Title:
BONE CONDUCTION VIBRATION SOUND-PRODUCING UNIT AND BONE CONDUCTION EARPHONE
Document Type and Number:
WIPO Patent Application WO/2024/083140
Kind Code:
A1
Abstract:
A bone conduction vibration sound-producing unit and a bone conduction earphone. The bone conduction vibration sound-producing unit comprises an outer support (2), an elastic sheet (3), a magnetic circuit assembly (4) and a voice coil assembly (5). The outer support (2) comprises an accommodating hole (20), and the accommodating hole (20) is open from a first end (2a) and a second end (2b) of the outer support (2); the elastic sheet (3) comprises an outer ring (30) connected to the first end (2a) of the outer support (2) and a middle plate (31) located in the outer ring (30) and elastically connected to the outer ring (30); the magnetic circuit assembly (4) is located in the accommodating hole (20) and is connected to the middle plate (31); and the voice coil assembly (5) is connected to the second end (2b) of the outer support (2), and the magnetic circuit assembly (4) and the voice coil assembly (5) are oppositely arranged spaced apart from each other. The precision of spacing between the magnetic circuit assembly (4) and the voice coil assembly (5) is ensured more easily, thereby facilitating improving the yield of the complete bone conduction earphone.
