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 at 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 provides a sound-generating device, which includes a pot frame, a vibration system fixed on the pot frame and a magnetic circuit system with a magnetic gap; the vibration system includes a diaphragm fixed on the pot frame, inserted in the magnetic gap to drive the vibration The voice coil that produces sound through membrane vibration and the elastic support assembly that is fixed on the basin frame and is opposite to the diaphragm and arranged at intervals, is characterized in that the sound-generating device also includes a support frame; the voice coil is fixedly connected to the diaphragm, and the support frame is close to one end of the diaphragm It is arranged at a distance from the diaphragm, and the end away from the diaphragm is connected to the elastic support component. The support frame is fitted and fixed on the side of the voice coil, and the support frame is used to elastically suspend the voice coil under the diaphragm. Compared with related technologies, the sound-generating device of the invention has good acoustic performance and high reliability.

Description

【Technical field】 [0001] The invention relates to the field of sound and electricity, 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.
