Abstract

PURPOSE:To secure a sufficient sound pressure without any unnatural sound quality, by attaching a magnetic circuit to a frame so that the magnetic circuit part can have a vibration to the frame. CONSTITUTION:When a force is applied to a voice coil 13, a reaction force in a direction opposite to the force applied to the voice coil 13 is applied to the magnetic circuit part. Furthermore an edge 19 supporting the magnetic circuit part can have a vibration having a point of resonance at a low band having a high level of sound pressure. As a result, the magnetic circuit part has a vibration in the direction of an arrow as so that it shifts in a direction opposite to the shift of a vibrating plate 10. Thus the level of sound pressure is attenuated at a low band to obtain a flat characteristic.
