Zusammenfassung:A microphone device, a telephone device and a decoupling circuit are provided. The decoupling circuit includes a first capacitor, a first resistor, and a switch. A first terminal of the first capacitor is coupled to a first terminal of an audio source. A first terminal of the first resistor is coupled to a second terminal of the first capacitor, and a second terminal of the first resistor is coupled to a second terminal of the audio source. A first terminal of the switch is coupled to the second terminal of the first capacitor and the first terminal of the first resistor, and a second terminal of the switch is coupled to the second terminal of the audio source. The first capacitor and the first resistor are used to absorb noise generated by the switch during switching.
