Charge the ear with a wireless charging coil
Ear charging wireless charging coil belongs to a kind of wireless charging coil, its small size, strong stability, fast charging speed and other characteristics are favored by the market, ear charging wireless charging coil is based on wireless charging technology designed coil, wireless charging from radio energy transmission technology, low-power wireless charging often uses electromagnetic induction type (such as the Qi way of charging mobile phones, However, ZTE's electric vehicle wireless charging method uses inductive mode), high-power wireless charging coil charging often adopts resonant mode (most electric vehicle charging uses this mode) by the power supply device (charger) to transmit energy to the electrical device, the device uses the received energy to charge the battery, and at the same time for its own operation. Since the energy is transmitted between the charger and the electrical device by a magnetic field, no wires are connected between the two, so the charger and the electrical device can be exposed without conducting contacts.
