CONSTITUTION:At four corners of a carpet main body 1 speakers 11, 12, 13, and 14 are provided by burying them, and a controller 2 that consists of sound volume knobs 21, 22 on the right and left and amplification circuits 23, 24 on the right and left and a sound volume balancing volume knob 25 is connected to those speakers. And audio device 3 is connected to the input terminals 41, 42 on the right and left of the controller 2.

Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art In recent years, listening to music with audio equipment has become commonplace. Conventionally, a speaker connected to this kind of audio equipment 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, with such a conventional configuration of the audio equipment and the speaker, it is inevitable that the reproduced sound from the floor surface is required in order to effectively produce the sense of presence. It was impossible.

The present invention solves the above-mentioned conventional problems, and provides a carpet with which a more effective sense of realism can be obtained.

[0005]

In order to achieve the above object, the present invention has a speaker embedded in a carpet main body and is provided with an input terminal for a signal to the speaker connected to an audio device.

[0006]

[Operation] With the above structure, the carpet body is laid on the floor,
Since the reproduced sound can be produced from the floor surface, a more effective sense of presence can be obtained.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 is a plan view of a carpet according to a first embodiment of the present invention. FIG. 2 is A- of FIG.
It is an enlarged view of an A'section. FIG. 3 is an electrical block diagram. 1, 2 and 3, 1 is a carpet body,
Speakers 11, 12, 13, and 14 are provided between a front cloth 15 and a backing 16 made of felt or the like. That is, the speakers 11 to 14 are arranged at the four corners of the carpet main body 1, respectively, and the backing 16 is provided with the recesses 16a, which are buried therein so that the front cloth 15 becomes flat. 2 is a controller for the left volume control 21, the right volume control 22,
It is composed of a left amplification circuit 23, a right amplification circuit 24, and a volume balance volume 25. Reference numeral 3 denotes an arbitrary audio device, the output of which is connected to the left input terminal 41 and the right input terminal 42 of the controller 2. The volume controls 21, 22 also function as input protection devices for the speakers 11-14.

In the above configuration, it is assumed that the sound source of the audio equipment 3 is a sound close to nature, such as a bug sound or a river murmuring. In such a case, by switching the output of the audio equipment 3 to the carpet side, the listener can hear the reproduced sound from the lower surface where he / she is located, and the sense of presence is more effective than the reproduced sound propagating in the space. Is.

(Embodiment 2) FIG. 4 is a plan view of an electric carpet according to a second embodiment of the present invention, and FIG. 5 is an enlarged view of the section AA 'in FIG. In FIGS. 4 and 5, reference numeral 5 is a heating wire, and 6 is a temperature detection wire. Also the controller 2 '
In addition to the left and right volume controls 21, 22, the left and right amplification circuits 23, 24, and the volume balance volume 25, a temperature control circuit and a temperature setting circuit for the electric carpet are incorporated. Other configurations and operations are the same as those in the first embodiment.

In the first and second embodiments, 4
Two speakers are connected in parallel and distributed to the left and right channels to enable stereo reproduction, but not limited to this. For example, four speakers are each made independent and the left and right signals are phase-processed. It is also possible to produce a surround effect.

Further, although the controller 2 is arranged outside the carpet body 1 in this embodiment, it may be incorporated into the carpet body 1.

[0013]

As is apparent from the above embodiments, according to the present invention, the following effects can be obtained by embedding the speaker in the carpet body and providing the input terminal for connecting to the audio equipment.

(1) For the listener, since the reproduced sound comes out from the lower part where he / she is located, the presence of so-called natural sounds such as a bug's voice and the babbling of the river is more than that obtained from the space. More effective and peace of mind.

(2) When the audio device 3 is a television,
For example, at midnight, when you need to turn down the TV volume,
It is possible to switch the audio output and listen with the speaker closest to the carpet on which you are sitting, so you do not disturb the surroundings.

(3) Since the speaker is embedded in the carpet body that is routinely laid on the floor, it does not take up much space.

(4) Since the speaker is embedded in the carpet body, the same effect can be obtained without installing the speaker on the floor.

(5) If the carpet of the present invention is moved, it can be installed and used in a desired room.
