The present invention relates to a panel-integrated audio output device including a display panel
for displaying a predetermined image, and an excitation means for vibrating the display panel to
output sound.
[0002]
2. Description of the Related Art Conventionally, an image and sound output device such as a
11-05-2019
1
television receiver and a display connected to a PC (Personal Computer) or the like is known.
Such an image / sound output device includes a display unit such as a liquid crystal panel and an
organic EL (electroluminescence) panel for displaying an image according to the image signal
among the input image signal and sound signal, and the sound signal. And an audio output unit
such as a speaker for outputting the selected audio. However, in such an image / sound output
device, since the image display means and the sound output means are individually provided, an
increase in the number of parts is caused, which leads to an increase in manufacturing cost, and
an image / sound output device There is a problem of upsizing.
[0003]
On the other hand, a configuration has been proposed in which sound is output by vibrating a
cover glass that covers a liquid crystal panel as an image display unit. However, in such a
configuration, the gap formed between the cover glass and the liquid crystal panel causes
reflection of external light and reflection of an image, resulting in a problem of deterioration of a
displayed image. In order to solve this problem, a filler may be enclosed in the gap, the cover
glass and the liquid crystal panel may be integrated, and these may be vibrated. In such a
configuration, it should function as a diaphragm. The cover glass alone can not be vibrated, and
even if the entire image display means is vibrated, there is a problem that a large driving force is
required for sound output.
[0004]
On the other hand, a speaker integrated type display device is known which employs a
lightweight organic EL panel as an image display means and outputs sound by vibrating the
organic EL panel (see, for example, Patent Document 1). In the display device described in Patent
Document 1, sound is output by vibrating the organic EL panel with an excitation device
configured of a movable coil and a magnet. With such a configuration, it becomes unnecessary to
separately provide a speaker, so that the manufacturing cost of the display device can be
reduced, and the display device can be miniaturized. In addition, since image display and audio
output are performed in the same area, images and audio can be viewed without discomfort.

[0006]
However, in the display device described in Patent Document 1, since the organic EL panel as the
diaphragm is vibrated by the movable coil and the magnet, it is possible to output a large volume,
but there is a problem that the power consumption is large. .
[0007]
An object of the present invention is to provide a panel-integrated audio output device capable of
achieving power saving.
[0008]
In order to achieve the above-mentioned object, the audio output device of the present invention
comprises a display panel for displaying a predetermined image, and a panel integrated type
comprising an excitation means for vibrating the display panel to output sound. The audio output
device, wherein the display panel is formed of an organic EL panel, the exciter means forms an
enclosed portion that encloses a fluid therein, and a part of the enclosed portion, and the
enclosed portion Micropart having an enclosing body having a displacing portion which can be
elastically displaced toward the inside of the part, and a piezo which is provided according to the
enclosing body and elastically displaces the displacing portion to vibrate the organic EL panel A
plurality of pumps are provided.
[0009]
According to the present invention, the organic EL panel which is a display panel can be vibrated
by driving each piezo to displace the enclosure.
According to this, the organic EL panel can be used as a diaphragm, and sound can be output by
the organic EL panel.
Here, the power consumption for driving the piezo is smaller than the power consumption for
vibration of the coil.
In addition, the organic EL panel is lighter and thinner than a liquid crystal panel that needs a
11-05-2019

backlight for image formation.
For this reason, the driving force required for the vibration of the organic EL panel does not have
to be large, and the organic EL panel can be sufficiently vibrated even by the drive of the piezo.
Therefore, power consumption related to audio output can be reduced, and power saving of the
panel-integrated audio output device can be achieved.
[0010]
In the present invention, the excitation means covers one end face of each of the enclosures and
elastically displaces on the opposite side to the enclosure in response to a pressure change of the
fluid due to the elastic displacement of the displacement portion. An elastic member is provided,
and the elastic member is provided with a contact portion which is provided on a surface of the
elastic member facing the organic EL panel and which contacts the organic EL panel, and the
contact portion is the elastic member. Preferably, the hardness is higher than that of the member
and the cross-sectional area is smaller than that of the elastic member.
[0011]
According to the present invention, a plurality of micro pumps can be integrated by an elastic
member, whereby the apparent cylinder diameter can be increased.
