PROBLEM TO BE SOLVED: To enable a sound image of a center location to be located in a center location as a function of a flat surface stereo type speaker. SOLUTION: A disintermediating diaphragm 4 having a left and right channel exciters 5L and 5R, and a center diaphragm 4C having a center channel exciter 5C are divided and arranged on the same flat surface. In the arrangement, the exciter 5C vibrates the center diaphragm 4C independent from the disintermediating diaphragm 4. Cushioning material frames 6 and 6C are arranged between a front surface external body 3 fixed to the body and the diaphragms 4 and 4C, and the vibrations of the exciters 5L, 5R, and 5C are transmitted to each of the diaphragms 4 and 4C so as to avoid mutual interference.
