Abstract
An output controller and an method for outputting a signal flow to one or more earphone jacks according to a connection status of each earphone jack. The output controller includes an interface unit having more than one earphone jacks and an output control unit. The output control unit includes a signal input terminal for receiving a signal flow, a detector, and a determining module. The detector detects whether each earphone jack is connected with an earphone and outputs one or more detected signals representing the connection status of the earphone jacks. The determining module outputs the signal flow directly to the connected earphone jack if only one earphone jack is connected to the earphone or distributes the signal flow being amplified correspondingly into each connected earphone jack if more than one earphone jack is connected to the earphones.
