ABSTRACT:
A body-sensible acoustic device and an electromechanical vibration converter for use in the same. The body-sensible acoustic device includes frames forming the structure of a chair having a seat and a back, canvas members spread on the frame, and driver units driven by low-frequency audio signals for transmitting vibration to the canvas members. The canvas members are formed of a net of fibers covered with a foamed synthetic resin. The vibration converter includes a drive coil disposed in the air gap of a magnetic circuit, a coil bobbin transmitting motion of the drive coil to the outer case of the converter, and a damper supporting the magnetic circuit on the outer case. A guide hole is formed in the magnetic circuit at its center and extending in the direction of the acoustic axis. A coupling member is fitted in the guide hole having end portions coupled to the outer case.
