Abstract

PURPOSE:To raise the resonance near edge to outside of audibile range and form a speaker of a wide frequency range by making the thickness of the flat part connecting a dome form diaphragm and edge more than twice the thickness of the diaphragm and edge. CONSTITUTION:The thickness of the flat part 3 between a dome form diaphragm 1 and edge 2 is set twice the thickness of the diaphragm 1 and edge 2. In the results of calculations (sound pressure-frequency characteristics) by the finite elements of this case, A, B, C indicate the sound pressure characteristics of the edge 2, diaphragm 1 and the entire part thereof, respectively, and the resonance near the edge 2 is produced near 26K Hz, which has moved to the higher region than the neighborhood of 16K Hz of the case when the thickness of the flat part 3 is the same as that of the diaphragm 1 and edge 2. Making the thickness of the flat part 3 more than twice the thickness of the diaphragm and ege in this way enables the resonance near the edge to be raised to outside of the audible ragne and the speaker of a wide frequency range to be formed.
