According to an embodiment of the present invention, a voltage supply circuit is included in an audio signal processing apparatus. The circuit comprises: a control unit controlling a signal outputted by a terminal; a power unit outputting voltage to an earphone device depending on a control signal of the control unit; and a variable circuit unit coupled to the power unit to convert the voltage outputted by the power unit to transmit the converted voltage to the earphone device. The purpose of the present invention is to reduce a pop-up effect when a terminal, supporting audio device, supplies a voltage to the audio device. |
