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.
