Sound production device

Abstract

The invention provides a sound production device, which comprises a basin frame, a vibration system and a magnetic circuit system. The vibration system comprises a diaphragm, a voice coil, a frameworkand an elastic support assembly, the diaphragm comprises a first folding ring, a second folding ring and a vibration part, and the peripheral side of the first folding ring is fixed on the basin frame; the framework comprises a framework body, a first framework fixing part and a second framework fixing part; the first framework fixing part is fixed on the voice coil; one side of the elastic support assembly is fixed on the basin stand, and the other side of the elastic support assembly is fixed on the second framework fixing part; the second framework fixing part comprises a framework bendingpart which is bent and extended from the peripheral side of the framework body, a first section of flanging which is bent and extended from the framework bending part to the direction of the voice coil, and a second section of flanging which is bent and extended from the first section of flanging to the direction of the elastic support assembly; the end, away from the framework body, of the second flanging is fixed to the elastic supporting assembly. Compared with the prior art, the device has the advantage that the acoustic performance of the sound production device is good.

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...

[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
