Abstract
The present invention provides a heat dissipation device having a speaker box, a heating element and a heat conductor. The speaker box includes a housing having sound outlet hole and a speaker unit housed in the housing. The speaker unit includes a diaphragm. The heat conductor includes a first heat conductor and a second heat conductor; the first heat conductor includes a heat conductive part, a heat conductive part, and an extensional heat conductive part. The second heat conductor is connected to the extensional heat conductive part at one end and to the heating element at the other end. The heat conductor of the present invention introduces the heat generated by the heating element into the front cavity and transfers the heat through the air in the front cavity to the outside of the sound outlet hole, with a high heat dissipation efficiency.
