ABSTRACT:
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.
