Abstract: A method and an apparatus for recognizing earphone insertion are provided. In the method, whether an earphone is inserted is determined. When earphone insertion is determined, a discontinuous Direct Current (DC) voltage is applied to a microphone end of an earphone jack. A magnitude of the discontinuous DC voltage of the earphone jack is determined. Whether the earphone jack is a three-pole earjack or a four-pole earjack is determined depending on the determined magnitude of the discontinuous DC voltage. Therefore, erroneous recognition of the earphone insertion may be prevented.
