Abstract: Disclosed are a diaphragm for a sound generating device and a sound generating device. The diaphragm comprising at least one elastomer layer, wherein the elastomer layer is made of an ethylene propylene diene monomer; and the ethylene propylene diene monomer is formed by polymerizing three monomers, the three monomers being an ethylene monomer, a propylene monomer and a non-conjugated diene monomer respectively, a mass ratio of the ethylene monomer to the propylene monomer ranging from 0.25 to 4, and content of the non-conjugated diene monomer being 1%-15% of total content of the ethylene monomer and the propylene monomer. The ethylene propylene diene monomer has excellent high-temperature resistance and thermo-oxidative aging resistance; and after the rubber is made into the diaphragm, the diaphragm is capable of working in a high-temperature environment for a long time, maintaining not only excellent elasticity but also excellent anti-fatigue characteristic, thereby possessing excellent reliability.

Abstract: An acoustic device comprises a sound generating unit comprising a diaphragm. An acoustic wave at a front side radiates outwards through a sound outlet. A closed cavity is formed at a rear side of the vibrating diaphragm. Volume adjustment regions are provided in the closed cavity, the volume adjustment regions are a sound absorption portion, a porous sound absorbing material is provided on the sound absorption portion, and the volume adjustment regions are a flexibly deformable portion. The closed cavity is divided into first and second closed cavities by a partition. The first closed cavity is adjacent to the diaphragm, the second closed cavity is far away from the vibrating diaphragm. The flexibly deformable portion is at least part of the partition, and deforms flexibly. The sound absorbing material is provided in the first and/or the second closed cavity, and effectively increase the equivalent volume of the closed cavity.
