この発明は体感音響装置に関し、さらに詳しくは、ヘッ
ドレストを備え、これに左右チャンネル再生用スピーカ
を取り付けて構成した体感音響装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sensory acoustic device, and more particularly to a sensory acoustic device comprising a headrest and left and right channel reproduction speakers attached thereto.
従来よく知られている体感音響装置はソファタイプの着

置の低域再生出力の一部でトランスデュサを駆動し、聴
覚では再生音を聴きながら、体では低域再生出力による
振動を感じるように構成したものである。A well-known sensory acoustic system incorporates a transducer into a sofa-type seated person, and drives the transducer with a portion of the low-frequency playback output of the stereo system. It is constructed so that you can feel the vibrations caused by the reproduced output.

．３はヘッドレストの両傍に配置されており、体感者の
左右両耳の近くに再生音の音像が存在するのである。For example, as shown in Figure 5, a transducer l is built into the backrest, extracts the low frequency components of both the left and right channels, amplifies and drives this output, and furthermore, The system is configured so that the reproduced sound can be heard through speakers 2.3. In this case speaker 2
．． 3 are placed on both sides of the headrest, and the sound image of the reproduced sound is present near the listener's left and right ears.

分により振動が得られることから、体に感じる低域音と
、聴覚上の低域成分とがアンバランスとなり、感覚的に
違和感をぬぐい去ることができ、ない問題があった。In the above-mentioned sensory sound system, since the speakers are located on both sides of the headrest, it is not possible to increase the volume, and there is a limit to the low frequency reproduction ability, and low frequency codification tends to be insufficient for the auditory sense. In addition, since vibrations can be obtained with enough low-frequency components to feel, the low-frequency sounds felt by the body and the low-frequency components perceived by the auditory sense become unbalanced, and it is possible to eliminate the sense of discomfort. There were no problems.
そこで、この発明は聴覚上の低域音と、体感上の低域音
とが完全に、同調できる体感音響装置を提供することを
目的とするものである。SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a sensory acoustic device that can completely synchronize the auditory low-frequency sound and the bodily low-frequency sound.

に構成したことを特徴とするものである。In order to solve the above-mentioned problems, the present invention provides a sensory sound device that includes at least a backrest and a headrest. The device is characterized in that it is configured to be equipped with a speaker for the low frequency range, and is also characterized in that it is configured to reproduce the low frequency range using independent speakers for both the left and right channels. This system is characterized by being configured so that it can be played back using a single speaker.
上述のような体感音響装置は不足がちな低域成分だけを
ヘッドレスト内部に収容した独立したスピーカで再生す
るから聴覚上と、体感上との低域再生音が一致する。Since the above-mentioned sensory sound device reproduces only the low frequency component, which tends to be insufficient, through an independent speaker housed inside the headrest, the low frequency reproduced sound that is heard and experienced matches.

Speaker units 14L and 14R for low frequency reproduction are attached to this baffle plate corresponding to the left and right channels. Furthermore, the headrest 13 is wrapped in a shoe sheen to provide a good feel to the occupant, and is designed not to interfere with low frequency reproduction.
