Abstract
A rear side of a vibration part of a speaker is covered by a cover member, and a duct is provided at the cover member. The cover member has a recessed portion, and an air flow path is formed inside the recessed portion. A circuit part is mounted on an outer surface of the cover member, and a heat sink provided in the air flow path is connected to the circuit part to allow heat conduction. Due to vibration of the vibration part, an airflow in the air flow path is accelerated and thus the effect of dissipating heat from the heat sink is increased.
