Abstract
PURPOSE:To simplify structure and manufacture and also to improve acoustic characteristics remarkably by removing rotational vibrations of a plane type diaphragm by a bobbin counted with it perpendicularly and a damper supporting the other terminal of this bobbin. CONSTITUTION:A vibration system consists of plane-shaped diaphragm 11, voice coil bobbin 13 bonded on the back surface of diaphragm 11, voice coil 14, and damper 15 coupled on the external circumference of bobbin 13. On the other hand, a drive system is composed of magnetic circuit 22. For example, bobbin 30 is bonded perpendicularly making center position P1 of diaphragm 1, i.e. the axis center of diaphragm 11 agree mutually, and free terminal part 29a of it is supported by damper 32. Consequently, rotational vibrations in arrow (a) and (b) directions of diaphragm 11 are converted into horizontal displacement vibrations in the arrow (c) direction of bobbin 30, which are damped effectively by the center coercive force of damper 32, so that rotational vibrations of diaphragm 11 can definitely be prevented.
