Piezoelectric sound device, game machine having the same, and sound system for game hall
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
piezoelectric acoustic device using a piezo speaker, a gaming machine provided with the
piezoelectric acoustic device, and an acoustic system for a game arcade. Conventionally, dynamic
type speakers are generally employed as acoustic devices for generating sound effects according
to the state of gaming, and the number of the speakers is, for example, stereo according to need.
When two are provided to generate sound, there is a problem that the same number of amplifiers
is also required and the cost is high. In addition, in the music source of sound effects, as a
method of giving a change to sound effects, it is only necessary to increase or decrease the sound

volume if it is one music, and it is necessary to prepare different musics for effective
presentation. Data will be increased. The costs involved are also a problem. [0003]
Conventionally, in the game arcade, speakers are installed at appropriate places in the stadium.
And, when it is necessary, in-game information is notified as an in-field announcement. Although
it is preferable to notify the contents targeted to all the players in the game arcade, there are
cases where the contents may be notified only to a limited area in the game arcade. For example,
there may be a case where it is intended to implement a service focused on players who are
playing on a specific gaming machine or slot machine base. In such a case, if there is no speaker
near the area, the player in the area would have to listen through the on-site speaker, and there
was a problem that it was difficult to hear. In addition, it is possible for the player outside the
area to hear information in the game arcade that is unnecessary, and to distract from
concentration on the game. Although a speaker may be provided for each area, the conventional
dynamic type speaker has a problem of cost because the number of amplifiers corresponding to
the number of speakers is required. [0004] The dynamic type speaker is composed of a magnet,
a coil, and a diaphragm, and has a structure for converting an audio frequency current to a sound
wave, and in this structure, a relatively large current is generated. Because of the cost, the
amplifier also required an expensive circuit. Furthermore, there is a restriction that the current
flowing through the coil does not flow more than the spec. Further, it is conceivable that this
dynamic type speaker generates a magnetic field by a magnet, and the magnetic field electrically
affects a control board or the like of the game machine to cause a malfunction. Therefore, in the
gaming machine using the conventional dynamic type speaker, there are many restrictions on the
selection of the mounting position of the speaker, and it can be mounted only at a limited
position.
As a solution to such a problem, for example, Patent Document 1 proposes a gaming machine
using a piezoelectric element type speaker instead of a dynamic type speaker. Since the
piezoelectric element type speaker does not use a magnet, it produces an effect of reducing the
electrical influence of the magnetic field to the control substrate etc. However, in this publication
technology, a plurality of speakers are effectively used and the amplifier is It did not solve the
cost problem by configuring without increasing the quantity. SUMMARY OF THE INVENTION
The present invention has been made in view of the above-described point, and a plurality of
speakers can be operated without increasing the number of amplifiers, and The amplifier itself
does not require an expensive circuit, and the operation of the speaker can be turned on and off
freely, and the piezoelectric acoustic device giving less load to surrounding electric parts, etc.,
and a game machine and a game equipped with the same It is in providing the sound system for
places. In order to solve the above-mentioned problems, in order to solve the above-mentioned
problems, a piezoelectric acoustic device according to the present invention comprises a
piezoelectric speaker consisting of a piezoelectric element such as a piezoelectric ceramic and
amplifying voice data. It is characterized by comprising an amplifier for outputting to a piezo
speaker, and a speaker control means for intermittently turning on / off the output of the

speaker. The piezoelectric element type speaker constituting the present invention has a
structure in which the voltage of an audio signal is converted to a sound wave by the so-called
reverse piezoelectric effect by utilizing vibration of piezoelectric ceramics or the like, and the
current is small due to its structure (10 several mA To vibrate and play the sound). In the case of
the structure using a magnet and a coil in the above-mentioned dynamic type speaker, when the
current flowing in the coil is turned on / off, a counter electromotive force is generated in the coil
and an overcurrent flows. Therefore, dynamic speakers can not be used to turn on and off. On
the other hand, piezo-type speakers do not have a magnet and coil structure, and even if the
sound being reproduced is suddenly cut off or the speaker line is suddenly turned on during
reproduction as described above. There is no current flow and can be turned on and off freely. By
using this feature, it is possible to reduce the cost of the audio device and to produce various
effects using sound effects. Further, according to the piezoelectric acoustic device of the present
invention, a plurality of piezo speakers made of piezoelectric elements such as piezoelectric
ceramics, and a plurality of piezo speakers for amplifying audio data and outputting the amplified
data to the plurality of piezo speakers are arranged in parallel. Between the common amplifier
connected and the common amplifier and the plurality of piezo speakers, provided in parallel
respectively corresponding to the respective piezo speakers, the output to all or a part of the
plurality of piezo speakers is And a switching transistor circuit as a speaker control unit that
turns on and off intermittently.
