Portable wireless terminal, method of outputting sound, and method of picking up sound

摘要

A portable wireless terminal provides a signal output circuit for outputting an audio signal to a speaker or to earphones from an earphone jack via a plug, and a controller for controlling the signal output circuit to output an arbitrary audio signal or another audio signal to the speaker and/or the earphones at an arbitrary timing when the audio signal is being outputted to the speaker and/or the earphones. Thereby, an audio signal can be outputted to the desired speaker and/or the earphones that have been arbitrary selected by switching the signal output circuit without pulling the plug out of the earphone jack when the audio signal is being outputted to the speaker and/or the earphones.
