Here is a circuit diagram of the sound of Big Ben show. With text to understand the schematic diagram will be more efficient to understand oh. The circuit is simple and very practical. This circuit produces the famous Big Ben's voice. It produces "ding dong" sound when opened. The basic circuit alternating between two frequencies adjustable. This creates a "ding dong" sound. The first IC determines the speed of conversion from one occurrence and frequency of other second IC determines the tone of the final output. By changing the VR1, conversion rate can be adjusted. By changing the VR2 tone can be adjusted. The first integrated circuit (left) at the 1 Hz oscillator . The second IC's tone changes a modulation voltage output of the first integrated circuit.