As a result, the on / off of the operation of the individual speakers is controlled, and it is possible
to generate sounds repeatedly and intermittently, to generate sounds in the on state, and to
generate no sounds in the off state. Become. Therefore, various different sounds are generated by
the combination of switching operation of a plurality of speakers, and various effects can be
produced using sound effects. The sound to be a source is voice data of one song, and it is
possible to generate different sounds of continuous sound and intermittent sound, and it is
possible to produce various sound effects, so the amount of audio data can be reduced. The
amplifiers can be configured by a common amplifier, and a plurality of speakers can be operated
by one amplifier, thereby achieving cost reduction. Further, in the piezoelectric acoustic device of
the present invention, the speaker control means further includes a drive circuit for driving the
switching transistor circuit on and off. The number of output ports is reduced, and additional
components can be configured relatively simply by connecting drive ICs. In the gaming machine
of the present invention, such a piezoelectric sound device, a display unit for displaying game
information, and command control for displaying a symbol according to the state of the game on
the display unit are performed. And a main control means for instructing and controlling the
speaker control means in conjunction with the display effect. [0015] Thereby, according to the
gaming state of the gaming machine, the combination of switching operation of the plurality of
speakers, intermittently generate sounds repeatedly, those that generate sound in the ON state,
and sounds in the OFF state Will not be able to occur. Therefore, a variety of different sounds can
be generated, the volume can be increased, or a combination thereof can produce a variety of
09-05-2019

effects using sound effects. Therefore, it is possible to contribute to enhancing the rendering
effect by generating different sound effects according to the display effect of the display unit of
the gaming machine, for example, at the time of reach of the so-called seven gaming machine
during the game. Further, in the audio circuit using the piezo speaker according to the present
invention, since a variety of sound effects can be produced only with audio data of one music, the
amount of audio data can be reduced. In addition, a plurality of speakers can be operated by one
amplifier, and the cost can be reduced. Furthermore, according to the sound system for a game
arcade of the present invention, a plurality of sound sources are provided to a piezoelectric
speaker installed corresponding to such a piezoelectric sound device and a gaming machine
group in which a plurality of gaming machines are arranged. And an input selection unit capable
of selective supply.
Alternatively, according to the sound system for a game arcade of the present invention, a
piezoelectric sound device having a plurality of piezo speakers, and all or a plurality of piezo
speakers installed for each gaming machine group in which at least a plurality of gaming
machines are arranged. And an output selection unit as a speaker control unit that intermittently
turns on / off an output to a part of the devices. According to these gaming room sound systems,
since the speaker control means is provided between the amplifier and the piezo speaker so as to
intermittently turn on or off all or part of the piezo speaker, The speakers can be driven
independently or easily driven entirely, and it becomes possible to broadcast information only to
the area where the audio data such as the information in the game arcade should be output. For
example, it is possible to carry out a guidance broadcast for implementing a service only in an
area where a specific gaming machine is installed. Also, for audio data, it is possible to select, for
example, a music CD, a wired broadcast or an in-store broadcast microphone, etc., and it is
possible to freely use it. Furthermore, the combination of sound source selection and piezo
speaker selection can provide the necessary information where it is needed. In addition, a
plurality of speakers provided in the game arcade can be operated by a common amplifier,
thereby reducing costs. In addition, since the piezo speaker is lighter than the dynamic speaker, it
is not necessary to reinforce the mounting portion at the time of mounting, and the degree of
freedom of installation is high. A simple and inexpensive game room audio system can be
realized. Further, when a piezo speaker is installed at, for example, a resting place or a childcare
place other than the installation place of the gaming machine, it becomes possible to broadcast
information only to such place. It should be noted that the piezoelectric acoustic device of the
present invention can be provided in a game machine installed in these game arcades. At that
time, it is also possible to drive a plurality of piezo speakers provided in the game machine and
the game arcade with a common amplifier, and in this case, the cost of the game machine and the
game arcade can be reduced. Centralized sound management becomes possible. BEST MODE FOR

ball supply tray 4 are shot toward the game board 3 by a ball firing mechanism including the
handle 5. Since a large number of nails are bored in the game board 3, the balls reaching the
game board 3 through the rails are dropped while being knocked by those nails (the nails are not
shown). A liquid crystal display unit 6 (variable display unit) is disposed in the vicinity of the
center of the game board 3. A display device using a light emitting element or a reel type display
device can also be adopted. The liquid crystal display unit 6 displays, for example, three-digit
Arabic numerals. A start chucker 7 (start gate) is disposed below the liquid crystal display unit 6.
