1, Yes, do you know the ore radio? That thing has no power source, the energy is the energy of the electromagnetic wave itself, and it must be to convert DC into AC, and the frequency must be high. Rectangular coils of thick copper wire are easier to use, and their magnetic fields are stronger. But the coil is better bought at the component storeAfter all, it is professional. Still do not know can join the QQ discussion group, everyone with you to analyze.
2, round good. Circular coil, the manufacturing shape is relatively simple, the coil is easier to evenly distributed on the surface of the object, so it is more suitable for symmetrical structure. Square coils, its manufacturing difficulty is higher, because the production process needs to stack coils, so that the coils tightly together, otherwise there will be problems such as internal capacitance and inductance loss, so it requires higher skills and precision. Therefore, the two are better than the self-made DC motor coil wound into a circle.
3, to receive the wireless charger transmission of electrical energy. The circleThe loop is actually a coil that transmits power to the device's battery via a bus. When the device is placed on the wireless charger, the coil in the wireless charger creates an electromagnetic field, and when the coil of the device is in contact with it, electrical energy is transmitted to the device through induction, thus achieving the function of wireless charging. Therefore, the circle plays the role of receiving wireless charging electricity.
4, rectangle good. Contactless IC card, also known as radio frequency card, is composed of IC chip, induction antenna, packaged in a standard PVC card, chip and antenna without any exposed part.
2, Step 1: Enter the setting First, circular wireless charge We need to enter the phone's setting interface. Find the "Settings" icon on the home screen and tap to enter. Step 2: Go to Battery Settings In the Settings screen, slide down the screen, find the "battery" option, and tap to enter. Step 3: Enter the Wireless charging Settings In the battery Settings screen, slide down the screen, find the "wireless charging" option, click to enter.
3, once 4, make sure that your mobile phone supports wireless charging model: If you are not sure whether your mobile phone supports wireless charging, you can open the Settings app, and then select the general AboutAirplane. At the bottom of the page, you can see the device model. If your device model is a model that supports wireless charging, then it will display a "Qi charging" after the model name, which means that your device supports the Qi wireless charging standard. 5, take the Apple 13 as an example, in the Settings, the opening steps are as follows: Open the Settings of the Apple 13 phone, slide the screen to look for the "battery" option. Click to enter, you can see the "wireless charging" option, click to open. When using features, make sure that both the phone and charger you are using support wireless charging technology. 6. Specific operationsi Wireless fast charge, the ball diameter of the product is 87mm. 2, after a few years, millet 12 released, support 50W wireless fast charge, so millet launched a new Xiaomi wireless car charger Pro, this wireless car charger just support 50W wireless fast charge, can be said to be born for millet 12, after all, the current market support 50W wireless fast charge mobile phone is millet 12, in other words, This time, Xiaomi wireless car charging Pro will once again lead the new era of car wireless charging. 3, this depends on the maximum wireless charging power. For example, Xiaomi's 20W wireless charge, defaultThe delivery is 27W charging head. Of course, this is the best configuration, low play can not play wireless power, high waste. The charging head is higher than the wireless charging power, because the conversion process has energy loss. 4, millet wireless car charging universal fast charging version adopts electric induction arm, built-in infrared sensor and motor, the arm can be automatically expanded and locked when the phone is near. The arm can reach 85mm after opening, and the phone can be easily put in and charged. You can take it away with one hand by tapping the side button. Mobile power charging cable Connect the mobile phone Micro USB, press the mobile power button can automatically charge. Mobile power supply, (referred to as MPP), a portable charger that integrates power supply and charging functions, can charge or standby power supply for mobile phones and other digital devices anytime and anywhere. mophie dual wireless charging pad Remove the top panel and attach it to the housing using double-sided tape. Unscrew and remove the top cover, inside are two separate wireless charging units. Wireless charging coils and electricityThe circuit board is an independent unit, and the thermistor in the middle of the coil detects the temperature rise during charging. Compare the size of a $1 coin. Coil center thermistor close-up, double-sided tape fixed. Sometimes users want to view the phone screen, they have to pick up the phone, which is not convenient. Mophie recently launched an adjustable Angle wireless charging board, through the use of folding design, in addition to the traditional wireless charger to allow the phone to lay flat, but also like a mobile phone stand, let the phone stand in front of the charging board. Therefore, even if it is charged, it can easily view information, especially when it is placed on the desk or bedside, just turn the headTo view. First, the Powerstation series has a fabric coating and four-lamp LED power indicator, clearly showing the remaining power, whether it is the standard 10,000mAh capacity or XXL 20,000 mAh, to meet your large capacity needs. They are equipped with a USB-C port, which can both charge the battery itself and provide fast charging of up to 18W for other devices, and the USB-A port makes it possible to charge multiple devices simultaneously. mophie round charging pad How to use
Wireless charging forWhat a circle and a little
1. The circle sent by the wireless charger is the charging receiver of the wireless charger. It is placed on the back of a phone or other device that supports wireless charging to receive the power transmitted by the wireless charger. The circle is actually a coil that transmits power to the device's battery via a bus bar.
2, check the bottom of the phone charging hole is blocked by foreign bodies, foreign bodies will cause poor contact, can not be charged. Check whether there is a problem with the charger, you can change a data cable or charging head. You can try to shut down and restart, the system will sometimes fail, resulting in no chargingYes. If the above methods are not possible, there may be a problem with the mobile phone battery, you can go to the maintenance point to repair and replace the battery.
3, iPhone magnetic buckle design. The purple circle inside the phone case acts as a magnet for easy charging. The Magsafe magnetic wireless charging technology introduced by the iPhone 12 actually adds magnets to the traditional wireless charging technology. This technology realizes the precise docking and pairing of the phone and the wireless charger through the attraction of the magnet, reducing the displacement caused by vibration.
4, floating ball is also called auxiliary touch, small white point, smallCircle, virtual home button. Unlock the phone screen, open the phone Settings icon, slide down the screen in the Settings page, click auxiliary function, then slide down the screen, click touch option, then find and click the auxiliary touch option, and finally slide the button on the right of the auxiliary touch to the green state.
