Problems solved by technology

[0004] However, in the sound-generating device in the related art, the diaphragm and the elastic support assembly are respectively fixed on the opposite ends of the voice coil, although the elastic support assembly can effectively prevent the lateral vibration of the voice coil swing, but its structure directly connected to the voice coil leads to the restriction of the design of the voice coil, and the volume of the magnetic circuit system is also limited, so that the improvement of the acoustic performance of the sound-generating device is limited

Abstract

The invention discloses a sound production device which comprises a basin stand, a vibration system, a magnetic circuit system and supporting skeletons, wherein the vibration system and the magnetic circuit system are respectively fixed to the basin stand; the magnetic circuit system has a magnetic gap; the vibration system comprises a vibration diaphragm fixed to the basin stand, a voice coil fixed to the vibration diaphragm and inserted in the magnetic gap to drive the vibration diaphragm to vibrate to produce sound, and elastic supporting components which are fixed to the basin stand and are opposite to the vibration diaphragm; and one ends of the supporting skeletons are fixed to the corresponding elastic supporting components, and the other ends of the supporting skeletons are fixed to one end of the voice coil, which faces away from the vibration diaphragm so as to elastically suspend the voice coil below the vibration diaphragm. Compared to the related art, the sound productiondevice disclosed by the invention is high in stability and excellent in acoustic performance.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic conversion, in particular to a sound generating device used in portable electronic products. 【Background technique】 [0002] With the advent of the mobile Internet era, the number of smart mobile devices continues to rise.
