Abstract
PURPOSE: To lower the lowest resonance frequency by constituting a vibration system of a damper, a cone edge and a coil spring.
CONSTITUTION: The support of a diaphragm is constituted of the damper 2 and the cone edge 1. Besides, by inserting the coil spring 3 which is made of metal and resin and has good restoration force around the circumference of the diaphragm 4, the exhaustion of the restoration force never occur, and in addition, the lowest resonance frequency can be lowered. Besides, an inherent resonance does not occur too much, and the distortion does not increase at the coil spring 3.
