EDGE FOR SPEAKER, AND FORMING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To maintain an edge shape being set while repeating elastic deformation by the large-amplitude vibration of a diaphragm, and to achieve ruggedness that endures the iterated vibration of large amplitude, and to obtain a high sound pressure in an edge for speakers provided at the end section of a diaphragm for speakers. SOLUTION: A base material 1B where hot forming of thermosetting resins such as phenol resin is performed with fabric materials such as cotton and aramid fiber is arranged in an edge forming member 1A made of the molding of a rubber-based member, thus improving the shape maintenance function of the edge 1 for speakers.
