Components :Resistor : R1 1k8 : R2 5k6 : R3 1k2 : R4 100ΩCapacitor : C1 10µF/16V : C2 22µF/16VIC : NE 555Transistor : Tr1 2N 4355Speaker 2Ω 2inchSuch settings it sounds weird, but it was so. This circuit is a circuit that can generate oscillations generated by the components of IC and transistors so as to produce sound with a frequency of 50KHz is quite deafening and at the same mice away.
