2. Taking RedmiAirDots true wireless Bluetooth headset and Xiaomi Bluetooth headset AirDots Youth edition as an example, Xiaomi wireless headset 99 and 199 are compared as follows: First of all, the color of the two Bluetooth headphones is different, of which the RedmiAirDots true wireless Bluetooth headset color is black, and the Xiaomi Bluetooth headset AirDots youth version color is white.
The current generated by this induction can be used to charge a mobile phone. The charging efficiency of a wireless charger depends on the design of the magnet and coil and the match between the phone and the charger. If the match between the magnet and the coil is not good, or the size of the phone and the charger do not match, then the charging efficiency will be reduced, or even unable to charge.
There are no magnets in the wireless charger. If you place a live wire on a magnetic compass, you can see thisSome electric currents can also produce a magnetic field. If you use a moving magnet instead of an alternating current wire, you're ready. The varying currents in the wires create varying magnetic fields. The changing magnetic field creates an electric current in the other coil. The more loops you create, the stronger the effect.
Apple phone case circle is suitable for magnetic charging. The iPhone 12 series has added Magsafe, which can be used with magnetic accessories, and MagSafe dual chargesAppliances can easily charge compatible iphones, Apple Watches, wireless charging cases for AirPods, and other QI-certified devices. Simply place your device on the charger and it will start charging steadily and efficiently. The charger also folds up so you can take it with you.
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. thisThe technology realizes the precise docking and pairing of the mobile phone and the wireless charger through the attraction of the magnet, reducing the displacement caused by vibration.
The purple circle inside the phone case is the magnetic effect can be used to charge. The new Magsafe magnetic wireless charging technology equipped with iPhone12 can be simply understood as adding a circle of magnets on the basis of the original wireless charging technology. Through the attraction of magnets, the mobile phone and the wireless charger are accurately positioned and paired, while effectively avoiding displacement due to vibration, so that the mobile phone is in a more efficient wireless charging state. Supports up to 15W power.
means to scan the network. The operation method is as follows: First, open the "Settings" in the phone, and find the "WLAN" option in the "Settings", as shown below. Open the [WLAN] option Settings, click the button next to the [WLAN] option to turn on the WLAN network. After turning on the WLAN network, the phone will scan for nearby WiFi signals to find the WiFi signal it wants to connect to.
You may have turned on the wireless hotspot function,It is recommended to turn off this wireless personal hotspot, and there should be no more. That's because the icon looks like a cell tower, meaning that your phone is acting as a wireless network to send out a signal, and other phones can pick up your personal hotspot signal.
WIFI hotspot function. According to the query China Machinery network, there are three circles next to wifi that indicate that the WIFI hotspot function is turned on. Mobile wifi hotspot is a technology that converts GPRS, 3G or 4G signals received by mobile phones into wifi signals sent out.

iPhone magnetic buckle design. The purple circle inside the phone case playsMagnetic action, easy to charge. 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.
If the circle refers to the ring or ring decoration on the shell, because the ring is an integrated design fixed on the shell, it can not be removed separately and used on other shells. If you want to replace a phone case, you usually need to replace the entire phone case, not just one of themParts. New phone cases can be purchased, and they are usually already pre-designed, including the shell, the inner shell, and the corresponding fixed structure.
Universal silicone phone case looks like, is a circle, can be used, Taobao has glow-in-the-dark, Philippines general mobile phone accessories here can see.
If the vivo mobile phone is used, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, the device that needs to be charged and the wireless charging after being energizedThe device can be charged by contact.
Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
Electromagnetic induction: The fundamental principle is to use the principle of electromagnetic induction, similar to a transformer, the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring the energy from the transmission end to the receiving end. The conversion efficiency is high, the cost is cheap, but the transmission distance is short and easy to bearThe location affects the display.
Wireless charging system mainly adopts the principle of electromagnetic induction, energy coupling through the coil to achieve energy transfer. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
