[0043] The model of the first control chip is SZY89F. The first capacitor, the second capacitor and the third capacitor are all filter capacitors. The model of the first transistor is KRC106.

[0050] Specifically, in the specific embodiment of the present utility model, as Figure 2-Figure 3 As shown, the third socket J3 provides power and USB D+ signal for the entire circuit. The first media interface connector MIC1 is a sampling sound microphone. The second control chip U2 reads the USB2.0 D+ signal through the third socket J3 plug to determine whether the current computer is turned on or off. The eighth pin of the second control chip U2 outputs a signal for the tenth pin of the first control chip U1 to identify and judge. The first transistor Q1 is a transistor switch, which is turned on to connect the SW+ pin to the GND ground. The sound sampled by the thirteenth pin of the first control chip U1 from the microphone of the first media interface connector MIC1 is compared with the sound inside the first control chip U1 (IC). When the sound is consistent, the ninth pin of the first control chip U1 responds to the action to give the first transistor Q1 a high base level, so that the first transistor Q1 switch is turned on and the SW+ pin is turned on to GND, thereby turning on or off.
