Patent ID: 6968071

Claim:
A speaker having a magnetic member installed on a diaphragm, comprising: a frame, forming a resonant space at the central position on one side of said frame, and having a diaphragm fixed on the periphery of said frame, and said diaphragm extending towards said resonant space; a central pillar, disposed at the bottom center of said resonant space of said frame; a winding, fixed on said central pillar; a magnetic member, having one end coupled to the central position of said diaphragm and a through hole disposed at the center of said magnetic member facing said resonant space, and the diameter of said through hole being slightly larger than the external diameter of said winding, wherein another end of said magnetic member passes through the through hole and is movably coupled to the winding, wherein said magnetic member comprises a corrugated damping film disposed at a position proximate said diaphragm, and said damping film extends alone a radial direction to couple with an appropriate position in said resonant space of said frame.
