Sound device

Abstract

The invention provides a sounding device, which comprises a basin frame, a vibration system and a magnetic circuit system with a magnetic gap; The vibration system comprises a diaphragm fixed to a basin frame, a voice coil driving the diaphragm to vibrate and produce sound, an elastic support assembly fixed to the basin frame and opposite to the diaphragm and arranged at intervals, and a support framework spaced apart from the voice coil, wherein one end of the support framework is connected with the diaphragm, and the other end thereof is connected with the elastic support assembly; The support skeleton comprises two, two support skeletons are respectively located on opposite sides of the voice coil, the voice coil is rounded rectangular and comprises four straight edges and four roundedcorners respectively connecting two adjacent straight edges, and the support skeleton is arranged opposite to the straight edges of the voice coil and the rounded corners at both ends of the straightedges. Compared with the related art, the sounding device of the present invention has good stability and excellent acoustic performance.

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. 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, the sound generating devices for playing sound are widely used in smart mobile devices such as mobile phones. [0003] The sound-generating device in the related art includes a pot frame, a vibration system fixed to the pot frame, and a magnetic circuit system that drives the vibration system to vibrate and sound; the vibration system includes a diaphragm fixed to the pot frame, a drive A voice coil that vibrates and emits sound from the diaphr...

Problems solved by technology

[0004] However, in the sound-generating device of the related art, the diaphragm and the elastic support assembly are respectively fixed at 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
