VIBRATING DIAPHRAGM FOR MINIATURE SOUND PRODUCTION DEVICE, AND MINIATURE SOUND PRODUCTION DEVICE

摘要

Disclosed are a vibrating diaphragm for a miniature sound production device, and a miniature sound production device. The vibrating diaphragm for a miniature sound production device is made of a polyacrylate copolymer, wherein the polyacrylate copolymer comprises "an ethylene-acrylate copolymer", the polyacrylate copolymer has a mass ratio of a polyethylene block to a polyacrylate block of 0.05-10, and the polyacreylate copolymer is mixed with a cross-linking agent, the cross-linking agent comprising a peroxide cross-linking agent and a co-crosslinking agent. The vibrating diaphragm provided by the present invention has better acoustic properties.
