The sound principle of electronic alarm clock

The electronic alarm clock is controlled by a chip. The chip is controlled by a small program called a counter. After counting, the binary numbers generated by the encoder and decoder will be transmitted to turn on the semiconductor equipment and the speaker will sound. Clockwork: A device in the engine that winds up a…

Wall clock time adjustment function

The time adjustment of the wall clock is mainly realized by the internal fine-tuning capacitor. Its function is similar to the speed adjustment needle of a mechanical clock. It is designed to eliminate the error of the resonant frequency of the quartz crystal and the influence of the distributed capacitance on the oscillation frequency. It…

Precautions for wall clocks

1. Hang on drywall to prevent moisture from entering the movement, causing a short circuit of the circuit board and corrosion of the electronic parts of the movement. 2. Do not open the back cover of the quartz clock movement arbitrarily, so as to prevent dust from entering the movement and adsorbing on the rotating…

Why are wall clocks so durable?

The pure mechanical clock, clockwork power. With minimal wear and tear during daily use, it is particularly durable. Then coupled with the usual maintenance of the wall clock, the more durable the wall clock will be if it is used correctly.
