Sound production device and assembling method therefor
Abstract:
Disclosed is a sound production device including a housing and a vibration assembly, the vibration assembly comprising a vibration diaphragm and a voice coil combined to one side of the vibration diaphragm; wherein the sound production device further comprises a system stabilization component connected with the voice coil; the system stabilization component is of a line-like structure formed by winding a metal wire, and comprises a first connection part connected to the voice coil, a deformation part, and a second connection part connected to the housing. By adopting the sound production device of this structure, the voice coil will not be polarized under the condition of large displacement, and the system stabilization component having a novel structure does not hinder the free vibration of the voice coil either.
