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

The invention provides a loudspeaker box and an assembly process thereof. The loudspeaker box comprises a shell and a sound production monomer accommodated in the shell, wherein the shell comprises afront cover made of a metal material, a bracket fixed on the front cover and a rear cover made of a metal material; the support comprises a supporting body made of metal materials and used for supporting the sound production single body and an outer connection body formed on the supporting body in an injection molding mode, the supporting body sinks away from the sound production single body to form a containing groove and defines a front sound cavity together with the sound production single body, the outer connection body is provided with a sound guide channel penetrating through the outer connection body, and the front sound cavity is communicated with the outside through the sound guide channel. The single sounding body, the support and the rear cover jointly form a rear vocal 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 body and 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 ...
