Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to the improvement of a speaker system, and more specifically to a speaker system that has an economical configuration and can make the listener feel the bass directly as vibration. .

Prior Art and Problems Conventionally, there has been a demand for a speaker system that allows the user to directly feel bass sounds as vibrations. 1st
The figure is a sectional view of a conventional device that satisfies these demands, in which 1 is a seat consisting of a seating portion 2 and a backrest 3, and 4 is a diaphragm. The diaphragm 4 is vibrated by a signal obtained by amplifying the output signal of an audio device such as a cassette deck (not shown), and this vibration is transmitted to the listener seated on the seat 1. , since the diaphragm 4 must be newly buried in the seating section 2, it has the disadvantage of being expensive, and the wiring must be wired between the diaphragm 4 and the audio device, making the wiring complicated. There were flaws.

Purpose of the invention The present invention is an attempt to improve the above-mentioned drawbacks, and its purpose is to provide an economical structure that allows bass sounds to be directly felt as vibrations.
Examples will be described in detail below.

Embodiment of the invention Figure 2 is a sectional view of an embodiment of the invention.
1 is a seat consisting of a seating portion 12 and a backrest portion 13; 14 is a speaker; 15 is a speaker box;
16 is a passive cone, 17 is a seat frame,
18 is a mounting bracket, and 19 is a screw.

A speaker box 15 is attached to a hollow part provided in the seating part 12 by screwing together a seat frame 17 and a mounting bracket 18 with screws 19, and the speaker 14 is arranged so that its front face faces the seating part 12. is attached to the speaker box 15. When an audio signal is supplied to the speaker 14 from an audio device (not shown), the vibrations of the speaker 14 are transmitted to the listener via the seat 12, and the back pressure of the speaker 14 causes the passive cone 16 to act as a diaphragm. vibrates,
The reproduced sound of the audio signal is heard by a listener.

In this way, in this embodiment, the speaker 14 is embedded in the hollow part of the seating part 12, and the vibrations of the speaker 14 are directly transmitted to the listener, which is different from the conventional method, which requires a new diaphragm. The configuration can be made economical compared to the device.

FIG. 3 is a sectional view of another embodiment of the present invention,
Reference numeral 21 indicates a seating portion of the seat, 22 a speaker box, 23 and 24 speakers, 25 to 27 diaphragms, and 28 and 29 Saran nets.

A speaker box 22 is embedded in a hollow portion provided in the seating portion 21, and speakers 28 and 29 are attached to the speaker box 22 with their front surfaces facing downward. Speaker 23,2
When an audio signal is supplied to speaker 4, speaker 2
The back pressure of the speakers 3 and 24 causes the diaphragms 25 to 27 to vibrate, and the vibrations are transmitted to the listener via the seat 21, and the listener hears the reproduced sound from the front of the speakers 28 and 29.

FIG. 4 is a sectional view of still another embodiment of the present invention, in which 31 is a seating portion, 32 is a speaker, 33 is a retaining plate for holding the speaker 32, 34 is a saran net, and 35 and 36 are provided on the retaining plate 33. This is a through-hole.

The inner wall surface 37 of the hollow part of the seating part 31 is airtightly treated and also serves as a diaphragm, and the hollow part is sealed by a retaining plate 33. In other words, the hollow portion forms a speaker box. The speaker 34 is attached to the holding plate 33 with its front surface facing downward. When an audio signal is supplied, the seat 31 vibrates due to the back pressure, and the vibration is transmitted to the listener and the speaker 34 The listener hears the sound played from the front. In addition, through holes 35 and 36
This is to prevent pressure from being applied to the speaker 34 when sitting on the seating portion 31.

Effects of the invention As explained above, the present invention has a speaker buried in the seating area of the seat, and there is no need to provide a diaphragm like in conventional devices, so it is possible to generate vibrations and reproduce them with an economical configuration. This has the advantage that the sound can be directly transmitted to the listener. Furthermore, if the present invention is applied to a car speaker system,
This has the advantage of eliminating the problem of where to install the speakers.

5 and 22 are speaker boxes, 16 is a passive cone, 17 is a seat frame, 18 is a mounting bracket, 19 is a screw, 28, 29, and 34 are Saran nets, 33 is a holding plate, and 35 and 36 are through holes.

Claims (1)

[Claims for Utility Model Registration] A hollow part provided in the seating part of a seat, a speaker buried in the hollow part, and a diaphragm driven by the back pressure of the speaker buried in the hollow part. The speaker system is characterized in that one of the speaker or the diaphragm is embedded in the hollow part so as to apply vibration to the seating part, and the other is embedded in the hollow part so as to radiate reproduced sound. speaker system.
