Disclosed are a diaphragm for a sound producing device, and a sound producing device. The diaphragm is obtained by adding a filler, a structure control agent, and a cross-linking agent into a base polymer and mixing same, and performing molding at 80°C to 200°C, wherein the base polymer comprises one or more phenyl siloxane-containing polymers, and the content of phenyl in each of the phenyl siloxane-containing polymers ranges from 0.5% to 75% by weight; the damping of the diaphragm is 0.1-0.6. The present invention can improve the damping of the diaphragm and reduce distortion of the sound producing device. |
