The circuit consists of a one-shot trigger and a language integrated audio circuit. 555 and R1, C2, etc. form a one-shot trigger. When the visitor touches the metal piece A, the 555 circuit is set, and the 3rd pin is high level, triggering IC2. IC2 is a language integrated circuit CIC5603. When the pin 2 has a trigger level signal, its internal memory is activated and a sound is heard through the speaker. At the same time, the two LEDs shimmer.
