the finger is touched.
[0043]
Here, when the CPU 105 determines that the light detection unit 201A has touched the window
204 of the light detection unit 201B with a finger (step S103; Yes), the reproduction volume of
the music data is increased (step S104). Specifically, a control signal for increasing the
amplification factor of music data, for example, by 5% is supplied to the signal amplifier 110.
When the CPU 105 determines from the light detection unit 201D that the area on the window
204 of the light detection unit 201C is touched with a finger (step S103; Yes), the reproduction
volume of music data is decreased (step S104). Specifically, a control signal for decreasing the
amplification factor of the music data, for example, by 5% is supplied to the signal amplifier 110.
Subsequently, the CPU 105 ends the equalizer setting call process.
[0044]
On the other hand, when the CPU 105 determines in step S103 that the optical slide 112 is not
touched by the finger (step S103; No), the optical slide 112 continues to be a finger until a
predetermined time (for example, 2 (sec)) elapses. The determination as to whether or not the
touch is performed is repeated (step S105; No, step S103).
[0045]
Here, when the CPU 105 determines that the predetermined time has elapsed (step S105; Yes),
the equalizer setting program 115 is developed in the RAM 107, and the equalizer setting
process is started (step S106).
Subsequently, the CPU 105 ends the equalizer setting call process.
08-05-2019
12
[0046]
After the equalizer setting process is started in step S106 described above, the audio signal of the
music data can be divided into several frequency bands to increase / decrease the sound volume
by a method equivalent to the prior art.
[0047]
The above equalizer setting calling process is performed in the control unit 101 of the portable
music apparatus 100 according to the first embodiment, so that the equalizer setting program
115 can be called by a simple operation without increasing the number of operation buttons. It
becomes possible.
In addition, since the switch frequently used as the volume switch is also used as the equalizer
setting call function, the portable music apparatus 100 according to the first embodiment can be
intuitively understood by the user without any problem in downsizing of the operation unit 102.
Realize easy operation.
[0048]
Second Embodiment In the first embodiment, the equalizer setting process is started by the
finger being placed at the end of the optical slide 112 for a predetermined period. However, in
the present invention, processing other than the equalizer setting processing may be started.
[0049]
For example, switching on / off of audio mute may be performed by placing a finger on the
window 204 of the light detection unit 201A or the window 204 of the light detection unit 201D
for a predetermined period.
[0050]
The portable music apparatus 100 of the second embodiment stores the mute control program
08-05-2019
13
120 in the ROM 106 described in the first embodiment, as shown in FIG.
The mute control program 120 supplies the mute control signal to the signal amplifier 110 so as
not to output the audio signal of the music data according to the instruction signal from the
operation unit 102 to set the amplification factor of the audio signal to 0 (audio mute Program).
Further, the mute control program 120 is a program for releasing the mute state when another
instruction signal is supplied from the operation unit 102.
[0051]
The CPU 105 executes the audio mute switching process shown in FIG. 6 by placing a finger on
the window 204 of the light detection unit 201A or the window 204 of the light detection unit
201D, and switches the audio mute on / off. .
[0052]
FIG. 6 is a flowchart for explaining the audio mute switching process.
The audio mute switching process is started by the interruption input by the operation of the
optical slide 112 disposed in the operation unit 102. Further, when the audio mute switching
process is started by this interrupt input, other interrupt inputs by the operation of the optical
slide 112 are not accepted until all the processes are completed.
[0053]
The CPU 105 of the control unit 101 determines how the optical slide 112 is operated when
there is an interrupt input. This is determined by the input code generated by the input
processing driver 117 as described above.
[0054]
First, the CPU 105 determines whether the light detection unit 201 on which the finger is placed
is the end of the optical slide 112 (the light detection unit 201A or the light detection unit 201D)
08-05-2019
14
(step S201). Here, when it is determined that the finger is not placed at the end of the optical
slide 112 (step S201; No), the audio mute switching process is ended as another process (step
S207).
[0055]
If it is determined in step S201 that a finger is placed on the end of the optical slide 112 (step
S201; Yes), the CPU 105 activates an internal timer (step S202). Next, the CPU 105 determines
whether the optical slide 112 can be traced with a finger (step S203). Specifically, when the CPU
105 determines that the finger is placed in the window 204 of the light detection unit 201A in
step S201, the finger is in the window 204 of the light detection unit 201B disposed at the
position next to the light detection unit 201A. Whether or not the finger is touched is determined
depending on whether or not it is placed. If it is determined in step S201 that the finger is placed
in the window 204 of the light detection unit 201D, whether the finger is placed in the window
204 of the light detection unit 201C disposed at a position next to the light detection unit 201D.
It is determined whether or not the finger is touched.
[0056]
Here, when the CPU 105 determines that the light detection unit 201A has touched the window
204 of the light detection unit 201B with a finger (step S203; Yes), the reproduction volume of
the music data is increased (step S204). Specifically, a control signal for increasing the
amplification factor of music data, for example, by 5% is supplied to the signal amplifier 110.
