1, mobile phone space charging technology is to install the transmitter coil wireless charging hole on the wireless charging base, install the receiving coil on the back of the mobile phone, when the mobile phone is near the charging seat charging, the transmitter coil due to access to the wireless charging hole alternating current, will produce alternating magnetic field. Magnetic field Wireless charging hole 2, wireless space charging technology is a wireless charging technology that enables electronic devices to achieve wireless charging technology through electromagnetic induction, magnetic resonance and other principles without plugging wires. The principle is that the electromagnetic wave signal is emitted through the transmitter (charger), and then the electromagnetic wave is received by the receiving end (electronic device), and the received energy is converted to achieve charging. 3, the principle of electromagnetic resonance wireless charging technology and the resonance of soundThe principle is the same wireless charging hole : an energy sending device and an energy receiving device are adjusted to the same frequency, and the energy of each other can be exchanged when resonating, so that the coil in one device can transfer electric energy to the coil in another device at a distance to complete the charging. 4, there is an electromagnetic signal sent in the sending single coil, and the receiving single coil can receive the electromagnetic signal sent, and then the electromagnetic signal is converted into current, and the current enters the mobile phone, so as to achieve the effect of wireless charging. In simple terms, wireless chargers actually rely on electromagnetic wave energyWhat is the role of the small hole on the right of Lenovo computer wireless card? Security keyhole: Purchase a security cable lock that fits this keyhole and can be used to lock the computer to a fixed object to prevent the computer from being stolen. Hard drive or solid-state drive: Depending on the model, the computer may be equipped with a user-upgradable large-capacity hard drive to meet a variety of storage needs. Combined audio jack: To listen to sound from your computer, plug the headphones or headphones' 5mm 4-pole plug into the combined audio jack. Restore the hole. On Lenovo computers, a recovery hole is placed on the right side. whenWhen the system has a problem and needs to be restored, the computer is shut down and the card pin is inserted into the hole to restore the system. Lenovo Group is a global technology company founded in China with a presence in 180 markets. Small hole on the right side of Lenovo new air14 is to prevent computer theft. The keyhole is every laptop computer will have, located on both sides of the computer opening and closing accessories, the notebook keyhole plus the computer lock is mainly to prevent the role of computer theft, to people's property plus a guarantee method. Tablet does not respond if touched. Shut down did not respond, to put it bluntly crash!You can poke a small sewing needle into the hole, and the machine will go back to normal. The actual hole is a reset button, generally do not move it. If it does not return to normal, then the hands-on ability is strong and the power supply is broken, and it is not possible to drop the word, and find customer service is the best choice. ** Get a MagSafe charger ** : First, make sure you have a MagSafe charger for the iPhone 14, which has a magnetic adsorption design and can work with iPhone 14 tight fit. ** Connect the charger to a power supply ** : Connect the MagSafe charger to a power outlet or USB port on your computer using an appropriate charging head and cable. Make sure the charger is properly powered on. Perform the following steps to enable the magnetic absorption function of the Apple 12: Connect the mobile phone to the adapter to ensure that the device can be identified successfully. Open the "Settings" menu and enter the "General" option. Find the "Charging Interface" or "Wireless charging" function in "General". Open the "Magnetic Charging Function" option, you can use the magnetic mode to charge. The use of magnetic charging treasure is to suck the magnetic charging treasure on the back of the mobile phone to carry out wireless charging. When using the magnetic charging bank, ensure that the magnetic charging bank has sufficient power. If you use it for the first time or do not use it for a long time, you need to fully charge the magnetic charging bank by inserting the cable of the magnetic charging bank into the power adapter or USB port of the computer. The magnetic charging bank is attached to the charging port of a mobile phone or other device. ** Confirm device support ** : First, ensure that your Huawei devices (such as mobile phones and tablets) support the magnetic absorption function. This usually means there is a magnetic area on the back or side of the device, orMagnetic absorption is supported through a specific phone case. ** Prepare magnetic accessories ** : Prepare magnetic accessories, such as magnetic charger, magnetic charging bank, magnetic holder, etc. Make sure these accessories are compatible with your Huawei device.
