ELECTRONIC DEVICE FOR SUPPRESSING NOISE

摘要

An electronic device capable of audio files with different formats includes a power supply, a switching circuit, an audio control module, an audio output module, and a detecting module. The power supply supplies a first voltage and a second voltage. The detecting module detects whether the format of the audio file is changed. The detecting module generates a first detecting signal within a first predetermined time period from a point in time when the format of the audio file is changed time point, and the switching circuit transmits the first voltage to the audio control module in response to the first detecting signal. The audio control module receives the second voltage and generates a first signal based on the first voltage and the second voltage. The audio output module is disabled from outputting audio signal of the audio file.
