ABSTRACT:
A mobile communication terminal with three-dimensional surround-sound effect system has a data processing section for coding and modulating a transmitting signal or demodulating and decoding a receiving signal, and an audio processing section for reproducing an audio signal input from the data processing section or transferring the audio signal input from a microphone to the data processing section. The audio signal has a first audio signal for one speaker and a second audio signal for the other speaker. A first audio path has a first amplifier for amplifying the first audio signal and a first delay for delaying in phase the first audio signal, and a second audio path has a second amplifier for amplifying the second audio signal and a second delay for delaying in phase the second audio signal. A voltage measurer measures the voltage of the first and second audio signals. A comparator compares the first and the second audio signals. An audio controller transfers at least one of the first audio signal and the second audio signal for audio reproduction on the basis of the voltages measured in the first and second audio signals.
