Document Type and Number:
WIPO Patent Application WO/2021/036127
Kind Code:
A1
Abstract:
Provided is a sound production apparatus, comprising a housing and a vibration assembly, with the vibration assembly comprising a diaphragm and a voice coil, the voice coil being of a hollow column structure, and the diaphragm being combined on one end face of the voice coil; and further comprising a system stabilizing member combined on an end face of the voice coil or combined on a side wall of the voice coil. The system stabilizing member is of a linear structure, is formed of a metal wire by means of winding, and comprises a first connection portion connected to the voice coil, a deformation portion, and a second connection portion connected to the housing. The present invention further provides an electronic device, comprising the above sound production apparatus. By using the sound production apparatus with such a structure, the voice coil will not be polarized under the conditions of large displacement, and the system stabilizing member with the new type of structure will not hinder the free vibration of the voice coil. The electronic device using the sound production apparatus has a good bass effect and a good acoustic performance.
