Abstract

The invention provides a loudspeaker box. The loudspeaker box comprises a shell, a sound production single body fixedly accommodated in the shell, and an annular bracket which is positioned in the shell and is made of plastic, wherein the sound production single body and the shell jointly form a rear sound cavity, the sound production single body comprises a vibrating diaphragm, and the shell comprises a front cover made of a metal material, a rear cover which covers and is fixed on the front cover and is made of a metal material, and a sound outlet which penetrates through the front cover; the bracket surrounds the sound outlet and wraps the periphery of the sound outlet to be fixedly connected with the front cover, the side, provided with the vibrating diaphragm, of the sound productionsingle body faces the sound outlet, the bracket surrounds the periphery of the sound production single body and is fixed to the sound production single body in a sealed mode, and the sound productionsingle body, the bracket, the front cover and the rear cover jointly define a closed rear sound cavity. Compared with the prior art, the loudspeaker 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...
