▎ 摘　　要

NOVELTY - Diaphragm includes at least one layer of silicone rubber film. The silicone rubber film layer is based on polysiloxane containing vinyl in its side chain as a base polymer, filler, crosslinking agent and core-shell structure catalyst are added to the base polymer. The shell structure catalyst is obtained by mixing and vulcanizing. The core-shell structure catalyst includes an inner core and a shell wrapped outside the inner core, and the inner core is platinum catalyst, and the shell is made of thermoplastic material. USE - Diaphragm for a sounding device for electronic device (claimed). ADVANTAGE - The diaphragm can realize the low-temperature rapid curing of the silicone rubber, thus improving the production efficiency of the diaphragm and reducing the energy consumption. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a sound generating device, which comprises a vibration system and a magnetic circuit system matched with the vibration system. The vibration system includes a diaphragm and a voice coil combined on one side of the diaphragm. The voice coil is driven to vibrate to drive the diaphragm to produce sound.
