Abstract

The invention provides a loudspeaker box, and the box comprises a shell with an accommodating space and a sound production monomer fixedly accommodated in the accommodating space; the sound productionmonomer and the shell enclose a closed rear sound cavity, and the sound production monomer comprises a vibrating diaphragm for vibration sound production; the shell is made of a metal material, the loudspeaker box further comprises an auxiliary cavity shell which abuts against and is fixed to the outer side of the shell, the auxiliary cavity shell and the shell jointly define an auxiliary sound cavity, the shell is provided with a leakage opening penetrating through the shell, and the rear sound cavity is communicated with the auxiliary sound cavity through the leakage opening. Compared withthe prior art, the loudspeaker box is convenient to assemble, high in assembly reliability and good in sealing performance.

Description

【Technical field】 [0001] The invention relates to the field of electro-acoustic 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 realize the conversion of audio signals into sound playback. The speaker box has high loudness and good low-frequency sound effect. [0003] The speaker box of the related art includes a front cover, a rear cover that is covered on the front cover and jointly encloses a receiving space, and a sound-emitting unit received in the receiving space, and the sound-emitting unit divides the receiving 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 realize the sealing of the sounding unit. Ultrasonic welding requires more volume, thus limiting the vo...
