Abstract
An exemplary electronic device includes a cover, a circuit board and a driving module both mounted on the bottom cover, an electronic component fixed on the circuit board, and a top cover covering the bottom cover. The driving module has a rotating shaft adapted for supportively driving an optical disk to rotate. The electronic component generates heat during operation. Through holes are defined in the top cover and located at a periphery of the rotating shaft. When the optical disk is mounted on the rotating shaft and driven to rotate by the rotating shaft, air heated by the electronic component in the electronic device can flow out of the top cover via the through holes, and rotation of the optical disk facilitates such airflow.
