Efficient electronic mouse trap circuit

Shown is a simple and efficient electronic mousetrap circuit
. The red and black terminals are connected to the metal grid respectively, and the gap between the grids is 2cm. When a mouse comes into contact with the energized grid , it will be knocked down and an alarm signal will sound from the speaker. At this time, you can disconnect the power supply and kill the rats to achieve the purpose of eradicating rats.     When using this kind of electronic mousetrap, a special person must be on duty and special attention should be paid to personal safety. A fence must be set up. When people approach, the power must be disconnected first.
