Abstract
The present invention provides a speaker box including a housing body with a containment space and a sounding unit. The housing body includes a sound aperture. The sounding unit includes a vibration system with a vibration diaphragm and a magnetic circuit system. The vibration diaphragm divides the containment space into front cavity and rear cavity. The speaker box includes a breathable separator located in the rear cavity to form a sound absorbing cavity. The lower housing includes a bottom wall and a side wall bent and extended from the bottom wall. The breathable separator includes a fixed part fixed to the upper housing, a breathable part having several air circulation holes, and a sealed part extending from the breathable part and sealing the through hole. The speaker box of the present invention effectively reduces the height of the product and reduces the cost.
