Wireless charging magnetic disc (wireless magnetization principle)

• 1, the To wirelessly charge the iphone8 with a sticky patch, which is hot,The phone's not hot. It's been running like this for a minute...
• 2, How to record the best sound in film production
• 3, Can the tablet be placed in front of something magnetic?

Attach the pilot disc to the iphone8 wireless charging, the pilot disc is very hot, the phone is not hot, so rushed for a minute...

1, according to the theoryIt should be affected, because the principle of wireless charging is to generate a magnetic field through the power supply, and then the induction coil in the mobile phone to convert the magnetic into electricity, if there is a magnet sheet, it may complete the magnet sheet heat, there may be a problem. In fact, the phone itself has magnets inside, to achieve some functions, such as wireless charging, will be affected by strong magnets.

2, it is recommended to look at the specifications of the product when selecting the magnetic mobile phone bracket, to ensure that the magnetic magnetic bracket does not exceed the limit of the magnetic insulation range of their own mobile phone, so that it can avoid the failure of the mobile phone due to the magnetic bracket? Professional microphone boom operators know what to do, and most importantly, they know what not to do.

The first chapter deeply discusses the technical basis of film and television and the properties of sound. The first section explains the basic principles and technical elements of film and television production in detail; The second section focuses on the physical characteristics of sound, such as frequency, amplitude, etc. The third section analyzes how sound affects the audience's perception and experience from physiological and psychological perspectives. In chapter 2, we focus on film and television recording equipment.

In the specific situation of film shooting, live radio often can not achieve the ideal effect, or in some virtual scenesThe next voice could not be obtained, so it had to be matched through the later stage, and the profession of mimicry was born. The mimicist can create sounds that match the characters' movements, behaviors, and scenes based on the film and television images. They can find all the materials needed to combine recording equipment and sound field environment to create the various sounds needed in film and television.

Sound and picture counterpoint. 3 sound painting separation. For a long time, the picture and the sound were basically in a synchronized state, and the theme and tone of the picture were exactly the theme and tone of the sound. The mood and mood shown by the sound are also the mood and mood to be shown by the pictureAll the same. The processing means of sound and picture synchronization is one of the most commonly used processing means in film and television art works. The effect of sound in it is mostly an accentuating effect.

The work during the shooting period involves: microphone selection, setting, route determination, recording volume control, recording quality assessment. Post-production includes: transcription, sound cutting, changing vocal cords, mixing (language, sound, music, mixing and optical recording). When a film is released, the sound and picture are printed on an optical material called an optical sound base.

FlatCan the board be placed in front of something magnetic?

1, the magnet does affect the mobile phone, but it must be very strong magnetic will have an impact on some of the functions of the mobile phone. In fact, the phone itself has magnets inside, to achieve some functions, such as wireless charging, will be affected by strong magnets. In addition, the sensors inside the phone, such as the digital compass, will also be affected by the magnet display error.

2, magnetic absorption will not cause damage to the plate, its magnetic principle and magnetic charger is the same, because the original inside the plate is very little iron, iron original is not the main original,The magnet does not have much effect on it, as long as it does not affect the use, it will not affect the performance. The S pole or N pole of the magnet will have an impact on the phone, but the magnetic radiator does not rely on a separate N pole or S pole to attract the metal part of the phone.

3, in the watch, in the movement cover with a soft iron shell can play an anti-magnetic role. As pointed out earlier, the effect of electrostatic shielding is very good. This is because the conductivity of a metal conductor is more than a dozen orders of magnitude larger than that of air, while the difference between the permeability of a ferromagnetic substance and that of air is only a few orders of magnitude, usually about a few thousand times larger. So magnetostatic shielding always has some leakage.

4, electromagnet: When the current through a wire, will produce a magnetic field, resulting in magnetic force. Electromagnets can be used to make motors, loudspeakers and other devices. We can also use electromagnets to make magnetic cranes to move metal objects easily. Magnetic suction cups: This tool is usually used to hold flat glass or other materials on glass. Magnetic suction cups use magnets to hold flat glass firmly to walls or other surfaces.

5, upstairs said too complex, I am a simple magnet to say, certainly has a great impact, thickness.

6, Aragonite note5 screenCurtain bad point, may be around what interferes with magnetic things, to stay away from the mobile phone, the electromagnetic pen around the strong magnet will not write up, it may also be the reason for the magnetic sleeve, take it off. Arashi note5 is a reading tablet released by Arashi.
