Description

[Detailed Description of the Invention] The present invention relates to a sensory acoustic sheet equipped with a vibrating body driven by a low-frequency audio signal and a vibrating unit made up of a vibrating body.

In recent years, when enjoying music with audio equipment, etc.
By extracting only the bass range of a music signal and transmitting this music signal to a vibration device attached to a seat or the like, it is possible to vibrate the vibration device and reproduce music with a sense of realism.

Here, a conventional sensory acoustic sheet will be explained with reference to FIG.

FIG. 1 shows a vibrating unit 7 consisting of a vibrating body 5 and a diaphragm 6 held between a spring 3 stretched between a cushion material 4 and a frame 2. As shown in FIG.

In the sensory acoustic sheet 1 having the above structure, the vibrations generated by the vibrator 5 are transmitted to the diaphragm 6, causing the entire vibration unit 7 to vibrate. After this, the vibration unit 7 vibrates the spring 3 and the cushion material 4 at the same time, but since the structure is such that a thick plate-like rigid diaphragm is sandwiched between the cushion material and the spring, the comfortable seating that the seat originally has. It ended up cutting my feelings in half.

The purpose of the present invention is to eliminate the above-mentioned drawbacks and to provide a sensory acoustic sheet having a simple structure.

That is, the present invention consists of an outer member such as a spring and cushion material stretched between bone frames, a vibrating body driven by a low-frequency audio signal, and a vibrating body that holds the vibrating body and vibrates over a wide range. In a sensory acoustic sheet equipped with a vibration unit consisting of a diaphragm for the purpose of achieving the above object, both sides of the diaphragm are bent into an L-shaped cross section, and both ends are fixed to the spring by welding. It is something to be achieved.

Hereinafter, the present invention will be explained with reference to the drawings showing embodiments.

FIG. 2 is a rear perspective view for explaining the internal structure of the sensory acoustic sheet of the present invention, in which the external shape of the sensory acoustic sheet 10 is formed by a bone frame 11,
A cushion material 12 is provided on the seated person's side so as to include the bone frame 11, and a spring 13 is stretched between the bone frames 11 in the left-right direction. A vibration unit 16 consisting of a vibrating body 14 and a diaphragm 15 is fixed to the back side of the spring 13 by welding.

In addition, FIG. 3 shows the vibration unit 16 shown in FIG.
It is a diagram showing a cross section taken along the line A-A of
Both ends of 6 are bent into an L-shaped cross section to form a joint 161. The diaphragm 15 is fixed to the spring 13 only at the joint 161, and is disposed with a gap of width m from the end of the joint 161 so that the vibrating body 14 does not come into direct contact with the spring 13.

In the sensory acoustic sheet having the above structure, vibrations generated by the vibrating body 14 are transmitted to the diaphragm 15,
The entire vibration unit 16 is vibrated, and the vibration is further transmitted to the spring 13 through the joint 161 of the vibration unit 16, and then the entire seat is vibrated.

As described above, in the sensory acoustic seat according to the present invention, since the diaphragm is arranged on the back side of the spring with a certain gap, it is possible to obtain the good seating feeling inherent in the seat.

In addition, the vibration unit has joints formed at both ends, and the diaphragm 15 and the spring are joined only by the spring and the joint so that they do not come into direct contact with each other, thereby preventing the generation of unpleasant noises that conventionally occur. can.

Furthermore, since the vibrations generated by the diaphragm are transmitted to the seated occupant through the spring, the vibrations do not occur locally, but instead cause the entire seat to vibrate, making it possible to listen to music with even more immersion.
