Abstract

A portable communications device includes an interlace 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 connected, 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.

Description

technical field [0001] The present invention relates to a portable terminal having an earphone circuit, and more particularly, to a portable terminal having an earphone circuit capable of classifying the connections of three-pole earphones and four-pole earphones according to the characteristics of each earphone Controls portable terminal functions and headset functions. Background technique [0002] Recently, the complementary functions of portable devices have increased. For example, the portable terminal provides various supplementary features, including: a file playback function for listening or viewing audio files or video files (eg, pre-stored music files and English learning files); and a video camera that can capture photo images or moving images Function. Among these functions of the portable terminal, the file playing function, especially the audio file playing function or the calling function, is to play various audio files stored in the portable terminal and ou...
