Abstract

PURPOSE:To obtain a flat output sound pressure frequency characteristic, by attaching a magnetic circuit part to a frame so that a part of the circuit part has a vibration to the frame and varying the magnetic flux to a voice coil with a partial vibration of the magnetic circuit. CONSTITUTION:When a force is applied to a voice coil 13, a reaction force is applied to a magnetic circuit part in a direction opposite to the force applied to the coil 13. Furthermore a joint plate 20 supporting a magnet 16 plus plates 17 and 18 can have a vibration having a point of resonance at a low band having a high level of sound pressure. Thus a part of the magnetic circuit part has a vibration at a low band in the direction of an arrow ab so that the circuit part shifts in a direction opposite to the shift of a vibrating plate 10. As a result, the level of sound pressure is attenuated at a low band to obtain a flat characteristic.
