Abstract
Provided is a vibration diaphragm, comprising a wireless transmission unit which is arranged on one side of the vibration diaphragm where a voice coil can be fixed, and is used for electrically connecting with the voice coil, wirelessly receiving an audio signal transmitted from an external terminal and processing the audio signal to obtain audio current, and inputting the audio current into the voice coil; and a wireless charging unit which is electrically connected with the wireless transmission unit, generating electric energy under an action of an external power supply module and inputting the electric energy into the wireless transmission unit. Also provided are a vibration assembly, a sound generator and a sound generator module. With integration of the receiving and processing of audio signal on the vibration diaphragm, long-distance routing of a voice coil lead of the voice coil is avoided, noise is reduced, and product quality is improved.
