摘要：
An electronic device includes an enclosure for the electronic device and a fan to create an airflow for cooling electronic components contained in the enclosure. A port extends from an interior to an exterior of the enclosure and is arranged to allow airflow to pass therethrough, where the port comprises a port duct and an end having curved lips. An active noise control device detects a noise generated by the fan and generates an acoustic wave to reduce the noise.
