Abstract

The present invention provides a sound-generating device, which includes a vibrating system and a magnetic circuit system having a magnetic gap and driving the vibrating system to vibrate, the vibrating system includes a vibrating membrane for vibrating and sounding; the vibrating membrane includes a vibrating part, A ring part bent and extended outward from the periphery of the vibrating part and a fixing part bent and extended from a side of the ring part away from the vibrating part; the ring part is in a rectangular structure with rounded corners , the ring portion includes two opposite long-axis sides, two opposite short-axis sides and a fillet connecting the adjacent long-axis sides and the short-axis sides; the diaphragm also It includes a fixing boss protruding from the side of the rounded corner away from the vibrating part in a direction away from the magnetic circuit system, and the fixing boss is connected with the fixing part. Compared with the related art, the sound-generating device of the present invention improves the problem of swing and low-frequency distortion when it works.

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] Sound generating devices, also known as loudspeakers or horns, are used in speakers to convert audio signals into sound playback. [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 having a magnetic gap and driving the vibration system to vibrate. The vibration system includes a diaphragm for vibrating and sounding. [0004] However, in the sound emitting devices of the related art, the stiffness of the diaphragm is relatively low, and some products have higher requirements on the stiffness and distortion. The diaphragm structure of the prior art cannot meet the stiffness and distortion requirements of the product. [0005] Therefore, it is necessary to provide a new soundin...
