Problems solved by technology

[0006] However, in the sound-generating device in the related art, the thickness of the diaphragm is the same at all positions after molding. For some products, the structural strength of the diaphragm with the same thickness at different positions is not the same, which cannot meet the needs of actual products. The rigidity and other requirements required at a specific position make the diaphragm easy to discount and cause poor performance

Abstract

The invention discloses a vibrating diaphragm which comprises a flat-plate-shaped vibrating part and a folded ring part which is bent and extends from the periphery of the vibrating part and surroundsthe vibrating part, the cross section of the folded ring part is arc-shaped, the folded ring part comprises an upper surface and a lower surface which are oppositely arranged, and the thicknesses ofpart of positions of the folded ring part are different. The invention further provides a field sound generating device applying the vibrating diaphragm. Compared with the prior art, the vibrating diaphragm and the sounding device are good in acoustic performance and reliability.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of electroacoustic conversion, in particular to a vibrating membrane and a sounding device used in portable electronic products. [0003] 【Background technique】 [0004] With the advent of the mobile Internet era, the number of smart mobile devices continues to rise. Among the many mobile devices, the mobile phone is undoubtedly the most common and portable mobile terminal device. At present, the functions of mobile phones are extremely diverse, one of which is the function of high-quality music. Therefore, sound-generating devices for playing sound are widely used in current smart mobile devices. [0005] The sound-generating device in the related art includes a pot frame, a vibration system respectively 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 and inserted into the A magnetic gap to drive the diaphragm to vibr...
