| Zusammenfassung: | The utility model provides a circuit capable of removing shutdown noise of an audio system. In the circuit, a control circuit used for monitoring power supply voltage of the audio system is arranged between the power supply voltage of the audio system and output signals of left and right sound channels, and when the power supply voltage of the audio system is lower than a preset value, the output signals of the left and right sound channels are turned off. The circuit capable of removing shutdown noise of the audio system solves the problem of removing the shutdown noise, and perfects the overall performance of display type electronic products with audio devices. |