According to this, the displacement force generated by the displacement of each micro pump and
transmitted to the organic EL panel can be increased. This displacement force can be transmitted
to the organic EL panel at one point of the contact portion. Therefore, it is possible not only to
reliably vibrate the organic EL panel, but also to increase the amplitude of the organic EL panel.
[0012]
In the present invention, a piezo control unit that controls the drive of each of the piezos based
on an input audio signal is provided, and the piezo control unit is configured to control the piezo
according to the frequency of the audio output based on the audio signal. It is preferable to drive
a plurality of piezos sequentially. According to the present invention, since each piezo is
individually controlled by the piezo control unit and each piezo is sequentially driven according
to the frequency of the sound to be output, the displacement force of the micro pump generated
11-05-2019
4
by the displacement of each piezo is It is transmitted to the organic EL panel at different timings.
According to this, the vibration frequency of the organic EL panel can be increased. Therefore,
high frequency sound can be output with certainty.
[0013]
In the present invention, a piezo control unit that controls the drive of each of the piezos based
on an input audio signal is provided, and the piezo control unit has a number corresponding to
the volume of the audio to be output based on the audio signal. Preferably, the piezos are driven
substantially simultaneously. According to the present invention, the displacement force of each
micro pump generated by the displacement of the plurality of piezos is simultaneously
transmitted to the organic EL panel. According to this, since the amplitude of the organic EL
panel can be further increased, the volume of the output can be increased. Therefore, large
output of voice (voice output at large volume) can be reliably performed.
[0014]
In the present invention, the organic EL panel is provided in the vicinity of intersections of a
plurality of scanning lines and a plurality of signal lines substantially orthogonal to each other,
the plurality of scanning lines and the plurality of signal lines, A substantially rectangular panel
main body having a plurality of pixels emitting light according to the voltage applied by the
signal line, a first applying means for applying a voltage to the plurality of scanning lines, and a
voltage to the plurality of signal lines And a second application means for applying, wherein the
first application means and the second application means are disposed along each of the
mutually crossing sides of the panel body, and the excitation means is provided diagonally on the
panel body And it is preferable to vibrate using the vicinity of the corner on the opposite side to
the corner where the above-mentioned sides cross as a starting point.
[0015]
According to the present invention, since the excitation means is disposed avoiding the first
application means and the second application means, voltage application to the scanning line and
the signal line by the first application means and the second application means is hindered. Can
be prevented.
Therefore, the image display by the organic EL panel can be reliably performed. In addition, since the excitation
11-05-2019
5
means is provided in the vicinity of the corner of the panel body, the excitation means abuts in the vicinity of the
corner of the panel body. According to this, since the vibration of the panel body generated by the excitation
means is generated with the vicinity of the corner as a base point, the vibration can be easily propagated to the
entire panel body. Therefore, sound can be output reliably from the entire surface of the panel body.

[0026]
FIG. 5 is a schematic view showing the configuration of the micro pump 61. As shown in FIG. Among these,
FIG. 5 (A) shows a state in which the micro pump 61 is not driven (displaced), and FIG. 5 (B) shows a state in
which the micro pump 61 is driven (displaced) . The micro pump 61 presses the elastic member 62 to elastically
displace it. The micro pump 61 is an improvement of a micro pump used for a printer head of an ink jet printer,
and as shown in FIG. 5, a substantially rectangular solid enclosure 611 and a piezo 612 attached to the enclosure

FIG. 6 is a block diagram showing the configuration of the control means 7. The control means 7 controls the
video / audio output device 4 based on a command input from the control device 9 which controls the entire
gaming machine 1. Specifically, the control means 7 controls the drive of the organic EL panel 5 to form and
display an image according to the command, and controls the drive of the vibration exciter 6 to output a voice
according to the command. Let The control unit 7 is configured as a circuit board on which a CPU, a memory,
and the like are mounted, and a command acquisition unit 71, an image forming unit 72, a panel control unit 73,
and an audio generation unit 74 realized by these circuit elements. , A piezo control unit 75 and a storage unit 76.
[0030]
Among these, although not shown in detail, the storage unit 76 is configured by a program ROM (Read Only
Memory), a work RAM (Random Access Memory), a CGROM (Character Generator ROM), a VRAM (Video
RAM), and the like. Among them, the program ROM stores various programs and data (including encoded
audio data) necessary for processing in the control means 7, and the work RAM stores at least a part of the
program and data in the processing. Do. Further, the CGROM stores partial image data such as characters
relating to a display image, and the video RAM stores image data corresponding to one frame.
