NOVELTY - Vibrating iaphragm, obtained by adding fillers, structure control agents, and crosslinking agents into the base polymer, kneading, and heating and molding at 80-200degrees Celsius, where the base polymer includes phenyl-containing siloxane polymers, and the content of phenyl groups in each of the phenyl-containing siloxane polymers is 0.5-75 wt.% and the damping of the diaphragm is 0.1-0.6, is claimed. USE - Vibrating diaphragm used for sound-producing device (claimed). ADVANTAGE - The vibrating diaphragm improves the damping of the vibrating device and reduces the distortion of the sounding device, thus improving the listening difference and user experience of the sound-producing device, and hence improving the sound quality of the device.
