Apple’s iPhone 12 series launch is approaching, and product related information has been fully exposed. In the charging part, wireless charging is the most anticipated thing this year. Charging head network learned from the supply chain that Apple will use magnetic suction wireless charging technology on the iPhone 12, and so far, there is enough evidence to prove the reliability of the message. < / P > < p > shortly after the spy photo of the iPhone 12 magnetic suction wireless charging receiving module, the charging head network once again learned from the supply chain that some insiders had already obtained the suspected Apple iPhone 12 magnetic suction wireless charging protective shell. It can be seen from the photos of the explosion that the protective shell is made of black silica gel and the inner surface is made of superfine fiber, which can protect the body of the mobile phone. The material and design style of this case is consistent with Apple’s previous mobile phone case. < / P > < p > it is worth mentioning that there is a bright ring in the middle of the protection case of the iPhone 12 in spy photos, and the magnetic suction wireless charging structure is built in. < / P > < p > in addition, the iPhone 12 magnetic suction wireless charging protective case in spy photos is printed with two-dimensional code near the camera, and the words iPhone, designed by apple in California, assembled in China and other words are printed on the bottom, which has passed the CE certification. Unfortunately, some important product information about this case has been blocked. < / P > < p > when the inner surface fiber layer of the protective shell is removed, the internal magnet is clearly visible. There are 36 magnets in the ring part, which are arranged in order and fixed by glue. At the same time, there are two square magnets around the ring magnet. The magnet layout of the whole protection case is consistent with the previously exposed iPhone 12 magnetic suction wireless charging and receiving module, except that the protective shell does not have a wireless charging and receiving coil. < / P > < p > the reason why Apple has added so many magnets into the mobile phone case is that for the magnetic absorption wireless charging, the traditional mobile phone protective cover will affect the magnetic strength to a certain extent, thus affecting the alignment accuracy. By adding a magnet, the magnetic reduction of the mobile phone can be avoided and the alignment effect can be ensured. < / P > < p > the charging head network mentioned in previous articles that the magnetic pole staggered arrangement is adopted for the iPhone 12 magnetic suction wireless charging. However, the latest news shows that the magnetic pole arrangement of the wireless charging protective shell is not the same, but each small magnet has multipolarity, and one magnetic surface has both the South Pole and the North Pole. < / P > < p > it can also be inferred that the built-in magnetic suction wireless charging module of iPhone 12 should be arranged in a similar way, because only in this way can the two match each other and enhance the magnetic absorption effect. < / P > < p > from the current exposure of the magnetic suction wireless charging module and the magnetic suction wireless charging protection case, it has become an established fact that the iPhone 12 is equipped with the magnetic suction wireless charging function. The combination of magnetic suction function and wireless charging makes it more convenient for mobile phone wireless charging. At the same time, it can help cultivate users’ wireless charging habits and lay a foundation for future non porous design of mobile phones. < / P > < p > at the same time, existing information shows that Apple’s application of magnetic suction wireless charging function on iPhone 12 has high technical barriers. Based on Qi standard and by adding magnets, the mobile phone wireless charging positioning is more accurate. So the third-party wireless charging accessories manufacturers should first solve the problem of compatibility. As a mobile phone case manufacturer, the appearance of the product is no longer the first factor. IPhone 12 has very high requirements on the precision of the mold and the order of magnets, which completely subverts the traditional mobile phone case industry, and makes a seemingly simple mobile phone protective case bring a strong technological color.
