Abstract

The invention provides a sound production device, which comprises a shell with an accommodating space and a sound production monomer accommodated in the accommodating space, and is characterized in that the sound production monomer comprises a vibrating diaphragm for vibration sound production, and the shell is made of a metal material and comprises a base and a rear shell; the base comprises a base plate, a base extension wall, an auxiliary extension wall and an annular flange edge which is bent and extends from one end, far away from the base plate, of the auxiliary extension wall to the direction close to the sound production monomer; one side, provided with the vibrating diaphragm, of the sound production monomer is propped against and fixed on the flange edge and communicates the vibrating diaphragm with the outside; the sound production device further comprises a support, the support comprises an annular support body and a support extension wall, the support body and the sound production single body are fixed in a sealed mode, and the support extension wall is welded and fixed to the side, close to the rear shell, of the base plate. The rear shell, the base, the support and the sound production single body jointly form a rear sound cavity. Compared with the prior art, the sounding device provided by the invention is good in reliability.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic conversion, in particular to a sound emitting device used in portable mobile electronic products. 【Background technique】 [0002] Sound-generating devices, also known as speakers, are widely used in portable mobile electronic products, such as mobile phones, to convert audio signals into sound playback. The sound-generating devices have large loudness and vibration amplitude. [0003] The sound-generating device in the related art includes a sound-emitting unit for sounding, a base and a rear shell respectively covering the opposite sides of the sound-emitting unit, the base and the rear shell together form a storage space, the base and the The rear shell is injection molded and fixed by ultrasonic welding. [0004] However, if the base and the rear shell of the sound-generating device in the related art need to be fixed by ultrasonic welding, more space is needed, which limits the space size of ...
