Abstract

The invention discloses an osteoconductive loudspeaker unit of a multi-resonance system. The loudspeaker unit comprises a support, a magnetic circuit system and a vibration system, wherein the magnetic circuit system is arranged on the support; the vibration system comprises a first vibration system and at least one second vibration system, the first vibration system comprises a first elastic sheet, a first washer and a first permanent magnet, the first elastic sheet is connected with the support, the washer is arranged on the first elastic sheet, and the first permanent magnet is arranged on the first washer; and the second vibration system comprises an elastomer and a fixing potion connected together, and the second vibration system is suspended outside a space encircled by the support and the first vibration system. The loudspeaker unit has the characteristic of good low frequency effect.

Description

technical field [0001] The invention relates to the technical field of electro-acoustic conversion, and more specifically, relates to a multi-resonance system bone conduction loudspeaker unit. Background technique [0002] The existing bone conduction loudspeaker includes a bracket, a PCB fixed on the bracket, a first permanent magnet, a coil, an iron core, a lower washer and a vibrator part. The vibrator includes upper washer, shrapnel and upper magnet. [0003] Existing bone conduction speakers have only one vibration system, so there is only one resonance peak at low frequencies, such as Figure 9 As shown by the curve a in the speaker, the frequency response range of the speaker is narrow, and the sound is thin, which affects the use effect. Contents of the invention [0004] An object of the present invention is to provide a new technical solution for a bone conduction loudspeaker unit. [0005] According to a first aspect of the present invention, a bone conduction...
