An audio frequency electromechanical vibrator comprising a flat plate permanent magnet magnetized in a predetermined direction and a coil wound around the permanent magnet for crossing the direction of magnetization. The permanent magnet and coil are fixedly disposed in a yoke which is elastically supported in a case through a spring plate. The case partly consists of a magnetic plate which is placed for opposing the permanent magnet to form a magnetic flux circuit, whereby the vibrator can generate a vibration corresponding to an audio signal applied to the coil. |
