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

Abstract

The invention provides a speaker box which comprises a shell and a sound production monomer fixedly accommodated in the shell, and the sound production monomer comprises a vibrating diaphragm for vibration sound production, and the shell is made of a metal material; the shell comprises a front cover and a rear cover which respectively cover two opposite sides of the sound production monomer alongthe vibration direction of the vibrating diaphragm, an annular first bracket fixed in the shell, and a sound outlet penetrating through the shell along the direction vertical to the vibration direction of the vibrating diaphragm, and the first bracket is fixed on the front cover; the side, provided with the vibrating diaphragm, of the sound production unit is supported and fixed to the first bracket and spaced from the front cover, a front sound cavity is defined by the sound production unit, the first bracket and the front cover jointly, the front sound cavity is communicated with the outsidethrough the sound outlet to form a side sound production structure, and a rear sound cavity is defined by the sound production unit, the bracket, the front cover and the rear cover jointly. Comparedwith the prior art, the speaker box is large in cavity size and good in 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, 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 c...