Below the start chucker 7, an attacker 8 (large winning opening) that opens when the pachinko
gaming machine 1 makes a big hit, and an out port 9 for collecting balls are provided. Piezo
speakers 10a, 10b, 10c, and 10d are provided on the front, upper, lower, left, and right sides of
the underframe of the gaming machine 1, respectively. This type of speaker may be configured
as a unit having a speaker box as a resonator that generates a sound by resonating with a
piezoelectric vibrator made of piezoelectric ceramic, or, for example, directly attached to a frame,
instead of the speaker box Thus, the frame can be made to generate sound as a resonating body.
Various types of sounds can be produced depending on the type of resonator. In the present
invention, the speaker may have a resonator, or the frame itself may be a resonator, regardless of
the configuration of the resonator, these are collectively referred to as a piezo speaker. The
mounting position of the piezo speaker 10 may be attached to the surface of the inner game
board 3 as another embodiment. The piezo speaker 10 has a feature of freedom of arrangement
and does not choose an installation place. Next, FIG. 2 is a block diagram showing the
configuration of the game control apparatus 20 of the pachinko gaming machine 1. Such a game
control device 20 is disposed on the back side of the game board 3. As shown in FIG. 2, the
gaming control device 20 of the pachinko gaming machine 1 includes a main board 21 (main
control unit), a display board 22 (display control unit), an audio board 23 (audio control section),
and a lamp board 24 (lamp The control unit is configured to include a delivery board 25 (a prize
ball control unit) and a launch board 26 (a launch control unit). A configuration in which each
substrate individually includes a CPU and a memory is general, but is omitted in FIG.
Further, power of a predetermined voltage generated by the power supply circuit unit 27 is
supplied to each substrate. The display substrate 22 executes a process for displaying an image
on the liquid crystal display unit 6 in accordance with a display control signal input from the
main substrate 21. The audio substrate 23 causes the piezo speaker 10 to output audio in
accordance with the input audio control signal. The lamp substrate 24 controls the blinking of
the lamps 11 in accordance with the input lamp control signal. The payout board 25 controls the

payout device 12 in accordance with the received winning ball signal. As a result, a
predetermined amount of winning balls are paid out to the player. The launch board 26 actuates
a launch device 13 provided corresponding to the handle 5 in response to the player operating
the handle 5 (operation unit). The main board 21 is provided with a CPU 14, a ROM 15 for
storing a program, a RAM 16 for work, and an input / output port 17. These communicate with
one another via a bus. Note that the display substrate 22, the audio substrate 23, and the lamp
substrate 24 may be combined into one substrate, or may be configured as a liquid crystal /
voice / lamp substrate 50. The main substrate 21 is electrically connected to the start chucker 7
and a prize detection unit 18 attached to the attacker 8. Such a prize detection unit can be
configured by a contact or non-contact sensor (switch). Further, the opening and closing of the
attacker 8 configured as the variable winning prize opening is realized by switching the
excitation / non-excitation of the attack solenoid 19. When a ball is won in the start chucker 7
and the attacker 8, a prize detection signal is generated in the prize detection unit 18. The CPU
14 of the main board 21 acquires a start winning detection signal from the start winning
detection unit 18, and executes predetermined electrical processing in accordance with the signal
acquisition timing (input timing). The electrical process is a lottery process for determining
whether or not to cause the pachinko gaming machine 1 to generate a big hit, and the liquidation
result 6 (lead or miss) in the lottery process is derived and displayed on the liquid crystal display
unit 6 Includes display processing. Specifically, a lottery process for determining whether or not
to generate a jackpot is executed, and based on the result of the lottery process, a symbol to be
displayed on the liquid crystal display 6 is determined. A display control signal (control
command) based on the determination is input to the display substrate 22.
