Problems solved by technology

[0004] However, the second skeleton fixing part of the sound-generating device in the related art is fixed on the inner side of the elastic support assembly. This structure makes the adjustment of the ring width of the elastic support assembly need to be controlled by the ring width of the first ring. Due to the limitation of the membrane stiffness of the first ring, the low-frequency performance of the first ring is poor, and at the same time, the vibration of the first ring is also affected by the position of the elastic member, so that the sound-generating device Acoustic performance is poor

Abstract

The invention provides a sound generating device, which includes a basin frame, a vibration system and a magnetic circuit system. The vibration system includes a diaphragm, a voice coil, a skeleton and an elastic support assembly. The outer peripheral side of the first ring is fixed to the frame; the frame includes the frame body, the first frame fixing part and the second frame fixing part; the first frame fixing part is fixed to the voice coil; one side of the elastic support component is fixed to the frame , the other side of the elastic support assembly is fixed to the second skeleton fixing part; the second skeleton fixing part includes a skeleton bending part that is bent and extended from the outer peripheral side of the skeleton body and is bent and extended from the skeleton bending part to the direction of the voice coil The first section of the flange and the second section of the flange are bent and extended from the first section of the flange to the direction of the elastic support assembly, and the end of the second section of the flange away from the skeleton body is fixed to the elastic support assembly. Compared with the related art, the acoustic performance of the sound emitting device of the present invention is better.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic conversion, in particular to a sound generating device used in electronic sound box products. 【Background technique】 [0002] 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. [0003] The sound-generating device in the related art includes a pot frame, a vibration system respectively fixed to the pot frame, and a magnetic circuit system that drives the vibration system to vibrate and produce sound. The vibration system includes a ring-shaped diaphragm, drives the The voice coil, the skeleton and the elastic support a...
