Abstract
The present application discloses a speaker device including a speaker box, a heating element and a heat conductor. The speaker box comprises a housing and a speaker unit provided with a diaphragm arranged in the housing. The housing comprises a plastic member provided with a through hole and a metal clamping plate. The housing further comprises a sound outlet channel jointly forming a front cavity with a front acoustic cavity. Heat transferred by the heat conductor is conducted to the front cavity, and heat dissipation of the heating element is achieved by means of an air cooling effect formed by air flow in the front cavity.
