Abstract: 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.

Abstract: A computer device and a multi-computer system are provided. The computer device includes a central processing unit (CPU), a wireless connection circuit, and a switch circuit. The CPU is coupled to a display to provide an enabling display signal to the display according to a hot plug detection signal provided from the display. The wireless connection circuit receives one of a wireless connection signal and a wireless disconnection signal from a wireless input device. The switch circuit is coupled between the display and the CPU and coupled to the wireless connection circuit. The switch circuit provides the hot plug detection signal to the CPU when the wireless connection circuit receives the wireless connection signal, and masks the hot plug detection signal from the CPU when the wireless connection circuit receives the wireless disconnection signal.
