Abstract
An anti-pop circuit is coupled with a sound outputting device to prevent a 'pop' sound form being mixed into a sound signal. The anti-pop circuit includes a control signal generator and a fist diode. The control signal generator generates a control signal with a high level state and a low level state. The first diode couples with the sound outputting device. The sound signal is transferred to the first diode when said first diode is in a forward bias state, and the sound signal is outputted from an output end of the sound outputting device when the first diode is in a reverse bias state.
