Abstract

The invention is applicable to the technical field of sound boxes, and provides an intelligent sound box. The intelligent sound box comprises a base; a casing member fixedly installed on the base and provided with a sound cavity body; a front baffle fixed to the casing member and provided with at least one sound outlet hole communicated with the sound cavity body; at least one loudspeaker fixedly installed in the sound outlet hole; at least one cavity wall thickening layer attached to one side of the casing member deviating from the front baffle, wherein the material of the cavity wall thickening layer is different from the material of the casing member. According to the intelligent sound box, the cavity wall thickening layer is attached to the casing member, so the cavity wall of the sound cavity body is composed of the casing member and the cavity wall thickening layer with different materials, after the sound waves generated by the vibration of the loudspeaker is transmitted by the casing member, a part of energy strongly penetrates through the casing member and is absorbed by the cavity wall thickening layer, and few sound waves penetrate through the cavity wall thickening layer, thereby improving the sound quality and the sound effect of the intelligent sound box, and thus more vigorous, full, generous, mellow sound is obtained.
