DIAPHRAGM FOR MINIATURE SOUND GENERATION DEVICE AND MINIATURE SOUND GENERATION DEVICE

Abstract: the present disclosure relates to the technology field of acoustic product. disclosed are a diaphragm for miniature sound generation device and a miniature sound generation device. the diaphragm includes a rubber film layer formed by cross-linking reaction of an acrylate polymer, wherein the acrylate polymer contains carboxylic acid group, the cross-linking agent is an amine cross-linking agent. the present disclosure effectively improves the degree of cross-linking by using the acrylate polymer containing carboxylic acid group and the amine cross-linking agent, resulting in excellent resilience and temperature resistance of the diaphragm; at the same time, it allows the diaphragm forming method to be unrestricted and reduces preparation cost; it also improves the low-frequency performance of the miniature sound generation device, such that it has a full bass and a comfortable listening experience.
