Abstract: An electronic device is provided. The electronic device includes an interface, and a processor configured to receive an input of a user, output an audio signal by using a first external device connected to the electronic device through the interface, in response to the input of the user, obtain an audio signal reflected on a part of the user of the outputted audio signal, by using the first external device, authenticate the user by using the reflected audio signal and execute a specified function in a unlocked state of the electronic device when the user is a user authenticated for the electronic device.

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.
