Zusammenfassung:	An edge for a speaker making it possible to decrease a thickness of the speaker and achieve cost reduction by using no damper without lowering a sound quality is provided. The edge of a speaker is in a sheet-like and ring form and comprises an outer fixing part (11) formed on its outer peripheral part for fixing the edge to the frame (supporting member) (6), an inner fixing part (12) formed on its inner peripheral part for fixing the edge to the diaphragm (2), and a sheet-like part lying between the inner fixing part and the outer fixing part (connecting the inner fixing part and the outer fixing part). The respective convex portions are formed at least on both surfaces of the sheet-like part (13) at the boundary portion of the sheet-like part (13) and the outer fixing part (11), thereby forming the control parts (S1) and (S2) for controlling the vibration of the diaphragm (2).