The display substrate 22 causes the liquid crystal display unit 6 to display a symbol, a
background, and the like in accordance with the input display control signal. When it is
determined that the jackpot is to be generated by the lottery process, the liquid crystal display
unit 6 displays the jackpot symbol (e.g., a scorpion such as "777") after the fluctuation of the
symbol for a predetermined time. It becomes. Similarly, each control board executes control
based on a control signal (control command) transmitted from the main board 21 with respect to
sound output and blinking of a lamp. A program for performing such control is stored in the
ROM 15 of the main board 21 and the ROM (not shown) of each control board. Next, FIG. 3 is a
block diagram showing the configuration of the sound board 23 of the pachinko gaming machine
1. As shown in FIG. 3, the voice board 23 of the pachinko gaming machine 1 includes a CPU 30
(voice board CPU), a ROM 31 (voice board ROM), a RAM 32 (voice board RAM), a voice LSI 33, a
voice data ROM 34, and an amplifier 35. , The line switching circuit unit 36, the drive IC 37, and
the piezo speakers 10a, 10b, 10c, and 10d. The switching circuit section 36 is composed of pnp
transistors 38a, 38b, 38c and 38d and resistors 39a, 39b, 39c and 39d. The CPU 30 is
configured to receive a signal of the main board 21. Execution of control of the voice board 23 is
performed based on a control signal (control command) transmitted from the main board 21. The
audio LSI 33 takes in the audio data of the audio data ROM 34 according to the audio control
09-05-2019
6
signal input from the CPU 30, amplifies it by the amplifier 35, and outputs the audio from the
speaker 10. The switching circuit 36 of the line is disposed between and connected to the line
between the amplifier 35 and the speakers 10a, 10b, 10c and 10d, and receives a signal from the
CPU 30, and an input signal to the transistors 38a, 38b, 38c and 38d. Are driven and controlled
by the drive IC 37, thereby controlling on / off of the operation of the speakers 10a, 10b, 10c
and 10d. That is, in the initial setting, the transistor 38 is in the on state, and the speaker 10 is in
the on state. Next, the transistor 38 is turned off by turning the base voltage to zero with the
input signal, and the speaker 10 is also turned off. Next, when a voltage is applied to the base by
the input signal, the transistor 38 is turned on, and the speaker 10 is also turned on.
While driving the speaker, cut off this output, repeat off-on-off, and control the input signal
applied to the base of the transistor so that the speaker emits sound intermittently at a
predetermined interval. Control the on / off of the transistor. As described above, the transistor is
used as a switch to control on / off of the operation of the speaker. By intermittently supplying
the input signal, the speaker 10 generates intermittent repetitive sounds. Thus, the switching
circuit using the transistor is provided in parallel between the amplifier 35 and each of the piezo
speakers 10a, 10b, 10c, 10d in parallel to the piezo speakers 10a, 10b, 10c, 10d being driven.
The sound output is generated by intermittently cutting off the output of. That is, the speakers
10a, 10b, 10c, and 10d are controlled to turn on and off individually according to the input
signal, and the speakers 10a, 10b, 10c, and 10d intermittently generate sounds repeatedly, or
generate sounds in the on state, and in the off state. You will be able to do something that
produces no sound. Therefore, various different sounds can be generated by a combination of
switching operations of the speakers 10a, 10b, 10c and 10d. Moreover, a variety of sounds can
be generated with one music source. The drive IC 37 is provided for the purpose of driving and
controlling a plurality of channels. This method has a small number of output ports of the CPU
30, and has the advantage that the circuit can be configured relatively simply by connecting the
drive IC 37 as an additional component. is there. In addition, a method is also possible in which
the drive IC 37 synchronizes all the speakers in common to make a sound. This has the effect of
making the sound clearer. The present invention is not limited to this, and a configuration in
which signals are directly sent from the CPU 30 to the transistors 38a, 38b, 38c and 38d may be
used without providing the drive IC 37 in the middle. Also, the transistor 38 can be configured as
a mute type (a silent state at the initial setting) as the npn-type transistor 38 as another
embodiment (details of the circuit configuration are not shown). Next, with respect to control of
one of the piezo speakers 10, an embodiment shown in FIG. 4a will be described. Using a single
speaker, first make a sound (the first reach is applied), and in the next stage, turn the speaker off
and on repeatedly to make the tonal sound add to the presentation effect It can be enhanced.
