What is a Quartz Clock?

A quartz clock is an instrument for timing. Everyone is familiar with lifting the clock, it is a kind of timer that tells us the time. In daily life, a clock accurate to 1 second is enough. But in many areas of scientific research or engineering technology, the hour is much higher. Quartz clocks are created according to this need. Its main component is a very stable quartz oscillator. Take out the oscillation frequency generated by the quartz oscillator. Make it drive the clock to indicate the time. This is the quartz clock. At present, the best quartz clocks are accurate to one hundred thousandth of a second every day, which is only 1 second after almost 270 years. But in today's scientifically advanced, this quartz clock has been replaced by other types of clocks (such as radio watches) that are much more accurate.

Radio controlled timepieces, also known as radio controlled timepieces (English name: Radio controlled timepieces). The technical principle of radio timepieces as a system is: first, the standard time signal is encoded by the standard time service center (the commercial code is encrypted), and the low frequency (20KHz-80KHz) carrier is used to transmit the time signal by radio long wave go with. The radio-controlled timepiece receives the low-frequency radio time code signal through a built-in miniature radio receiving system, and the time code signal is demodulated by a special integrated chip, and then the timing mechanism is automatically adjusted by a control mechanism built into the timing device. Through such a technical process, all clocks (or other timing devices) receiving the standard time signal are kept highly synchronized with the standard time of the standard time timing center, and all radio timepieces display strictly consistent time. The working principle of electronic timepieces is designed based on the physical phenomenon of "electromagnetism, magnetoelectricity". That is, the electric energy is converted into magnetic energy, and then the magnetic energy is converted into mechanical energy, which drives the hour and minute hands to achieve the purpose of timing.

1. The transistor balance clock uses a dry battery as the energy source, a transistor as a switch, a balance spring as an oscillation system, a unified movement of J1 type, and the same appearance as an ordinary alarm clock.

2. The crystal alarm clock has the same performance as the transistor balance clock, plus a time alarm device powered by electricity.

3. The transistor pendulum clock uses an electronic circuit to control the pendulum as an oscillating element, and its shape is similar to a mechanical pendulum clock.

4. The quartz clock uses a "quartz crystal" as an oscillator, and the motor is controlled by electronic frequency division to drive the hands. High travel accuracy. Varieties include table clocks, wall clocks, calendar clocks, alarm clocks, music clocks, floor clocks, but also various technical clocks such as car clocks, ship clocks, and astronomical clocks.

5. The digital display clock also uses a quartz crystal as an oscillator, and directly displays the time with a light-emitting tube or liquid crystal without mechanical transmission. With hours, minutes, seconds, calendar, weekly calendar, monthly calendar and other functions.

6. The electronic watch uses batteries as its energy source instead of clockwork. It has various structures and has the same structure as a mechanical watch. They are collectively called electronic watches. According to the structure and the invention, the electronic watch is divided into four generations:

The first generation is a balance spring electronic watch, which uses a balance spring as an oscillator and uses a micro battery as an energy source to drive the balance through electronic circuits.

The second generation is a tuning fork electronic watch, which uses a metal tuning fork as an oscillator and uses electronic circuits to output pulse currents to make mechanical tuning forks vibrate.

The third generation is a pointer quartz electronic watch, which uses a quartz resonator as an oscillator and drives a stepper motor to drive the gear train and hands through an electronic frequency divider.

The fourth generation is a digital quartz electronic watch. It also uses a quartz resonator as an oscillator. The difference is that it uses a display device to display time in digital form after frequency division, counting and decoding. The first three generations of electronic watches have traditional mechanical pointer mechanisms, while the fourth generation adopts large-scale integrated circuits, which is completely out of the traditional mechanical structure of all electronic watches. There are different kinds and different principles, but the changes are inseparable.
