Abstract

PURPOSE:To make the characteristic of the speaker wide-band and flat, by providing the first flat-plate diaphragm of a ring form and by providing the second flat-plate diaphragm in the aperture part of the center of the first plane-plate diaphragm. CONSTITUTION:In a low frequency, diaphragms 13 and 15 reciprocate in the same manner and operate similarly to the speaker having one large diaphragm. Diaphragm 15 reciprocates up to the resonance frequency of itself; and in a frequency higher than this frequency, diaphragm 15 is attenuated, and only diaphragm 13 is driven. Since the diameter of diaphragm 13 is smaller than that of diaphragm 15, diaphragm 13 has a high resonance frequency and reciprocated up to a very high frequency.
