A multivibrator with sirens composed of gate circuit can drive LEDs to generate a great amount of changing colors. Pulse output through multivibrator can drive the speaker to produce sound. Signals with one frequency can make the speaker produce sound with single frequency; Signals with several frequencies can make it produce different sounds. According to this principle, one can have a mix of signal sources with different frequency to obtain the various sounds needed. As shown in the figure l is the siren generator composed of gate circuit.
