  I don’t know if you have noticed that at present, the wireless mobile phone charger function of the mobile phone must be placed on the designated charging board during the use process to realize the wireless charger function of the mobile phone. I don’t know if you have ever had such a question. Since it is a wireless charger, why do you have to put the phone on the charging tray of the phone? Why not like wifi, as long as it is within a certain range, it can be charged at any location?

What is the principle of mobile phone wireless charger(图1)

  Generally speaking, according to the current wireless charger mode and implementation principle of mobile phones, it generally comes down to three categories, magnetic resonance, electromagnetic induction, and radio waves. Now speaking, the most used is electromagnetic induction. Compared with the other two wireless charger methods, electromagnetic induction technology is more mature, and the charging efficiency is higher than other methods. Secondly, its implementation structure is simpler and more stable. So our mobile phones currently use this electromagnetic induction type.

  However, the current wireless mobile phone charger function of mobile phones is still not mature, charging is slow, and charging efficiency is low. Secondly, there are large shortcomings in the distance of the wireless charger. At present, the effective charging distance of the wireless charger of mobile phones is about 10mm. Within, this distance can be very short. And when our mobile phone is charging, it needs to be placed on the center of the charging board. If it is not in the center, it will directly affect the efficiency of the wireless charger.