Also, in FIG. 4b, the volume of the speaker is first lowered and the sound is made to flow by the
amplifier 35 (in a state where the initial reach is applied), and the volume of the speaker is
09-05-2019

gradually raised at the next stage to enhance the rendering effect. An example is shown. Next, an
embodiment of switching control of a plurality of piezo speakers 10 will be described based on
Table 1. [Table 1] <img class = "EMIRef" id = "198607365-000003" /> According to the game
state of the gaming machine 1, ie, the display of the liquid crystal display unit 6 of the gaming
machine 1 When the so-called reach state is displayed, the speakers 10a, 10b, 10c and 10d
which output voices in the pattern shown in Table 1 above are selected and switched. That is, the
number of speakers to be turned on is increased from the state of reach 1 where the frequency
of occurrence is high to the state of reach 4 where the frequency of occurrence is low, or the on /
off is repeated intermittently. By repeating on and off intermittently, the tonality is added to the
sound, thereby generating various sound effects and enhancing the reach effect effect (see FIG.
5a). Specifically, when the reach is initially applied, the speakers 10a and 10b are on, 10c and
10d are off (reach 1), and the speakers 10a and 10b are on at the next stage. 10c and 10d are
repeatedly turned on and off intermittently, and the sound is superimposed and raised with
different sound effects (reach 2 state). In the next step, with 10c and 10d repeating ON and OFF
intermittently, the speakers 10a and 10b are also intermittently repeated, and the toning sound
is further enhanced to enhance the rendering effect (the state of reach 3) ). Furthermore, at the
final stage, all the speakers 10a, 10b, 10c and 10d are turned on to increase the volume to
produce a climax state (reach 4 state). Thus, the sound data from the sound data ROM 34 can
generate various sound effects with only one song. The program for switching control is stored in
the ROM 31. It is temporarily stored in the RAM 32 at the time of reach. The switching control of
the piezo speaker 10 according to the present invention is not limited to the above-described
reach state, but at any time widely, the piezo speaker 10 is intermittently and repetitively
supplied with a signal that repeatedly turns on and off. By generating a sound, it can be used for
various effects (see FIG. 5b).
Note that one speaker 10 may be monaural, or two speakers 10 may be configured as stereo.
Furthermore, it may be configured to connect to the voice LSI 33 by switching the input with the
individual music CD 33 'at the front stage of the amplifier 35 in the voice substrate 23 as a
source. . Although the speaker 10 is configured by four, it is also possible to configure by
increasing this number, and the amplifier 35 can be configured without increasing (details of the
circuit configuration are not shown). As described above, the present invention is described using
a pachinko gaming machine as an example, but it is also possible to replace it with a sound
device in a slot machine or another game machine. Second Embodiment Next, a second

island, for example, the ceiling above the gaming machine located at the center of the island.
Next, FIG. 7 is a block diagram showing the configuration of the in-store broadcast control
apparatus 66. As shown in FIG. The audio data generation unit 67 includes an input interface 71
(input selection unit), a selector unit 72 (input selection unit) connected to the input interface 71,
and an amplifier 35 to which the output of the selector unit 72 is connected. ing. An in-store
broadcast microphone 73, a music CD 33 ', and a wired broadcast 74 are connected to the input
interface 71 as audio data. These voice data are selected by the selector unit 72. Further, the
output of the hall computer 60 is connected to the input interface 71. The switching means 68

The input user interface 75 has, for example, a keyboard of a personal computer and has a
function of selecting and inputting a required island of the guide broadcast. Control of the instore broadcast control apparatus 66 is performed based on a control signal transmitted from the
CPU 61 of the hall computer 60. Based on the control signal, the selector unit 72 selects and
takes in the audio data of the music CD 33 ', the cable broadcast 74 or the in-store broadcast
microphone 73, amplifies it by the amplifier 35, and outputs the audio to the piezo speakers 10a
to 10l. A switching circuit unit 36 is disposed between and connected to the line between the
amplifier 35 and the speakers 10a to 10l, receives a signal from the input user interface 75, and
receives an input signal to the transistors 38a to 38l by the drive IC 37. The drive control is
performed to control the on / off of the operation of the piezo speakers 10a to 10l. That is, in the
initial setting, the transistors 38a to 38l are in the on state, and the piezo speakers 10a to 10l are
in the on state. Next, by making the base voltage zero with the input signal, the transistors 38a to
38l are turned off, and the piezo speakers 10a to 10l are also turned off. When a voltage is
applied to the base by the next input signal, the transistors 38a to 38l are turned on, and the
speakers 10a to 10l are also turned on. During driving of the speaker, the input signal applied to
the base of the transistor is controlled to control on / off of the transistor. Thus, the transistor is
used as a switch to control the on / off operation of the speaker. By the selection input in the
input user interface 75, it is possible to drive the piezo speakers 10a to 10l individually and
independently. As shown in Table 3, broadcast contents are set. <Img class = "EMIRef" id =
"198607365-000005" /> [0049] Necessary speakers among the piezo speakers 10a to 10l
according to the broadcast code selected by the input user interface 75 Only (Speakers installed
on the island where guidance is required) are driven. For example, in the case of the broadcast
code "1", the type code "ALL" and the model code "ALL" are set, and all of the piezo speakers 10a
to 10l are driven. For example, it is possible to play music from the music CD 33 'or to call the
entire building with the in-store broadcasting microphone 73.
