Abstract: Various exemplary embodiments relating to the recognition of earphones by an electronic device are described. An electronic device may include a connector into which an earphone plug is insertable, an audio module configured to process a sound signal, a first circuit configured to connect the audio module with a first terminal of the earphone plug, a second circuit configured to connect the audio module with a second terminal of the earphone plug, a switch configured to connect the first circuit with the second circuit, and a processor configured to perform control to output a first signal from the audio module through the second circuit when the earphone plug is inserted into the connector and configured to determine a type of the earphone plug inserted into the connector based on whether the output first signal is received by the audio module through the switch and the first circuit.

Abstract: An electronic device is provided. The electronic device connects to an earphone. The electronic device includes a connector into which an ear jack of the earphone is inserted, an audio controller configured to process an acoustic signal, a processor configured to control the audio controller, and a memory configured to functionally connect with the processor. The audio controller outputs a first acoustic signal through an ear speaker of the earphone, if an insertion interruption occurs according to insertion of the ear jack. The processor determines a type of the ear jack according to a second acoustic signal collected through an ear microphone included in the earphone.

Abstract: An electronic device, a method for controlling the electronic device, a recording medium, and an ear-jack terminal cap interworking with the electronic device are provided. The method includes determining whether an ear-jack terminal cap has been inserted into an ear-jack terminal provided in the electronic device, setting at least one function for a button of the ear-jack terminal cap, and performing the set at least one function, upon receipt of an input of the button of the ear-jack terminal cap.
