Abstract

The invention discloses a bone conduction loudspeaker device, comprising a bottom shell, a damping block installed on the bottom shell, a voice coil support installed on the damping block, a voice coil installed on the voice coil support, a vibration system installed on the damping block and the voice coil support, a magnetic system installed on the vibration system, a flexible piece installed on the vibration system, and an upper cover engaged with the bottom shell. The vibration system comprises a fixed support, an acoustic vibration sheet installed on the fixed support, an acoustic vibration transmission sheet installed on the outer edge of the acoustic vibration sheet, and an acoustic vibration transmission plate installed in the middle of the acoustic vibration sheet. The magnetic system comprises a slab, an inner ring magnet installed on the slab, an inner magnetic conduction plate installed on the inner ring magnet, an outer ring magnet installed on the slab, an outer magnetic conduction plate installed on the outer ring magnet, and a T-shaped column. The T-shaped column sequentially penetrates through the inner magnetic conduction plate, the inner ring magnet and the slab, so as to connect and fix the inner magnetic conduction plate, the inner ring magnet and the slab. The voice coil is arranged in a gap formed between the inner ring magnet and the outer ring magnet.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a bone conduction loudspeaker device. Background technique [0002] In the existing market, bone conduction technology is mostly used in the military market. At the same time, with the continuous in-depth research on technology, it is gradually entering people's daily life. Because its sound transmission is realized by means of vibration and sound transmission, it has strong anti-interference ability and does not need to receive sound through the external auditory canal for transmission. In daily life, it can receive external information while liberating both ears. Existing bone conduction speakers (bone conduction vibrators with moving iron structures in the military field) cannot have the same frequency response curve as traditional speakers due to the constraints of their structure and material properties, which makes it difficult for them to have a place in the civilian ...
