Sound output system and method of a mobile communication terminal

A sound output method of a mobile communication terminal including a sound output system comprising a plurality of amplifiers and a plurality of speakers connected to the amplifiers, respectively, the method comprising the steps of:

• determining sound output modes according to a sound signal output;
• when the determined sound output mode is a mono mode, outputting a sound signal to only one of the plurality of amplifiers;
• when the determined sound output mode is a stereo mode, dividing a sound signal to be output into a plurality of sound signals for reproducing stereo sound and outputting the divided sound signals through a plurality of amplifiers, respectively;
• and
• outputting the amplified sound signals through corresponding speakers.

A sound output system of a folder-type mobile communication terminal, the sound output system comprising:

• a sound signal reproduction system for reproducing a sound signal to be output by the mobile communication terminal;
• a plurality of amplifiers, each of which is connected with the sound signal reproduction system and amplifies the sound signal input from the sound signal reproduction system;
• a plurality of speakers, each of which is connected with at least one of the amplifiers and outputs the sound signal amplified by each of the amplifiers;
• and
• a control section for determining whether a sound output mode is a mono output mode or a stereo output mode when the sound signal is generated, and then, if the determined sound output mode is a mono output mode, outputting the sound signal through only one of the plurality of amplifiers, and if the determined sound output mode is a stereo output mode, dividing the sound signal to be output into a plurality of sound signals for reproducing stereo sound and outputting the divided sound signals through a plurality of amplifiers, respectively.
