Hello, electronic clocks are usually composed of the following structures:
1. Main control chip: responsible for controlling the timing and display functions of the clock, generally using a microcontroller or clock chip.
2. Indicator: used to display the part of the time, the common digital display tube, liquid crystal display screen and so on.
3. Clock circuit: including oscillator and frequency divider and other circuits, used to produce stable clock signals.
4. Power circuit: Provide the power required by the electronic clock, generally using batteries or external power adapters.
5. Key switch: used to adjust and set the time, alarm clock and other functions.
6. Housing and panel: used to protect and secure electronic components, while providing an operating interface.
7. Other auxiliary components: such as sound generator, alarm clock alarm, etc. are used to increase the function and use experience of the clock.
