There are many types of clocks, mechanical, quartz, electromagnetic...

1. The mechanical one is to make it move through the clockwork. In mechanical clocks, it is a mechanical mechanism that uses the energy emitted by the recovery of deformation from the spring (mainspring) or the gravity of the falling weight as the energy source, and uses the mechanical vibration system as the time reference to measure the time and time period. There are many types of mechanical watch mechanisms, but they are generally composed of a prime mover system, a drive train, an escapement speed control system, an upper dial system and a hand system, and the working principle is basically the same.

In addition, a calendar (or double calendar) mechanism is included in calendar watches, and an automatic strip mechanism is also included in automatic watches.

2. Quartz.

How quartz alarm clocks work.

Quartz alarm clock can also be called a crystal vibration electronic watch, because it uses the vibration phenomenon of the crystal piece. When the crystal receives external afterburner voltage, it will have the properties of deformation and expansion, on the contrary, if the crystal is compressed, it will cause electricity to be generated at both ends of the crystal; This property can also be seen in many crystals, known as the piezoelectric effect. Quartz watches are crystals that use periodic and continuous vibrations to bring us accurate time.

First of all, the crystal in the quartz watch is energized, and the crystal will vibrate correctly with a frequency of 32,768 Hz. This frequency must then be converted into a signal current frequency of 1 Hz (one change in current per second). Then increase the amplitude of some signals (due to the weak current generated by vibration), follow some signal currents and then start the rotor gears, the second hand on the watch will be started, and then the minute hand and hour hand will jump according to the principle of mechanical structure, for example: the second hand beats 60 times, the minute hand will jump all quartz watches are equipped with a battery.

It provides energy to an integrated circuit and a quartz resonator, which vibrates 317621 times per second. There's something faster than that. Integrated circuits are the "brains" of the table.

It controls the vibration of the quartz resonator and acts as a divider. The 32,712 vibrations are split in half 15 times to produce one pulse per second. With the "raw material" of the time of one second of Chuan, it can drive the display.

What is an analog needle display In order to convert the integrated circuit pulse into motion, the analog analog quartz watch is equipped with a speed-increasing motor, including an electromagnetic rotor, which rotates 180 degrees, or one second, every time it is subjected to a pulse. Here the rotor is used in permanent iron. You buy a quartz clock and plug it in and see it.

It depends on the watch.

If it is an LCD display of the table is not.

If it is a mechanical watch, there may be, if this kind of mechanical watch is not wound (such as: ordinary alarm clock), then it relies on magnets and electromagnetic induction to generate power, driving mechanical movement, generally in the form of a hollow cylindrical type.

So it depends on whether you are this kind of little alarm clock.

Who said no, I'm dizzy. I evacuated my house (though it wasn't restored) and it did. It is very small, in a cylindrical shape, and the inside is empty, like bamboo, and the half-warp is about a millimeter. Height 3 mm. If you don't believe it, you can pull it away and see it's just under the needle.

No, if you imagine that the earth is a big magnet, if the watch is equipped with a magnet, the watch hand will not be uniform, and it will not be accurate.

Definitely not, there is this sticker will affect the speed of the watch and mechanical transmission, the watch is not accurate.

It may be used on the timed horn, and see if it can still ring now.

Probably not in the clock.

It fell out of the clock, and it had no effect on the alarm clock, but I just didn't know what it was for.

The working principle of the electronic clock: there is a quartz crystal oscillator inside that looks like a small aluminum rod that emits a pulse every second so the direction of the current changes once a second When the direction of the current changes, a magnetic field will be generated in the coil and the magnet next to it will act to promote the movement of the magnetic sheet and then push the mechanical part The clock of the battery also has a quartz crystal oscillator The battery provides energy and the crystal oscillator controls the period of releasing energy Only when there is a current in the coil The coil has a strong effect on the small magnet in order to convert the electrical energy of the battery into mechanical energy. The crystal oscillator is made of quartz

When you take a closer look at the watch, there must be a crystal oscillator in it, and it looks like an aluminum rod with a length of about 1cm and a diameter of 3mm, have I made it clear? Beg.

The impact is larger. If it is a mechanical clock, it may be that the parts inside it are magnetized, resulting in inaccurate time. In the case of quartz clocks, the magnetic field has an effect on the weak electrical pulses, which also leads to inaccurate time.

The clock should not be placed too close to the household appliances because it is afraid that the magnetic field generated by the household appliances will affect the time.

1.The crystal pins are in poor contact or are reversed. 2.

