PROBLEM TO BE SOLVED: To improve distortion of sound and deterioration in sound quality due to nonlinearity of a relation between an input level of a sound signal and an amplitude of a diaphragm resulting from a damper. SOLUTION: A voice coil 10 wound on a voice coil bobbin 9 mounted on an inner circumferential part of a diaphragm 6 is inserted to a magnetic air gap, a sound signal is supplied to the voice coil 10 to drive the diaphragm 6 in this speaker. Two curved shape dampers 11a, 11b are fitted between the voice coil bobbin 9 and a prescribed fixing part in opposite directions to each other.
