As shown in the figure, the static micro-power dual-tone whistle circuit diagram.
The static power consumption of the circuit is about 150μA before the AN is pressed. Press AN, C1 is charged by D2. When 4 feet are higher than 1V, the 555 and R2, R3, C4 side and functional multivibrator will start to oscillate. The oscillation frequency is about 1000Hz. After releasing AN, due to C3 In parallel with C4, the oscillation frequency becomes lower, and the oscillation frequency is about 700 Hz, so it is two-tone.
