Document Type and Number:
WIPO Patent Application WO/2020/258142
Kind Code:
A1
Abstract:
A sound producing device (10), comprising a sound producing monomer (1) and an FPC board (4) electrically connected to the sound producing monomer (1). The sound producing monomer (1) comprises a frame (11) and a magnetic bowl (12) provided on the frame (11). The FPC board (4) is electrically connected to the magnetic bowl (12) by means of a conductive plate (2) to realize grounding, and the conductive plate (2) is welded and fixed with the magnetic bowl (12). The FPC board (4) is electrically connected to the magnetic bowl (12) by means of the conductive plate (2) to realize grounding, and the conductive plate (2) is welded and fixed with the magnetic bowl (12), so that reliable conduction between the FPC board (4) and the magnetic bowl (12) is realized, static electricity generated by the sound producing device (10) can be smoothly eliminated by means of the grounding of the FPC board (4), and the performance of the sound producing device (10) is effectively ensured.
