Abstract
An electronic device includes an interface unit that communicates with an external device in wireless or wired communication, a resonance sensor unit that detects a frequency resonance signal of the external device, and a controller that detects at least one input from the external device through the resonance sensor unit, determines an audio input or output activation state of the electronic device in response to the communication connection state with the external device, and controls an audio input or output operation of the electronic device based on the detection of the at least one input and the determination of the audio input/output activation state.
