摘要
Disclosed are a vibrating diaphragm for a sound generating device, a method for preparing the vibrating diaphragm, and a sound generating device. The vibrating diaphragm comprises at least one modified thermoplastic polyester elastomer layer, wherein a modifier is involved which is at least one of a temperature: resistant resin, an inorganic filler and an anti-aging agent, and the modifier is added to a themoplastic polyester elastomer material. In an embodiment of the present invention, by adding the modifier to the themoplastic polyester elastomer material and sufficiently mixing the modifier when making a film layer, the aim of improving the temperature resistance of a moulded vibrating diaphragm is achieved.
