Abstract

PURPOSE:To enhance the acoustic property of the speaker by detecting electrically the vibrations of the diaphragm through the detector and at the same time preventing assuredly the rotary vibration of the diaphragm. CONSTITUTION:Several points of diaphragm 11 are driven by several units of magnetic circuit 22, and coupler 29 is connected nearly vertically to diaphragm 11. Coupler 29 is supported by supporting device 31, and the vibration of coupler 29 caused by the vibration of diaphragm 11 is detected electrically by detector 43. At the same time, the rotary vibration of the diaphragm can be prevented assuredly. Thus the acoustic property can be enhanced for the speaker.