When the CPU 105 determines from the light detection unit 201D that the area on the window
204 of the light detection unit 201C is touched with a finger (step S203; Yes), the reproduction
volume of music data is decreased (step S204). Specifically, a control signal for decreasing the
amplification factor of the music data, for example, by 5% is supplied to the signal amplifier 110.
Subsequently, the CPU 105 ends the audio mute switching process.
[0057]
On the other hand, when the CPU 105 determines in step S203 that the optical slide 112 is not
touched by the finger (step S203; No), the optical slide 112 continues to be a finger until a
predetermined time (for example, 2 (sec)) elapses. The determination as to whether or not the
touch is performed is repeated (step S205; No, step S203).
08-05-2019
15
[0058]
Here, when determining that the predetermined time has elapsed (step S205; Yes), the CPU 105
develops the mute control program 120 in the RAM 107, and executes switching of audio mute
ON / OFF (step S206).
Specifically, when the CPU 105 determines that the finger is placed on the light detection unit
201A, the CPU 105 supplies a mute control signal for turning on the mute to the signal amplifier
110. When the CPU 105 determines that the finger is placed on the light detection unit 201D,
the CPU 105 supplies the signal amplifier 110 with a mute control signal to turn off the mute.
Subsequently, the CPU 105 ends the audio mute switching process.
[0059]
The audio mute switching process described above is performed by the control unit 101 of the
portable music apparatus 100 according to the second embodiment, so that the audio mute OFF
/ ON can be performed with a simple operation without increasing the number of operation
buttons. It is possible to switch. In addition, since the switch frequently used as the volume
switch is also used as the audio mute switching function, the portable music apparatus 100
according to the second embodiment can be intuitively understood by the user without any
problem in downsizing of the operation unit 102. Realize easy operation.
[0060]
Third Embodiment In the second embodiment, the audio mute switching process is started by the
finger being placed at the end of the optical slide 112 for a predetermined period. However, in
the present invention, processing other than the audio mute switching processing may be started.
[0061]
For example, the finger may be placed on the window 204 of the light detection unit 201A or the
window 204 of the light detection unit 201D, and the hold function of the volume switch may be
switched ON / OFF.
08-05-2019
16
[0062]
As shown in FIG. 7, the portable music apparatus 100 of the present embodiment stores the hold
control program 121 in the ROM 106 described in the first embodiment.
The hold control program 121 is a program that detects the current hold state and determines
whether to invalidate the switch operation according to the detected state and the instruction
signal from the operation unit 102. By executing the hold control program 121, the CPU 105 can
set the switch operation of the operation unit 102 to be valid / invalid. Also, the hold control
program 121 may be configured as hardware that realizes the same function as the hold control
program 121. Furthermore, the CPU 105 has a hold state flag for identifying the hold state.
[0063]
The CPU 105 of this embodiment executes the hold setting process shown in FIG. 8 by placing a
finger on the window 204 of the light detection unit 201A or the window 204 of the light
detection unit 201D for a predetermined period, and holds the volume switch hold function.
Switch on / off.
[0064]
FIG. 8 is a flowchart for explaining the hold setting process.
The hold setting process is started by the interruption input by the operation of the optical slide
112 disposed in the operation unit 102. In addition, when the hold setting process is started by
this interrupt input, other interrupt inputs by the operation of the optical slide 112 are not
accepted until all the processes are completed.
[0065]
The CPU 105 of the control unit 101 determines how the optical slide 112 is operated when
there is this interrupt input. This is determined by the input code generated by the input
processing driver 117 as described above.

[0066]
First, the CPU 105 determines whether the light detection unit 201 on which the finger is placed
is the end of the optical slide 112 (the light detection unit 201A or the light detection unit 201D)
(step S301). Here, when it is determined that the finger is not placed at the end of the optical
slide 112 (step S301; No), the hold setting process is ended as another process (step S309).
[0067]
If it is determined in step S301 that a finger is placed on the end of the optical slide 112 (step
S301; Yes), the CPU 105 activates an internal timer (step S302). Next, the CPU 105 determines
whether the optical slide 112 can be traced with a finger (step S303). Specifically, when the CPU
105 determines that the finger is placed in the window 204 of the light detection unit 201A in
step S301, the finger is in the window 204 of the light detection unit 201B disposed at the
position next to the light detection unit 201A. Whether or not the finger is touched is determined
depending on whether or not it is placed. If it is determined in step S301 that the finger is placed
in the window 204 of the light detection unit 201D, whether the finger is placed in the window
204 of the light detection unit 201C disposed at the position next to the light detection unit
201D. It is determined whether or not the finger is touched.
[0068]
Here, when the CPU 105 determines that the light detection unit 201A has touched the window
204 of the light detection unit 201B with a finger (step S303; Yes), the reproduction volume of
the music data is increased (step S304). Specifically, a control signal for increasing the
amplification factor of music data, for example, by 5% is supplied to the signal amplifier 110.
