Abstract:
A diaphragm for electro-acoustic transducers, especially a diaphragm for speakers, and a film for the diaphragm excellent in the formability and the durability in high-output operation are obtained. A diaphragm for electro-acoustic transducers formed of a film that contains a polybiphenyl ether sulfone resin (A) having a specific repetitive unit or contains it and a crystalline resin (B) such as polyaryl ketone resin; and a film for use for the diaphragm.
