PROBLEM TO BE SOLVED: To improve edge resonance without accompanying the lowering of efficiency or a rolling phenomenon in a speaker used for various kinds of acoustic equipment. SOLUTION: In the speaker, a sticking part 6d of an edge 6c on the side of an inner diameter of an edge roll is bonded and fixed to a folding part 13 on the outer periphery of a diaphragm 5c to bond and fix the diaphragm 5c onto a frame 10 via the edge 6c, and a strength of the diaphragm is reinforced by the folding part 13 to improve the edge resonance.
