Bone vibration sound seat

Technical field

The present invention relates in the backrest of automotive sheet, keep the sound seat structure of loud speaker, particularly make it give the bone vibration sound seat of brain as the transmission sound of low range by the conduct vibrations that will produce with loud speaker from bass to the person's of taking a seat bone.

Background technology

For example, the vibrational system of loud speaker or vibration-variable frequency device etc. is built in seat etc., its vibration is conducted to brain as the bone of sound via human body.So-called osteoacusis system is arranged as everyone knows.And, the body propagated sensation that is produced by this osteoacusis system is led (vibro-acoustic) in a trance sense, euphoria, telepresenc and to give vent to aspect such as sense outstanding, but also effect with emotionality, instinct, so not only aspect music appreciation, also can used such as aspects such as loosening rest, music treatment.

In addition, the general employed seat bedding and padding of buffer body as seat, usually by foaming body moulding such as urethane foams, yet, because this kind foaming body lacks gas permeability, causes the transitivity of sound poor, and, because of the absorption of vibrations that its elasticity is brought, make its transfer of vibration also undesirable.

Thereby, as disclosed in the TOHKEMY 2005-223630 communique, in the seat of built-in bone drive system, for by make hollow continuous lines by the thermoplastic resin moulding as random ring or roll up the spring structure resinite that contacting the set that interweaves three-dimensionally and forming, be so-called netted buffer body, with its instead the buffer body of above-mentioned foaming body used.

Disclosed netted buffer body (spring structure resinite) is the three-dimensional structure with space of prescribed volume density in this communique, so compare with foaming bodies such as urethane foams, it is the duromer that has air permeability and good and be difficult for absorbing vibration, thereby, have sound, the desirable advantage of transfer of vibration.But, the netted buffer body of this kind is at sound, the outstanding reverse side of transfer of vibration, and its flexibility is relatively poor, thus as this communique openly, in the time of on constituting the whole face of taking a seat that netted buffer body is arranged on seat etc., the comfortableness when causing taking a seat easily reduces.

And, because the price of this netted buffer body is higher, thus think from its cost aspect be difficult to widely used.

And as this known formation, bass all is located in the netted buffer body by interior with loud speaker, tweeter, and its integral body is capped by Decorative Cover etc., so, can not negate that low range, high range are all by the possibility of obturation in Decorative Cover.That is to say,, then can not avoid the transmission effect of sound poor, thereby cause that itself is undesirable as sound seat functional if should think this known formation.