In the broadcast code "2", the type code "P1" and the model code "ALL" are set, and all of the
"seven machines (type code P1)", therefore, the speakers 10a to 10f installed on the islands A to
F Only in the in-store broadcasting microphone 73, it is possible to broadcast a guidance
broadcast in the case of implementing a service intended for a player who is playing a game with
"seven machines". As a service, for example, a fixed amount of bonus (usually hitting once a
jackpot or trying to replace the ball, or the store's sales policy is taken, but a bonus that allows
you to continue playing with the jackpot) is awarded Services are listed. For broadcast code
“3”, set to type code “P2” and model code “ALL”, and for broadcast code “4”, set to
type code “P1” and model code “001”, broadcast code “5” Then, set the type code "P1"
and the model code "002", set the type code "S" and the model code "ALL" for the broadcast code
"6" and the type code "S" for the broadcast code "7" It is set to the model code "006 & 007". For
example, as in the case of the broadcast code "4", for the guidance broadcast in the case where
the service is implemented only for the model code "001" with the type code "P1", that is, only

some models among the "seven machines". It can correspond. The transistors 38a to 38l can be
configured as a mute type (in a silent state at the initial setting) as the npn type transistor 38 as
another embodiment. Also, the input user interface 75 may be configured by a mechanical switch
instead of the keyboard. In this manner, notification can be made only to the area to which voice
data such as game arcade information should be output. For example, it is possible to carry out a
guidance broadcast for implementing a service only in an area where a specific gaming machine
is installed. A plurality of speakers provided in the game arcade can be operated by a common
amplifier, and cost can be reduced. In addition, the piezo speaker is excellent in durability
because there is no performance deterioration due to magnetic force deterioration as in the
dynamic speaker, and it is excellent in water resistance because cone paper is not used.
Furthermore, since it is lightweight compared to a dynamic speaker, there is no need to reinforce
the mounting portion at the time of mounting, and the degree of freedom of installation is high. A
simple and inexpensive in-game sound system can be realized. Further, when a piezo speaker is
installed at, for example, a resting place or a childcare place other than the installation place of
the gaming machine, it becomes possible to broadcast information only to such place.
Note that the piezoelectric acoustic device of the present invention can be provided in a game
machine installed in a game arcade. At that time, it is also possible to drive a plurality of piezo
speakers provided in the game machine and the game arcade with a common amplifier, and in
this case, the cost of the game machine and the game arcade can be reduced. Centralized sound
management becomes possible. Further, the speaker control means (specifically, the switching
circuit unit 36, the drive IC 37, the input user interface 75) generates control signals based on
control signals from others (for example, the hall computer 60) or by itself. By intermittently
supplying the input signal, the piezoelectric speakers 10a may be configured to generate
intermittent repetitive sounds. The piezoelectric speakers 10a,..., The amplifier 35, the switching
circuit unit 36 as a speaker control means, the drive IC 37, etc., which are described in common
in the first embodiment and the second embodiment, are piezoelectric type according to the
present invention. Configure an acoustic device. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1
