Abstract
Disclosed are an electronic device and a method for controlling the same, where the electronic device that includes an earphone connector including first and second contacts associated with a sound output through an audio plug, a third contact connected to a ground terminal, and a fourth contact associated with a sound input, and a microphone. The method includes applying a bias voltage to the fourth contact, measuring a voltage between the third and fourth contacts, measuring an impedance between at least one of the first or second contact and the third contact, activating the microphone when the measured voltage is greater than or equal to a first threshold value and the measured impedance is less than or equal to a second threshold value, and deactivating the microphone when the measured voltage is greater than or equal to the first threshold value and the measured impedance exceeds the second threshold value.
