By using the horizontal rack 35 and the vertical rack 36 in combination in this manner, the frame
37 can be driven in a stable state with less rattling.
[0027]
The display panel portion 31 is horizontally moved from the lower position of the top plate 1
shown in FIG. 1A by the above drive mechanism and moved to a position protruding from the
edge of the top plate 1 and then turned. It can be moved to a position raised from the top 1 as
shown in FIGS.
The rising angle of the display panel unit 31 can be set arbitrarily by counting pulses of the
rotation angle obtained from the motor.
[0028]
Although the screen of the display panel section 31 can be viewed even under the tabletop 1, it
can be seen from a wide range at a position raised from the tabletop 1, and the screen can be
touched with a finger. Since it can do, it becomes possible to operate the touch panel provided in
the display panel section 31.
A key for driving the display panel unit 31 is provided on the panel of the amplifier built-in DVD
player 25 shown in FIG. 1B.
[0029]
When sitting in front of the table of the above configuration, the position of the ear falls within
the service area of the middle to high-reproduction speaker units 15 to 18. Therefore, it is
possible to listen to middle to high-pitched sound within a range that causes no problem in
frequency characteristics. it can.
[0030]
Furthermore, since the speaker units 15 to 18 for middle to high-pitched sound reproduction
10-05-2019

used here are of the elongated track type, the width of the diaphragm is small in the vertical
direction and the directivity becomes wide, so even sitting up and listening There is no big
difference in sound quality even if you listen.
[0031]
In addition, the width of the diaphragm becomes longer in the horizontal direction, so the
directivity becomes narrower. However, since the speakers are on both sides of the table, when
listening on the side without the speakers, the speakers on both sides The sound is synthesized,
and when it is heard on the side with the speakers, a loud sound field is formed without a large
difference in volume because only the sound from one of the speakers is heard.
[0032]
The speaker unit for bass reproduction is horizontally disposed under the table top 1, and the
sound outputted to the upper side of the diaphragm and the sound outputted to the lower side
are shifted by half wavelength at the center frequency of the desired bass. Both sounds are not
canceled because they are synthesized and output from the port 12 provided on the table bottom
plate.
That is, the upper and lower sounds of the diaphragm are effectively used.
[0033]
Furthermore, since the synthesized sound comes out through the port 12, the sound can be taken
out without loss by adjusting the resonance frequency of the port 12 and the cavity to the abovementioned desired frequency.
On the other hand, sound with a wavelength four times the sound path length can be efficiently
extracted by resonance.
At the same time, sounds of adjacent frequencies before and after that are also output
concomitantly, so that even a narrow cavity can effectively reproduce bass.
10-05-2019

[0034]
The directivity in the low band is wide, so it can be heard from anywhere around the table
without any problem in the frequency characteristics.
In the present embodiment, the port 12 is provided on the table bottom plate so that uniform
bass can be obtained from anywhere around the table.
[0035]
Each speaker and the display device 30 are connected to the amplifier built-in DVD player 25. By
attaching the DVD to the DVD player and reproducing it, it is possible to watch a movie or the
like. The display device 30 can be viewed as stored or taken out.
[0036]
Further, communication with a person in a store can be performed using the optical microphone
21. Furthermore, the optical microphone 21 can be used as a microphone for hands-free
communication of a portable telephone.
[0037]
The optical microphone is for reflecting the laser light from the light emitting portion by the
diaphragm and receiving it by the light receiving element to convert the position signal of the
diaphragm into an electric signal, and since it has strong directivity in the front direction, It is
difficult to pick up voices and noises other than the voice from the person sitting in front of the
microphone, and a clear conversation can be realized.
[0038]
It is also possible to configure this table to communicate information with the management room
of the store by wire or wirelessly, and use the display device as a touch panel to order meals and
the like.

Although the embodiment is configured as described above, the invention is not limited thereto.
For example, a CD player or a television tuner may be incorporated instead of a DVD player, and
a CD player or a television together with the DVD player. A John Tuner may be incorporated.
It is also possible to incorporate a receiver using a communication scheme such as Bluetooth.
[0040]
According to the table provided with the display device of the present invention, the display
device can be viewed both when it is under the top plate and when it is located above the top
plate. It is possible to view images, movies, sports, and various image information accompanying
music while eating under the condition that the display device is stored under the top plate.
[0041]
When necessary, the display device can be brought up to the outside with one touch and used as
a touch panel to perform operations such as a meal order.
In addition, many people around the table can easily view the screen when the display device is
activated.
[0042]
Further, by incorporating a speaker in the table, it is possible to flow information using voice, and
further, by incorporating a microphone, it becomes possible to exchange voice in a store.
And, by using an optical microphone as a main microphone, directivity in the front direction
becomes strong, it is difficult to pick up surrounding noise, and clear communication becomes
possible.