[0031]
The command acquisition unit 71 acquires a command input from the control device 9. Then, when the
acquired command is a drawing command, the command acquiring unit 71 outputs a control signal for forming
and displaying an image according to the drawing command to the image forming unit 72, and the acquired
information When the command is an audio output command, a control signal for outputting an audio
according to the audio output command is output to the audio generation unit 74. The image forming unit 72
acquires partial image data from the CGROM of the storage unit 76, and generates, on the VRAM, image data
corresponding to the input control signal. The panel control unit 73 includes a dot clock terminal, an Hsync
terminal, a DE terminal, a Vsync terminal, and a pixel data terminal, and via the respective terminals, a drive
signal for driving the panel main body 51, A pixel data signal corresponding to each pixel is output to the panel
main body 51. The sound generation unit 74 generates sound data corresponding to the input control signal with
reference to the storage unit 76 described above.
[0032]
The piezo control unit 75 applies a voltage as a drive signal to the piezo 612 based on the generated audio data. At
this time, the piezo control unit 75 applies a voltage to the plurality of piezos 612 at predetermined time intervals
11-05-2019
10
in accordance with the frequency of the sound based on the sound data. As a result, the excitation device 6 can be
driven at a high frequency, and the panel body 51 vibrates at the frequency, so that high frequency sound can be
output. In the present embodiment, the piezo control unit 75 applies a voltage to each of the piezos 612 so that
the piezos 612 can be driven at a drive frequency of 45 kHz at maximum.
[0033]
Also, the piezo control unit 75 simultaneously applies a voltage to the plurality of piezos 612 according to the
volume of the sound based on the generated sound data. As a result, since the plurality of micropumps 61 are
displaced at the same time, the amplitude of the elastic member 62 is increased, and the amplitude of the panel
main body 51 is increased accordingly. Therefore, it is possible to output a large amount of sound from the panel
body 51 (sound output of a large volume).
[0034]
According to the gaming machine 1 of the present embodiment described above, the following effects can be
achieved. (1) The displacement of each of the piezos 612 and the displacement of the enclosure 611 provided
with the piezos 612 generates a displacement force that causes the panel body 51 to vibrate. According to this,
sound can be output using the panel body 51 as a diaphragm. Here, since the power consumption of the piezo
612 is smaller than the power consumption of the driving means such as a coil, and the panel main body 51 is
lighter and thinner than the liquid crystal panel, the power consumption of the panel main body 51 is reduced.
Can be vibrated reliably. Therefore, it is possible to configure a panel-integrated image / sound output device 4
for saving power. In addition, since such a vibration exciter 6 can be configured by improving a part of the
printer head of an inkjet printer distributed in the market, it can be configured easily and inexpensively, and in
turn, the image / sound output device The manufacturing cost of 4 can be reduced. Furthermore, since the
assemblability and decomposability of the image and sound output device 4 with respect to the game board 31 is
excellent, reuse and recycling of the image and sound output device 4 can be easily performed, and an
environment-friendly configuration can be provided. it can.
[0035]
(2) The opening 6112 side of the plurality of micropumps 61 is closed by the elastic member 62, and the
micropumps 61 are integrated by the elastic member 62. According to this, the cylinder diameter of the vibration
exciter 6 can be increased, and the displacement force generated by the displacement of each micro pump 61 can
be increased. Therefore, by transmitting the displacement force to the panel main body 51 at one point of the
11-05-2019
11
contact portion 63, the panel main body 51 can be reliably vibrated. Moreover, thereby, the amplitude of the said
panel main body 51 can be enlarged, and an audio | voice can be output reliably.
[0036]
(3) The piezo control unit 75 individually controls each piezo 612 based on the generated voice data. According
to this, by sequentially driving each of the piezos 612 at different timings, the vibration frequency of the organic
EL panel can be increased, and high frequency sound can be output.
[0037]
(4) The piezo control unit 75 can simultaneously displace the plurality of piezos 612 and simultaneously transmit
the displacement force generated by the plurality of micro pumps 61 to the panel main body 51. According to
this, the amplitude of the panel body 51 can be increased, and a large output of sound (sound output at a large
volume) can be reliably performed.
