Abstract

The invention provides a loudspeaker box, and the loudspeaker box comprises a shell with an accommodating space and made of a metal material, a sound production monomer, a bracket made of a metal material and a sound guide piece; the sound production monomer, the bracket and the sound guide piece are respectively accommodated in the accommodating space, the sound guide piece is fixedly connected to the bracket, and the sound production monomer comprises a vibrating diaphragm; the shell is provided with a sound outlet; the support is provided with a receding opening opposite to the sound outlet, the sound guide piece is located between the receding opening and the sound outlet, the two opposite sides of the sound guide piece are fixedly welded to the shell and the support respectively, andthe sound guide piece is arranged around the sound outlet and defines a sound guide channel together with the shell. The side, provided with the vibrating diaphragm, of the sound production unit is supported and fixed to the support and spaced from the shell, a front sound cavity is defined by the sound production unit, the support and the shell jointly, and the front sound cavity communicates with the sound outlet through the sound guide channel to form a side sound production structure. The bracket, the sound guide piece, the sound production single body and the shell jointly enclose a rearsound cavity. Compared with the prior art, the loudspeaker box is excellent in low-frequency acoustic 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 ,...
