< - b.rr/_.) - Introduction
When we talk about clocks, we will definitely think of vibrations. Mechanical watches use mechanical vibration, and electronic watches of course use electrical vibration. The earliest vibration circuit was composed of an inductor and a capacitor, called a circuit, but its frequency stability was not very good. Later, scientists replaced the vibrator with quartz crystal, which greatly improved the frequency stability. Quartz is a regular hexagonal crystal. The thin slices cut in a certain direction on the quartz crystal are called quartz wafers. Quartz wafers have a wonderful characteristic: if mechanical force is applied to the wafer, an electric field will be generated in the corresponding direction. This physical phenomenon is called the piezoelectric effect. When an AC electric field is connected to the plate of the quartz wafer. When the frequency of the applied alternating voltage is equal to the natural frequency of the quartz crystal, resonance will occur. This phenomenon is called piezoelectric resonance. Using this stable vibration characteristic, everyone has invented electronic watches and quartz clocks with extremely high precision.