The crystal oscillator frequency is incorrect, and the crystal oscillator needs to be replaced. 3.Check the quality of the crystal oscillator itself to ensure that it meets specifications.

4.Check the temperature and electromagnetic interference of the surrounding environment to minimize its impact on the crystal oscillator. 5.

A temperature compensation circuit is added to the crystal oscillator circuit to improve frequency stability. There is a problem with the clock source itself, and the crystal oscillator brand needs to be checked or replaced, which is the leading independent domestic brand of Jinhua Chuangjie Electronics, with more than 50 years of scientific research and technical experience, more than 20 years of Taiwanese and Japanese first-line crystal oscillator brand foundry experience and a professional FAE engineer team, focusing on crystal oscillator design, research and development, production and sales, providing a full range of crystal oscillator products and one-stop FAE technical services. Welcome to inquire ....

It can be told unambiguously, absolutely no impact!

There are no magnets in the electronic watch, only a movement and an electron, hands, a protective cover and a face.

Because the movement is a motor, if there is a magnetic field interference, it will have an effect.

There is a stepper motor in the electronic quartz meter, which is afraid of strong magnetic field interference and affecting the time.

The rotor of the stepper motor in the quartz watch is a magnet, which I took apart and saw.

The rotation of the clock is driven by the magnetic field generated by the coil, and the clock does not move when the magnetic field is constant.

Metal clock manufacturers should follow the positive and negative device batteries on the clock shell and do not use metamorphosed batteries or invert the positive and negative poles of the battery.

Carefully align the timing and time, pull out the handle of the needle and spoon outward, and dial it up for 5 minutes according to the specification and then reverse the alignment. When reversed, the scale of the hour hand rotation shall not exceed the lead position carried by the needle, so as not to damage the internal machine. Keep it clean inside and out.

Do not close the clock case casually, and do not put the clock in a wet, dusty, sooty place, so as not to enter the machine and affect the time.

If the case is plastic, avoid sun exposure and contact with organic oils and other harmful chemicalsIf the clock case is metal, it should be wiped with a soft cloth often to avoid oxidation of the plating layer and fading and rusting of the paint layer. Solve the stop clock in time.

If the clock is stopped during use, it should be reviewed whether the positive and negative poles of the battery can be installed incorrectly, whether the battery can be used up, and whether there is dust or oxidation on the surface of the battery clamp. If you find that other parts are faulty, and you do not control the repair skills, do not disassemble it yourself, so as not to damage the movement. How to use and protect wall clocks, grandfather clocks, alarm clocks, daily clocks There are differences between wall clocks, grandfather clocks, alarm clocks, etc.

The wall clock should be hung upright, and the grandfather clock and alarm clock should be flat. Do not place your watch in a damp and dusty place (if it is necessary to place it in such a place, it should be covered);

There is no need, do not close the bell. Because the internal parts of the clock and watch are exposed to water vapor, they are easy to rust, rust or dust, which will make the parts ineffective and incorrect.

Don't put your clocks in places that are too cold or too hot. In winter, if the clock is placed in a place with more than minus 10 degrees, the oil of the machine will be easily thawed, and the parts will easily shrink or even fall off. If it is too hot, the temperature of the air in the clock will rise, water vapor will occur, and the parts will rust.

And don't put your clock in a place where it can easily be shocked, lest it break the shaft tip. The main parts of metal clockmakers are the mainspring that is the source of energy and the shaft tip that supports the rotation of the gears. The mainspring is made of brittle steel and can break easily, so be careful not to wind it too hard and too tightly.

It is best to be able to put on the strip at a regular time; How many stools you go up each time, you should also have a certain number, and go up at a time, not a few times at any time. When dialing the point, it should be dialed in the same direction, that is, according to the direction of the needle. If it is reversed, it should be dialed a little, and then slightly dialed to the right place at the right time.

This will allow the gears to mesh properly and avoid inaccurate walking.

Magnets must be used in the phone, such as speakers or headphones, but other components can be shielded from the magnetic shield. This one has a proven technology.

If there is a magnet in the phone, the color of your phone's screen will have a large color difference, and there may be color mixing in serious cases.

There are magnets inside the phone, such as speakers.

The loudspeaker is a transducer that converts electrical signals into acoustic signals, and the performance of the loudspeaker has a great impact on the sound quality.

The loudspeaker is the weakest component in the audio equipment, and the loudspeaker is the most important component for the acoustics. There is a wide variety of speakers, and they vary greatly. Audio electrical energy produces sound through electromagnetic, piezoelectric, or electrostatic effects, causing its paper cone or diaphragm to vibrate and resonate (resonate) with the surrounding air.
