APPARATUS AND A METHOD FOR OUTPUTTING AUDIO OF A MOBILE TERMINAL, PARTICULARLY FOR CONVERTING AN AUDIO SIGNAL INPUTTED FROM A PORTABLE AUDIO UNIT INTO A DIGITAL SIGNAL, ADJUSTING, AMPLIFYING AND THEN OUTPUTTING IT TO A SPEAKER OF A MOBILE TERMINAL

摘要

PURPOSE: An apparatus and method for outputting audio of a mobile terminal are provided to allow a user to enjoy music by outputting an audio signal of a portable audio unit by using a mobile terminal without using a speaker. CONSTITUTION: In an audio reproduction mode, an A/D converter(126) converts an analog audio signal of a portable audio unit inputted through an external connection jack(124) into a digital audio signal and outputs it to a controller(100). A CODEC(112) receives a control signal from the controller(100), converts the digital audio signal into an analog audio signal, amplifies the analog audio signal, and outputs the amplified analog audio signal.
