Abstract: An audio device for blocking noise generated in an idle state in an electronic device is provided. The audio device includes a processor configured to output an audio signal, an audio amplifier configured to amplify and output the audio signal output from the processor through an interface electrically connected to the processor, a switching part configured to switch the amplified audio signal output from the audio amplifier to a sound output in response to a switching control signal (EN/DIS), the sound output configured to output the amplified audio signal transferred through the switching part to an outside, and a rectifier configured to output the switching control signal (EN/DIS) for enabling the switching part if there is the audio signal transferred from the processor to the audio amplifier through the interface.
