The electronic device includes an audio module, an external audio processing module, a local audio processing module, a switching module, and a setting module. The external audio processing module processes an external audio signal transmitted via a communication channel. The local audio processing module processes a local audio signal. The switching module is connected between the audio module, and the external audio processing module and the local audio processing module. In the first state, the audio module and the external audio processing module are connected. In the second state, the audio module, and the local audio processing module are connected. The setting module is connected to the switching module. The setting module sets the switching module to switch the electronic device to the first state or the second state in response to an input signal.
