1, if the protective cover is usedAfter a long time, do not want to use or want to change the protective case after taking it off, then you can directly destroy the protective case, just cut it with a knife. But it should be noted that to control the strength, do not let the knife destroy their headphones, such as marking marks, which is not worth the loss. Soften the case with white vinegar, then slowly remove it.
2, you can use tools to pry open the edge of the protective shell, and then slowly pick out, if the protective shell is no longer used, you can try to use scissors to cut the protective shell from the edge; You can connect the charging cable, then press and hold the charging head to push out the protective case. Bluetooth headset is a combination of Bluetooth technologyUsed on hands-free headphones, users can avoid annoying wires and easily talk in a variety of ways.
3, if the earphone storage shell fell under the bed, in the deep, you can not get it, then you can use a long pole or the kind of hook to make your own, hook it up is also OK.
4, listen to the above said so much, but the most important thing is to personally listen, this is the most critical link. When listening, try to choose a better program source to listen to, do not use the kind of inferior playback source, because it is not good or bad to hear. Only your ears can tellIt is used with magnetic protective cover, magnetic back clip battery, magnetic card bag, magnetic wireless charge, magnetic vehicle support and other magnetic peripheral accessories. The IPhone 13 comes standard with MagSafe magnetic wireless charging system, which supports up to 15W magnetic wireless charging and is compatible with the Qi 5W universal wireless charging standard.
2, maybe the sapphire accuracy on the iPhone camera is not pure, under the Mohs hardness of 6 carving knife test, there will be more obvious scratches, normally sapphire to Mohs hardness of 8 will have scratches.
3, not press the side screen twiceInstead, press the power button twice to first open the Settings in the phone. Find the face ID and password. Enter your password to open Face ID's license iTunesStore and AppStore. Then I went back to the AppStore. Find an APP to download, it will prompt you to press the power button twice, not the screen, you can identify the face installation.
2, electromagnets can produce suction, also known as electromagnetic force. The size of the attraction produced by the electromagnet is mainly related to three factors: the size of the current through the electromagnet, the number of turns of the electromagnet coil, whether the internal contains an iron core, and the general electromagnet contains an iron core. When the electromagnet coil turns more, through the electromagnetThe greater the current, the greater the pull of the electromagnet.
3, magnets adsorbed to each other may also damage the magnet itself due to collision (knock off corners or crack). Keep magnets away from items that are easily magnetized, such as floppy disks, credit cards, computer monitors, watches, mobile phones, medical devices, etc. The magnet should be kept away from the pacemaker. For larger magnets, plastic or cardboard gaskets should be added between each piece to ensure that the magnets can be easily separated. Magnets should be stored in a dry, constant temperature environment as far as possible.
4, there are two ways to improve suction: one is to increase the adsorption area. For example, when an iron plate absorbs a magnet, the larger the area, the stronger the suction. The second is to improve the air gap flux density, which can reduce magnetic leakage through multi-pole magnetization. For example, the rubber magnetic sheet through the multi-stage magnetization design, even if the magnet performance is low, it can also reduce the magnetic leakage through the dense magnetic field distribution and magnetic circuit closed loop.
5, obviously is impossible; If x=y, it means that the effect of the object on the magnetic field makes the suction force of the iron nail 0, and the object is not a magnet, nor is it a magnetic metal such as iron, even if it is a magnetic metal, it must have enough thickness and a completely closed magnetic circuit structure, and the problem only says that it is placed on the iron nail and the magnetHowever, "the wider the better" is not "completely closed", so this situation is also impossible.
Inside this year's iPhone12, Apple has added a magnetic component that makes it easier to use some accessories. However, according to the latest reports, the MagSafe magnetic component of the iPhone12 May cause damage to the access card, magnetic card and other devices placed together, so that it is demagnetized. Therefore, in order to protect your magnetic card, do not put the iPhone12 with some magnetic cards.
So he suggested that this kind of card can be stored in a leather card case, which is an emergency solution for the iPhone 12 specifically to solve this problem, it has an internal shielding function, but the leather card case is priced at 479 yuan. In a recent episode of the Rich on Tech podcast, Apple Vice President Drance addressed customer concerns about the iPhone 12's MagSafe magnetic absorption wireless charging feature. He admitted, iPhoThe magnets on the back of the ne 12 May have an effect on some bank cards, possibly causing magnetic weakening or demagnetization.iPhone12 will make your room card passport degaussing A new selling point of the newly released iPhone12 series is support for MagSafe magnetic wireless charging. According to the official website, users can provide up to 15W wireless charging for the iPhone 12 series through the new MagSafe magnetic accessory, and when you use it, regardless of the location of the device, the magnetic feature will make your iPhone and MagSafe charger fit.
100% does. The harm of magnets to mobile phones is very great, such as mobile phone screen flower screen, mobile phone speaker, handset, microphone degaussing, mobile phone electronic components magnetized, mobile phone antenna magnetized, etc.). It affects the magnet in the handset and can not hear clearly (fatal injury to the handset and speaker of the phone).
The magnet has an effect on the mobile phone, it is recommended not to put the mobile phone and the magnet together. A hundred percent. My factory makes magnets, and I don't even bring my phone to workOn the body. It's in contact with the magnet. The first is to affect the signal, and the second is to affect the magnet in the receiver, so that you can not hear clearly.
You want to ask is the magnet will have an effect on the mobile phone? No. The magnetism of the magnet is very weak, will not have any effect on the mobile phone, the mobile phone itself has magnets, used to achieve some functions, wireless charging, strong magnetic magnets will affect the function of wireless charging. However, for smaller magnets (such as magnetic mobile phone holders), it will not affect the function of the mobile phone.
The influence of the magnet on the mobile phone mainly depends on the strength of its magnetism and the internal components of the mobile phoneDesign. In general, the common magnets in daily life, such as small magnets such as refrigerator magnets, have a relatively weak magnetic force and limited impact on modern smartphones. These phones have been designed with electromagnetic compatibility in mind and can withstand a certain amount of magnetic interference.
