The multivibrator circuit with variable pitch is composed of two 555 time base circuits, it can issue wave of oscillation changed in 400~2500Hz, and its sound is similar to the sound of the public security police. The circuit consists of power-delay, low-frequency oscillator and the modulation generator.
