Abstract
A portable communications device includes an interface unit to which a three-pole earphone or a four-pole earphone is connected. The device also includes a controller that activates a microphone function prepared in a terminal body when the three-pole earphone is connected. When the four-pole earphone is connecting, the controller deactivates the microphone function of terminal body. The device also includes an audio processing unit that is configured to output an audio signal to the three-pole earphone or the four-pole earphone under a control of the controller.
Claims20
A portable terminal comprising an earphone circuit, the earphone circuit comprising:
- an interface unit adapted to couple to either a three-pole earphone or a four-pole earphone;
- a controller configured to activate a microphone function prepared in a terminal body when the three-pole earphone is coupled to the interface unit, and configured to deactivate the microphone function of terminal body when the four-pole earphone is coupled to the interface unit;
- and
- an audio processing unit configured to output an audio signal to the coupled earphone under a control of the controller.
A method of operating a portable terminal comprising an earphone circuit, the method comprising:
- determining whether a three-pole earphone or a four-pole earphone is connected to an interface unit;
- and
- at least one of activating a microphone function prepared in a portable terminal body when the three-pole earphone is connected, and deactivating the microphone function of the portable terminal body when the four-pole earphone is connected.
An earphone circuit for use in a mobile communications device, the earphone circuit comprising:
- an interface unit adapted to couple to either a three-pole earphone or a four-pole earphone;
- a controller configured to activate a microphone function prepared in a terminal body when the three-pole earphone is coupled to the interface unit, and configured to deactivate the microphone function of terminal body when the four-pole earphone is coupled to the interface unit;
- and
- an audio processing unit configured to output an audio signal to the coupled earphone under a control of the controller.