When the CPU 105 determines from the light detection unit 201D that the area on the window
204 of the light detection unit 201C is touched with a finger (step S303; Yes), the reproduction
volume of music data is decreased (step S304). Specifically, a control signal for decreasing the
amplification factor of the music data, for example, by 5% is supplied to the signal amplifier 110.
Subsequently, the CPU 105 ends the hold setting process.

On the other hand, when the CPU 105 determines in step S303 that the optical slide 112 is not
touched by a finger (step S303; No), the optical slide 112 continues to be a finger until a
predetermined time (for example, 2 (sec)) elapses. The determination as to whether or not the
touch is performed is repeated (step S305; No, step S303).
[0070]
Here, when the CPU 105 determines that the predetermined time has elapsed (step S305; Yes),
the hold control program 121 is expanded on the RAM 107, and the hold state flag is referred to
to detect the current hold state (step S306). ).
If the hold state flag referred to is 0 (OFF) (step S306; Yes), the hold state flag is set to 1 (ON).
Thereby, the switch operation is invalidated (the hold function is turned on) (step S307). On the
other hand, if the hold state flag referred to in step S306 is 1 (ON) (step S306; No), the hold state
flag is set to 0 (OFF). As a result, the switch operation is enabled (the hold function is turned off)
(step S308). Subsequently, the CPU 105 ends the audio mute switching process.
[0071]
By performing the above-described hold setting process in the control unit 101 of the portable
music apparatus 100 according to the third embodiment, the ON / OFF of the hold function can
be switched by a simple operation without increasing the number of operation buttons. It
becomes. In addition, since the switch frequently used as the volume switch is also used as the
hold setting function, the portable music apparatus 100 according to the third embodiment can
be intuitively understood by the user without any problem in downsizing of the operation unit
102. Realize easy operation.
[0072]
In addition, this invention is not limited to said each embodiment, A various deformation |
transformation and application are possible.

For example, in the first embodiment, the equalizer setting program 115 is activated by the
finger being placed at the end of the optical slide 112 for a predetermined period.
However, the present invention is not limited to this, and if it is a program related to sound
adjustment, a program capable of controlling and setting the sound quality such as loudness and
bass boost may be activated.
[0074]
Further, in the third embodiment, the finger is placed at the end of the optical slide 112 for a
predetermined period, thereby setting the invalidation / validity of the operation of all the
switches or keys provided in the portable music apparatus 100. . However, the present invention
is not limited to this, and it is not necessary to set all the switches. For example, it is also possible
to enable the hold function of volume up operation only that the user is surprised at erroneous
operation.
[0075]
Furthermore, in each of the above embodiments, the program related to sound adjustment is
activated depending on whether or not the finger is placed at the end of the optical slide 112 for
a predetermined period. However, the present invention is not limited to this, and it may be
determined whether or not a finger is placed at a central portion of the optical slide 112 for a
predetermined period, or whether the end of the optical slide 112 is touched twice with a finger
You may judge by no.
[0076]
Moreover, it is also possible to implement this invention combining said each embodiment. For
example, the first embodiment and the second embodiment may be implemented simultaneously.
In this case, it may be assigned to each function when the optical slide 112 is touched once as
described above and when it is touched twice. Specifically, when the end of the optical slide 112
is touched once, the embodiment 1 is performed, and when the end of the optical slide 112 is
touched twice, the embodiment 2 is performed. Just do it.

Furthermore, in each of the above embodiments, as shown in FIG. 2 (B), the optical slide 112
irradiates the finger 205 with light 205 from the light emitting element 202 such as an infrared
LED, and a photodiode according to the light amount , Etc. are converted into electrical signals.
However, the present invention is not limited to this, and the optical slide 112 may have any
structure or name as long as it can detect a finger tracing on the optical slide 112. For example, a
cavity resonator may be provided on the optical slide 112 and movement of a finger may be
detected by interference of optical waves, or a two-dimensional image (image) sensor or the like
is provided on the optical slide 112 to obtain continuously. The movement of the finger may be
detected by comparing the images (images).
[0078]
In each of the above-described embodiments, the method of determining that the finger is moved
on the window 204 of the optical slide 112 is that the finger is continuously placed on the light
detection units 201A and 201B or the light detection unit It was determined that the fingers
were continuously placed on the 201D and 201C. However, the present invention is not limited
to this, and the determination method is arbitrary as long as the movement of the finger traced
on the optical slide 112 can be detected. For example, it may be determined that a finger is
placed on the light detection units 201A, 201B, 201C, and 201D in succession, so that it may be
determined that tracing is performed, or two or more arbitrary light detection units 201 may be
continuously connected with a finger. It may be determined that it has been traced by being
placed.
[0079]
Furthermore, in each of the above embodiments, the program executed by the CPU 105 is stored
in advance in the ROM 106. However, the present invention is not limited to this, and the same
control as the control according to the above-described embodiment may be executable by
applying the program for executing the above-described processing to an existing portable music
apparatus. . A method for providing such a program is optional, and for example, it may be
provided via a communication medium such as the Internet, or may be distributed by being
stored in a recording medium such as a memory card.
