DESCRIPTION JPH0646500
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an
acoustic device for a sounding floor covering.
[0002]
[0002] Listening to music with audio equipment is routinely performed. Conventionally, speakers
connected to this type of audio equipment are generally stationary box-type stationary speakers,
speakers embedded in a wall, or speakers mounted on a ceiling, and there is no direct sound
from the rug. .
[0003]
In addition, it is performed to adjust the balance volume on the left and right and the fader
volume on the front and rear in a car stereo etc. to make the sound out of only one of the four
speakers.
[0004]
In a conventional acoustic device, for example, a speaker for surround sound in a television,
when placed on the floor, the speaker becomes an obstacle when placed on the floor, and it is
acoustically desirable when the speaker is installed out of the way. There was a problem that
often did not happen.

[0005]
In addition, when sound is output from multiple speakers, it may be annoying at the night or
when there is a student or a person who has suffered from health, which may be annoying to
others.
[0006]
In addition, it is performed to adjust the balance volume on the left and right and the fader
volume on the front and rear in car stereo etc, and the sound is output from only one of the four
speakers, but in this case only L channel signal or R It becomes only a channel signal.
If the stereo sound of a television is produced only from one of a plurality of speakers in a
conventional car stereo system, it becomes a sound of only one channel, which is a serious
problem.
[0007]
The present invention solves the above-mentioned conventional problems, and it is possible to
create an acoustically stable sound field because it does not get in the way wherever it is placed
and the position of the speaker can be fixed.
[0008]
Another object of the present invention is to provide an audio device that can be heard without
missing any of L channel signal and R channel signal with only one arbitrary speaker among a
plurality of speakers.
[0009]
SUMMARY OF THE INVENTION In order to achieve the above object, the present invention
provides a rug body, a plurality of speakers attached to the rug body, and a stereo signal from a
sound source to any one of the plurality of loudspeakers. It has control means for mixing and
outputting the L channel signal and the R channel signal.

According to the present invention, with the above-described arrangement, the position of the
speaker can be fixed without causing any obstacle wherever it is placed, and an acoustically
stable sound field can be created.
[0011]
In addition, it is possible to listen without missing any of the L channel signal and the R channel
signal with only one arbitrary speaker among the plurality.
[0012]
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A sound-emitting covering which is
an embodiment of the present invention will be described below with reference to FIGS.
[0013]
FIG. 2 is a system configuration diagram of an embodiment of the present invention.
FIG. 1 is an electrical block diagram of the same system.
[0014]
Among the speakers 4a, 4b, 4c, 4d provided with L channel signals 2-L, R channel signals 2-R of
stereo signals from a sound source 1 such as a television as shown in FIG. The control means 5
which mixes and outputs arbitrary one is connected.
[0015]
FIG. 1 shows the contents of the control means.
When the sound of the sound source 1 such as a television is heard in a normal state, the Lchannel signal 2-L and R-channel signal 2-R of stereo signals are not mixed because the mixing
switch 51 in the control means 5 is off.

The muting switches 53a, 53b, 53c, 53d for turning off the input signals of the amplifiers 54a,
54b, 54c, 54d to the speakers 4a, 4b, 4c, 4d are also off and amplified from the speakers 4a, 4b.
The amplified L channel signal is output from the speakers 4c and 4d.
The mixing switches 51 interlock with the muting switches 53a, 53b, 53c and 53d, and when
three of the muting switches 53a, 53b, 53c and 53d are turned on, the mixing switch 51 is
turned on.
The resistors 52a, 52b, 52c and 52d are for preventing mutual interference when the muting
switches 53a, 53b, 53c and 53d are turned on and off.
[0016]
Next, when only one speaker 4d is output when the television 1 is viewed by sleeping alone, the
muting switches 53a, 53b and 53c are turned on, and the mixing switch 51 interlocked with this
is turned on. A mixed signal of channels is output.
[0017]
Similarly, mixed signals of L and R channels can be output from only one of the other speakers
4a, 4b, 4c.
[0018]
It goes without saying that the rug may be a carpet such as an electric carpet, a carpet, an
electric blanket, a blanket, an electric cushion, a cushion, a bed or a mattress.
Further, the speaker may be a paper speaker or the like.
[0019]
In addition, the fixing of the speaker can be embedded in the heat insulating material for a
cushion, bed or the like having a thickness.

As described above, according to the embodiment of the present invention, stereo signals from a
plurality of speakers attached to a rug body and a sound source can be used as an L channel
signal and an R channel signal to any one of a plurality of speakers. Since a plurality of speakers
having control means for mixing and outputting are arranged, they are not obstructed wherever
they are placed, and since the positions of the speakers can be fixed, an acoustically stable sound
field can be created.
[0021]
In addition, it is possible to hear without disturbing other people since the distance between the
person to be enjoyed and the speaker is close without missing both the L channel signal and the
R channel signal with only one arbitrary speaker among the plurality.
