Static electricity detection sound and light annunciator circuit

The circuit is shown in the figure. It consists of electrostatic induction electronic switch and voice sound circuit. When there is an electrostatic field in the environment around the computer, it can detect the presence of static electricity and emit a "beep, please pay attention" sound. At the same time, the light-emitting diode will light up to remind people to pay attention to the safety of the computer or CPU chip.
