An audio reproduction circuit of a mobile communication terminal is provided to originally block pop-up noise as a bypass capacitor is not used, thereby ensuring reproduction of high-quality sounds. An amplifier(205) amplifies a predetermined analog signal. A speaker(206) outputs the amplified analog signal. A compensation voltage applier(207) applies a compensation voltage corresponding to a DC(Direct Current) voltage outputted from the amplifier(205) by being connected to one end of the speaker(206). An audio processor(204) converts a digital audio signal into an analog signal. The compensation voltage applier(207) is extracted from the audio processor(204).
