Inventor： Chao-Wen Cheng ,  Tsung-Yen Chen ,  Chien Fa Huang ,  Wen Shih Chen ,  Mo-Hsuan Lin

IPC: F24F13/24 ,  G10K11/178

CPC classification number: F24F13/24 ,  G10K11/17823 ,  F24F2013/247

Abstract: In some examples, an electronic device includes an audio output device, an airflow generator to generate an airflow, and a system controller to control an operational speed of the airflow generator. The electronic device further includes an audio controller to generate a noise cancellation audio output based on an indicator of the operational speed of the airflow generator provided from the system controller to the audio controller, and send the noise cancellation audio output to the audio output device to mitigate noise produced by the airflow generator.
