DEVICE AND A METHOD FOR REPRODUCING AUDIO DATA BY USING A MOBILE COMMUNICATION TERMINAL, SPECIFICALLY CORRELATED TO REPRODUCING AUDIO DATA OUTPUTTED FROM A SOUND APPARATUS BY USING A SPEAKER PHONE FUNCTION OF THE TERMINAL

摘要

PURPOSE: A device and a method for reproducing audio data by using a mobile communication terminal are provided to use a mobile communication terminal as an external speaker capable of reproducing audio data, thereby realizing various functions of the terminal without comprising another external speaker. CONSTITUTION: A cable connects an audio output terminal of a sound apparatus(100) with an earphone jack microphone terminal of a mobile communication terminal(130). A speaker amplifier(120) amplifies audio data, and outputs the amplified audio data to a speaker. A switch(122) immediately outputs the audio data to the speaker amplifier(120) without passing through a CODEC if a speaker control signal is inputted. A controller outputs the speaker control signal if an operational mode of the terminal(130) is set to a speaker mode and the sound apparatus(100) is connected through the cable, and connects the switch(122) with the speaker amplifier(120).
