Abstract
A body-felt sound unit having a vibration transmitting member imbedded in a human body support member, for example, a chair, a bed, etc., and an electro-mechanical vibration transducer attached to the vibration transmitting member, the transducer generating mechanical vibration on receipt of a low-frequency current, thereby transmitting the vibration to the human body. The vibration transmitting member comprises a flat plate- or net-shaped member of a relatively large area, and the electro-mechanical vibration transducer is attached to the vibration transmitting member such that the direction of vibration generated from the transducer coincides with the direction of the width of the vibration transmitting member so as to transmit transverse vibration to the vibration transmitting member. Even if the vibration transmitting member is thin, the apparent rigidity becomes high, so that the transmission of vibration is made effectively.