[0038]
(5) Since the vibration exciter 6 is arranged in the panel main body 51 so as to avoid the end portion side where
the Y driver 52 and the X driver 53 are provided, scan lines and signal lines by the Y driver 52 and the X driver 53
are provided. It is possible to prevent the voltage application, that is, the driving of the panel body 51 from being
disturbed. Further, since the vibration exciter 6 is provided on the back side near the corner of the panel main
body 51, the contact portion 63 of the vibration exciter 6 is brought into contact in the vicinity of the corner of
the panel main body 51. Can. According to this, the vibration of the panel main body 51 generated by the
vibration exciter 6 can be easily propagated to the entire panel main body 51 starting from the vicinity of the
corner. Therefore, the sound can be reliably output from the entire surface of the panel main body 51.
[0039]
(6) Since the gaming machine 1 includes the above-described image / sound output device 4, it is not necessary
to separately provide a speaker or the like in the gaming machine 1. According to this, the manufacturing cost of
the gaming machine 1 can be reduced. Also, when an image is displayed, the player tends to gaze at the image.
Therefore, by using the panel body 51 for displaying the image as a diaphragm to output sound, the player's ear
11-05-2019
12
can be naturally directed to the sound output source. Therefore, the voice to be output can be made easy to hear.
Further, since the small-sized organic EL panel 5 can be configured as a speaker, the small-sized image / sound
output device 4 can be disposed in non-playing areas (not shown) at the four corners of the game board 31.
Thus, video and audio can be output at the four corners, and the interest of the player can be increased.
Furthermore, by tilting the video / audio output device 4 disposed in the non-playing area toward the player, the
directivity of video and audio can be enhanced.
[0040]
〔2. Second Embodiment] Next, a second embodiment of the present invention will be described. The
gaming machine according to the present embodiment has the same configuration as the gaming machine 1
described above. However, in the gaming machine 1, the vibration exciter 6 is disposed on the back side of the
panel main body 51. In the gaming machine of the present embodiment, the gaming machine and the gaming
machine 1 are different in that the vibration damping device is arranged on the side of the panel main body 51. In
the following description, parts that are the same as or substantially the same as the parts described above are
given the same reference numerals and descriptions thereof will be omitted.
[0041]
FIG. 7 is a cross-sectional view showing the image / sound output device 4A of the gaming machine according to
the present embodiment. The gaming machine of the present embodiment has the same configuration as that of
the above-described gaming machine 1 except that the gaming machine 1 of the present embodiment is provided
with a video and audio output device 4A instead of the video and audio output device 4. The image / sound
output device 4A is an audio output device according to the present invention, and includes an organic EL panel
5, an excitation device 6, a control unit 7 (not shown in FIG. 7) and a housing 8 as shown in FIG. In addition, the
lever member 6A is provided. Among these, the vibration exciter 6 is disposed on the side of the panel main body
51 constituting the organic EL panel 5 and at a position avoiding the Y driver 52 and the X driver 53. Then, the
displacement force generated by the excitation device 6 is transmitted to the panel main body 51 by the lever
member 6A rotatably supported by the housing 8. The lever member 6A and the vibration exciter 6 correspond
to the vibration exciter of the present invention in this embodiment.
[0042]
The lever member 6A has a substantially L-shape, and a substantially central portion thereof is rotatably
supported by the housing 8 by a support member (not shown). The contact portion 63 (FIG. 4) of the exciter 6 is

in contact with one of the end portions 6A1 and 6A2 of the lever member 6A. Further, the other end 6A2 is in
contact with the back surface of the panel main body 51. And the contact part 6A3 similar to the contact part 63
is provided in the side which opposes the panel main body 51 in the said edge part 6A2.
[0043]

The image / sound output device 4A is provided with the excitation device 6 on the side of the panel body 51,
and includes the lever member 6A for transmitting the displacement force of the excitation device 6 to the back
surface of the panel body 51. According to this, compared with the case where the vibration exciter 6 is disposed
on the back side of the panel main body 51, the dimension L (FIG. 7) in the depth direction of the housing 8 can
be reduced. Therefore, the thickness of the image / sound output device 4A can be reduced.
[0044]
〔3. Third Embodiment] Next, a third embodiment of the present invention will be described. The gaming
machine according to the present embodiment has the same configuration as the gaming machine according to
