Abstract
The present application discloses a heat dissipation device. The heat dissipation device includes a heating element, a sounding device and a heat conductor. The speaker unit includes a diaphragm separating the accommodation space into a front cavity and a back cavity. The housing body is provided with first sound outlet holes communicating to the front cavity. Heat generated by the heating element is transferred outside along with an air flow in the front cavity. The heat dissipation device provided by the present application has the advantages of being good in heat dissipation effect and exquisite and compact in structure and capable of meeting the demand of miniaturization of the heat dissipation device.
