Abstract
The present invention provides a speaker box including a housing having a receiving room and a speaker received in the receiving room. The speaker includes a frame, a diaphragm and a magnetic circuit system supported on the frame. The speaker separates the receiving room into a front cavity for transmitting a sound and a rear cavity. The speaker has a back cavity, and the back cavity is communicated with the rear cavity. The housing includes an outer surface and an inner surface. The housing includes a leakage hole communicating the rear cavity and an outside. The speaker box further includes an air-permeable mesh covering the leakage hole. A size of the leakage hole located on the outer surface is larger than the size of the leakage hole located on the inner surface. The speaker box of present invention can effectively avoid the problem of amplitude deviation during work.
