Title:
LOUDSPEAKER UNIT AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/125401
Kind Code:
A1
Abstract:
The present application provides a loudspeaker unit and an electronic device. The loudspeaker unit is provided with a limiting structure corresponding to a non-fixed part of a base of an armature for limiting the maximum offset of the non-fixed part. In the case that the loudspeaker unit is subjected to mechanical shock, the limiting structure effectively prevents the offset of the non-fixed part of the base of the armature from being too large, such that the fault caused by plastic deformation due to the overlarge offset of the non-fixed part of the base of the armature is basically avoided. The electronic equipment comprising the loudspeaker unit can be an earphone or a hearing aid, etc.
