Like tuning forks, quartz crystal vibrates regularly when it is affected by battery power.
Quartz crystal vibrates 32,768 times per second. We can design a simple circuit to calculate the number of times it vibrates. When it counts to 32768 times, the circuit will send out a message and let the second hand go forward for one second.
Because quartz vibrates fairly regularly, even cheap quartz watches do not have an error rate of more than a second in a day.
Quartz watches can also be called "quartz vibrating electronic watches" because they use the "vibration phenomenon" of quartz wafers.
When quartz receives external applied voltage, it will have the property of deformation and expansion. On the contrary, if quartz is compressed, it will generate electricity at both ends of quartz. This property can also be seen in many crystals, called "piezoelectric effect".
Quartz watches use periodic and continuous "vibration" crystals to bring us accurate time.
Firstly, if the quartz plate in the quartz meter is charged, the quartz will vibrate correctly with a cycle number of 32768 Hz; then the frequency must be converted into a signal current cycle number of 1 Hz (a change of current in one second). The second hand on the watch will start with the signal current, and then the minute hand will start. Then the time hand will jump, which is related to the principle of mechanical structure. For example, the minute hand will jump 60 times, and the minute hand will jump.
All quartz watches are equipped with a battery. It provides energy for an integrated circuit and a quartz resonator, which vibrates 32768 times per second. There's something quicker than that. Integrated circuits are the "brain" of tables. It controls the vibration of the quartz resonator and acts as a frequency divider. The 32768 vibrations were split in half 15 times to produce one pulse per second. With "raw materials" at this time of a second, clocks and watches can be driven.
The application of quartz crystals has enabled watches to be produced in large quantities, not only at a much faster rate than before, but also at a lower price. About 500 million watches can be manufactured annually for global use.
