This is a very popular 4 Tone Generator circuit with an Amplifier Stage. The integrated circuit UM3561 is an outstanding ROM (Read Only Memory) IC. The main function of this chip is to produce different siren tones like Ambulance, Police, machine gun, and Fire brigade siren sound. This IC consists of an oscillator as well as tone selection pins, and it is a low-cost IC mainly designed for toy applications. The designing of this circuit can be done with a few basic electronic and electrical components. For example, a simple siren generator can be built with one external resistor as well as a speaker driver transistor.
