Abstract: The present disclosure relates to a speaker box. The speaker box includes a housing having a top wall, and a sounding unit accommodated in the housing. The sounding unit includes a diaphragm, which together with the top wall are disposed with a spacing therebetween to form a front acoustic cavity. The speaker box further includes a sound guiding channel. The front acoustic cavity and the sound guiding channel together constitute a front chamber of the speaker box. At least two first through-holes disposed with a spacing therebetween are provided in a region of the top wall corresponding to the front chamber. The speaker box further includes a cover plate provided on the top wall. The cover plate includes hard sheets covering the first through-holes and a soft rubber fixing portion, which surrounds and spaces the hard sheets from the top wall, and is fixedly connected with the top wall.
