Loudspeaker box and assembly process thereof

Abstract

The invention provides a loudspeaker box and an assembly process thereof. The loudspeaker box comprises a sound production single body, a front cover made of a metal material, an integrally injection-molded bracket fixedly supported on the front cover, and a rear cover made of a metal material, the support comprises a support body for supporting the sound production single body and an external connection body which is connected with the support body and defines an annular through hole. The external connection body is provided with a sound guide channel penetrating through the external connection body. The rear cover covers the front cover and the outer connecting body and defines a shell with an accommodating space together with the front cover and the outer connecting body; the sound production monomer and the support body are accommodated and fixed in the accommodating space of the shell; the front cover, the support body and the sound production single body jointly enclose a front sound cavity, and the sound guide channel communicates the front sound cavity with the outside; and the sound production single body, the outer connection body, the support body and the rear cover jointly form a rear sound cavity. According to the loudspeaker box, the volume of the cavity in the shell can be increased, the volume of the rear sound cavity defined by the sound production single bodyand the shell is increased, and the acoustic performance, especially the low-frequency acoustic performance, of the loudspeaker box is improved.

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 and an assembly process thereof. 【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, the front cover and the rear cover of the loudspeaker box in the related art are injection-molded, and the sealing of the sounding unit is realized by means of ultrasonic welding. Ultrasonic welding requires more volume, thereby limiting ...

Problems solved by technology

[0004] However, the front cover and the rear cover of the loudspeaker box in the related art are injection-molded, and the sealing of the sounding unit is realized by means of ultrasonic welding. Ultrasonic welding requires more volume, thereby limiting the volume design of the front cavity and the rear cavity. which in turn limits acoustic performance
