Abstract
PURPOSE:To equalize displacement moving to the front and rear directions of a diaphragm and to suppress the distortion of a voice output by specifying the curvature of a vibrating surface. CONSTITUTION:A sandwiching angle theta, between a straight line to connect the top of the vibrating surface formed in the curvature of a diaphragm 1 and the driving point of the vibrating surface, and a horizontal surface passing the driving point, is set in the range of 22.5+ or -7.5 deg.. When the angle theta is small, a difference between front direction displacement and rear direction displacement is large, and a distortion is generated. When the angle is large, though a symmetry becomes good, the absolute value of the displacement is made small and an efficiency is bad. In such a way, by setting the curvature of the vibrating surface, the displacement moving to the front and rear directions of the diaphragm 1 can be made equal, the relation of a sound output waveform to an electric input which is a sound signal is made linear, and the distortion of the voice output can be suppressed.
