Audio-band electromechanical vibration converter characterized in that a yoke having a permanent magnet and a magnetic gap formed therein is displaceably housed by a damper in a casing to which a vibration plate is attached; a coil attached to the casing is placed in said magnetic gap; and the casing gives an output of a mechanical vibration synchronized with a low-band audio-signal.

Audio-band electromechanical vibration converter

A device for giving an audio signal to a coil associated with an audio-band electromechanical converter uses a mixer, a first-stage low-pass filter, a limited and a second-stage low pass filter to correct distortion of the wave form of a signal from the limiter.

Audio-band electro-mechanical vibration converter

Audio-band electromechanical vibration converter characterized in that a yoke having a magnetic pole and a magnetic gap formed therein is displaceably housed by a damper in a casing to which a vibration plate is attached; a coil attached to the casing is placed in said magnetic gap; and the casing gives an output of a mechanical vibration synchronized with a low-band audio-signal.

A sound frequency reproduction system and apparatus has a chair for a human. A transducer is vibrated by a sound signal of appropriate frequency. The vibrating shaft of the transducer is directly fitted to the framework of the chair. The sound signal is provided to an acoustic device, including a speaker, located near the chair.
