Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rug having a speaker built therein.

[0002]

2. Description of the Related Art In recent years, listening to music with audio equipment has become commonplace. Conventionally, a speaker connected to an audio device of this type is generally an orthodox box-type stationary speaker, a speaker embedded in a wall, a speaker mounted on a ceiling, or the like.

[0003]

However, in the above-mentioned conventional configuration, there is a problem in that it is inevitable in the case where a reproduced sound from the floor is required for more effectively producing a realistic sensation. Had.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a rug having a speaker which is more effective, more safe, and has a good appearance. ..

[0005]

In order to achieve the above object, a rug incorporating a speaker of the present invention comprises a main body composed of a front cloth and a backing material, and an upper case and a lower case attached to the backing material of the main body. The speaker case, the speaker arranged in the speaker case, and the lead wire connected to the speaker are provided, and the lead wire is arranged between the front cloth and the backing material.

[0006]

According to the present invention, since the reproduced sound can be emitted from the floor surface in the above-mentioned structure, a more effective presence can be obtained.

Further, since the lead wires connected to the speaker arranged in the speaker case are wired in the rug body between the front cloth and the backing material, the lead wires can be directly stepped on or hooked. The stress applied to the lead wire is eliminated, the safety is improved in use, and the troublesome treatment of the lead wire is eliminated.

Further, since the lead wire connected to the speaker is made invisible from the outside, it looks good.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 2 and 3,
Speaker cases 2a, 2b, 2c, and 2d are provided at four corners of a rug body (hereinafter referred to as a body) 1, and speakers 3a, 3b, 3c, and 3d are disposed inside the speaker cases. A lead wire 4 is connected to the speakers 3 a, 3 b, 3 c, 3 d and is connected to the controller 5. Left volume control 6, right volume control 7, left amplification circuit 8, right amplification circuit 9 and volume balance volume 10.
And speaker 3 arranged at the four corners of the main body 1.
It is electrically connected to the lead wire 4 connected to a, 3b, 3c and 3d. The output from the arbitrary audio equipment 11 is the left input terminal 12 and the right input terminal 13 of the controller 5.
It is connected to the.

The left and right amplifier circuits 8 and 9 are the speaker 3
It also functions as an input protection device for a, 3b, 3c, and 3d.

Next, a specific structure of this embodiment will be described with reference to FIGS. 1 and 4 to 6. As shown in FIGS. 1 and 4 to 6, the main body 1 is composed of a front cloth 14 and a backing material 16 having an opening 15 made of felt or the like, and the front cloth 14 and the backing material 16 are integrated by an adhesive. Has been converted.

The speaker case 2 has an opening 15 in the backing 16.
The upper case 17 and the lower case 18 are provided. A plurality of through holes 19 are provided on the upper surface of the upper case 17, and the speaker 3 disposed inside the speaker case 2 has a plurality of sound output side edges of the speaker 3 provided on the upper surface of the upper case 17. It is fixed by being opposed to the individual through holes 19 and being joined to a plurality of system stoppers 20 provided on the inner surface of the upper case 17. The lead wire 4 connected to the speaker 3 arranged in the speaker case 2 is wired between the front cloth 14 and the backing material 16. That is, the lead wire 4 connected to the speaker 3 is wired in the main body 1. Further, the lead wires 4 connected to the speaker 3 are collected at one place of the main body 1, taken out from the main body 1, and electrically connected to the controller 5. Opening 15 provided in backing 16 by upper case 17 and lower case 18
The end edges of the whole circumference are sandwiched, and the plurality of mounting bosses 21 of the upper case 17 and the plurality of mounting bosses 22 of the lower case 18 which are provided at positions opposite to each other are tightened and fixed by mounting screws 23. Since the speaker case 2 is thin, the mounting screw 23 has a small engagement dimension, so that the mounting boss 21 of the upper case 17 has a metal insert nut 24 embedded therein.

The operation of the rug having the speaker constructed as described above will be described below. First, it is assumed that the sound source of the audio device 11 is a sound that is close to nature, such as a bug sound or a river murmuring. In such a case, by switching the output of the audio device 11 to the rug side, the reproduced sound can be heard from the lower surface where the listener is located, and the sense of presence is more effective than the reproduced sound propagating in the space. is there.

The lead wire 4 connected to the speaker 3 arranged in the speaker case 2 is attached to the front cloth 14 and the backing material 16.
It is wired between and. That is, since the lead wire 4 connected to the speaker 3 is wired inside the main body 1, the lead wire 4 is not directly stepped on or caught. Therefore, no stress is applied to the lead wire 4, the safety is higher in use, and the troublesome treatment of the lead wire 4 is not necessary.

Further, since the lead wire 4 connected to the speaker 3 is hidden from the outside, it looks good.

In this embodiment, four speakers are used as two speakers.
They are connected in parallel one by one and are distributed to the left and right channels to enable stereo playback, but this is not a limitation.
For example, it is possible to produce the surround effect by independently processing the four speakers and subjecting the left and right signals to phase processing.

Further, in the present embodiment, the general rug having the built-in speaker has been described, but the same effect can be obtained also in the rug having a heating wire or the like.

Further, although the controller 4 is arranged outside the rug body 1 in this embodiment, it may be incorporated in the rug body 1.

[0019]

As is apparent from the above embodiments, according to the present invention, the reproduced sound can be emitted from the lower surface on which the listener is located, so that a so-called natural sound such as a bug's voice or a river murmuring can be produced. The sense of realism is more effective and peace of mind than that obtained from space.

Further, since the speaker is mounted in the rug that is laid on the floor everyday, it does not take up much space.

Further, since the lead wire connected to the speaker arranged in the speaker case is wired in the rug body between the front cloth and the backing material, the lead wire can be directly stepped on or hooked. The stress applied to the lead wire is eliminated, the safety is improved in use, and the troublesome treatment of the lead wire is eliminated.

Further, since the lead wire connected to the speaker is not visible from the outside, it is possible to realize a rug with a built-in speaker, which has an excellent appearance.
