SOUND PRODUCTION DEVICE AND ASSEMBLING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/036128
Kind Code:
A1
Abstract:
The present invention provides a sound production device, comprising a housing and a vibration assembly. The vibration assembly comprises a vibration diaphragm and a voice coil combined to one side of the vibration diaphragm. The sound production device further comprises a system stabilization component; the system stabilization component is connected to the voice coil; the system stabilization component is a linear structure and 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 means of the sound production device having this structure, the voice coil is not polarized under the condition of large displacement, and the system stabilization component having a novel structure does not block the free vibration of the voice coil, either.
