buzzer circuit using 555 IC timer in multisim

circuit works by using a 9-15V battery. 555 IC timer work as Astable multivibrator.
Power is supplied through the Vcc pins of the IC (pin 8), capacitor are connected at the trigger and threshold pins of IC (pin 2 and 6).
Astable multivibrator along with capacitor are responsible for continuously providing High and low signals in the circuit.
The on and off the speed of the buzzer can be controlled through switch used in the Circuit.
The output is at the Pin 3 of the ICs which further goes through capacitor, and finally, the buzzer sound comes 🔊🔊.
