Abstract

A diaphragm provided by the present invention comprises a vibration part and a spherical top part fixed on the vibration part, and the vibration part is made of a rubber compound and comprises a folding ring part, a first fixing part extending from the inner side of the folding ring part and a second fixing part extending from the outer side of the folding ring part. The spherical top part is fixed at the first fixing part, and the folding ring part comprises a plurality of arc-shaped folding ring units which recess along the vibration direction of the diaphragm, wherein the recessing directions of the two adjacent folding ring units are reverse. The present invention also provides a sounding device which comprises a basin stand and the above diaphragm provided by the present invention and fixedly supporting the basin stand. Compared with the prior art, the diaphragm of the present invention is good in consistency, small in distortion and high in stability, and the sounding device applying the diaphragm is good in acoustic performance.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of sound and electricity, in particular to a vibrating membrane and a sound-generating 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 high-quality music function. Therefore, sound-generating devices for playing sounds, such as speakers, are widely used in current smart mobile devices. [0005] The existing sound-generating device includes a basin frame, a vibration system fixedly accommodated in the basin frame, and a magnetic circuit system, through which the magnetic circuit system drives the vibration system to vibrate to produce sound, and the vibration system includes Th...
