Abstract

The invention provides a loudspeaker box, which includes a housing with a receiving space and a sounding unit fixedly accommodated in the receiving space, the sounding unit and the housing form a closed rear acoustic cavity, and the sounding unit includes a The diaphragm; the shell is made of metal material, and the speaker box also includes an auxiliary cavity shell that is abutted and fixed on the outside of the shell. The auxiliary cavity shell and the shell together form an auxiliary sound cavity, and the shell is provided with a leak port that runs through it. , the leak connects the rear acoustic cavity with the auxiliary acoustic cavity. Compared with the related art, the loudspeaker box of the invention is easy to assemble, has high assembly reliability and good sealing performance.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic conversion, in particular to a speaker box used in portable mobile electronic products. 【Background technique】 [0002] Speaker boxes are widely used in portable mobile electronic products, such as mobile phones, to convert audio signals into sound playback. The speaker boxes are loud and have good low-frequency sound effects. [0003] The speaker box of the related art comprises a front cover, a rear cover which is arranged on the front cover and jointly encloses a storage space, and a sound unit accommodated in the storage space, and the sound unit divides the storage space into Anterior and posterior chambers. [0004] However, in the related art, the front cover and the rear cover of the speaker box are injection-molded, and ultrasonic welding is used to close the sounding unit. Ultrasonic welding requires more volume, thus limiting the volume design of the front cavity and the rear cavity ,...
