Abstract
A method of controlling the output according to a type of connector and an electronic device adapted to the method are provided. The method includes determining whether a first, second and third external connector is inserted into a receptacle, via a circuit connected to the receptacle, wherein the receptacle is configured to receive the first, second or third external connector, each of the first and second connector includes a first number of contacts, and the third external connector includes a second number of contacts less than the first number of contacts; providing an audio output signal to the first external connector in a first manner when the first external connector is inserted into the receptacle; providing an audio output signal to the second external connector in a second manner which differs from the first manner when the second external connector is inserted into the receptacle; and providing an audio output signal to the third external connector in a third manner which differs from the first and second manners when the third external connector is inserted into the receptacle.
