Abstract

The invention provides a loudspeaker box, and the loudspeaker box comprises a shell and a sound production monomer fixedly accommodated in the shell; the sound production monomer and the shell jointlyenclose a rear sound cavity, the sound production monomer comprises a vibrating diaphragm for vibration sound production, and the shell comprises a front cover, a rear cover and a sound outlet penetrating through the front cover; the front cover comprises a front cover body, a front cover outer side wall extending from the front cover body and a front cover inner side wall extending from the front cover body. The loudspeaker box further comprises a support, the side, provided with the vibrating diaphragm, of the sound production single body faces the sound outlet, the support comprises a support body and a support extension wall, the inner side wall of the front cover is completely embedded in the support body, and at least part of the front cover body is embedded in the support body; thesupport body is arranged around the periphery of the sound production single body and forms sealed fixation with the sound production single body. The sound production unit, the support, the front cover and the rear cover jointly form 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...
