Abstract: A diaphragm applied to a sound producing device, a sound producing device, and a method for assembling the same. The diaphragm comprises a film layer prepared by means of a crosslinking reaction of at least one of an ethylene-acrylate copolymer and an ethylene-acrylate-carboxylic acid copolymer. The molecular structure of the diaphragm comprises a vinyl-acrylic group. The group causes the material to have a less symmetrical chemical structure, a reduced tacticity and an increased steric hindrance, such that the diaphragm has a high loss factor, and the sound producing device achieves a good damping effect.
