Abstract
The present application provides a speaker box device having a speaker box, a heating element and a heat conductor. The speaker box includes a housing body and a speaker unit provided with a diaphragm. The heat conductor includes a first end part connected to the heating element, a second end part and a connection part connecting the first end part to the second end part. Heat of the heating element is discharged by means of an air cooling effect, so that the heat dissipation efficiency of the speaker device is ensured.
