Abstract

PURPOSE:To linearize the relation of a sound output waveform against an electric input, that is, a sound input, and to suppress the distortion of a sound output by equalizing a displacements of a diaphragm to move forward and backward. CONSTITUTION:In a speaker provided with the diaphragm 1, whose vibrating surface is formed into a curve, and a driving end part 6, which is formed at the end of one side, at least, and drives the diaphragm 1 in a rectangular direction against its vibrating direction, and a diaphragm driving device 4, which is arranged so as to drive the driving end part 6 in a position lying nearly along the direction of the diaphragm 1, a cylindrical bobbin 21, which has a pole part 20, consisting of a magnet with bipolarity, and at the same time, a voice coil 13, wound around the outer circumference of said pole part 20 with interval between, is provided so as to be vibratable. Thus, the vibrating surface 1, formed into the curve, is vibrated and a sound is generated, and the displacements of the diaphragm 1 to move forward and backward can be equalized, and the relation of the sound output waveform against the electric input of the sound input is linearized, and the distortion of the sound output can be suppressed.
