- Aug 15, 2018-

According to Patently Apple, the US Trademark Patent Office passed 52 new patents earlier, including a unique inductive charging method, which used the coils used for microphones in mobile devices for wireless inductive charging.

Among them, Apple's patent for wireless charging can achieve the effect of wireless charging through sound waves and touch. The report considers this to be an interesting invention. In addition to being used as sound wave transmission, the coils in the device can also have the function of transmitting or receiving wireless charging. It is equivalent to developing multiple uses on a single device.
