1、 Electronic components

1. Oscillator: It is the core component of the alarm clock circuit. It generates a reference oscillation frequency to ensure the stability and accuracy of the entire circuit. This type of component includes different types such as quartz crystal oscillators and ceramic oscillators.

2. Digital integrated circuit: It is the processor of alarm clock circuits and an important part of electronic components. It includes digital clock chips, power management chips, etc., which can calculate and manage time.

3. Other electronic components, such as capacitors, resistors, diodes, transistors, etc., constitute various parts of the circuit and enable it to function properly.

2、 Mechanical gear section

1. Clockwork: It is the power source of a mechanical alarm clock. Increasing the tension of the spring can make the alarm clock run longer.

2. Spindle: It is the core component of a mechanical alarm clock. It can make the clock panel run and complete a certain angle rotation within a certain period of time. The spindle is divided into two types: long spindle and short spindle.

3. Second wheel: It is an important component of a mechanical alarm clock. It can rotate 60 times within a minute and is connected to both the minute gear and the hour gear, causing changes in hours, minutes, and seconds.

4. Other mechanical gears: such as minute gears, hour gears, etc., constitute the mechanical gear system of the alarm clock, which can provide different sizes of force and output different speeds.

3、 Speaker section

The sounder is an important component of an alarm clock, which can produce clear and loud sound. According to different types of alarm clocks, there are various types of speakers, such as scrapers, bells, and bells.
