This article said is a simple sound generator circuit diagram. The principle is simple and very practical. Want more thoroughly grasp the principle, you should understand and be familiar with the major components of the circuit, such as: UM3561 . All audio IC, transistor output in pin 3 be amplified. A 64 ohm speaker can replace instead of 56 ohm resistor and 8 ohm speaker. 2 bar 4 way switch control sound effects. Position 1 (drawing) is a police siren, position 2 is a fire truck, 3 is the ambulance and the effect of the position 4 is a machine gun.

This circuit uses a UM3561 IC to produce four different sound effects.
