The wireless charging box of the future AirPods can be charged whatever its orientation

A new Apple patent released by the US Patent and Trademark Office (USPTO) entitled "Rechargeable In-ear Case" offers an improved method of wireless charging with a multi-coil wireless charging mat that enables efficient charging regardless of the orientation of the receiving device (via Apple Insider).

The wireless charging mats of the current generation require precise alignment between the charging coils and the receiving device for the energy to be transferred. To remedy this problem, Apple offers its own wireless charging process using images of a possible future AirPods wireless charging box, as well as an AirPower charging pad equipped with multiple small overlapping coils.

The proposed method uses a pair of small charge coils in the AirPods case, occupying the lower left and right corners of the rear. In the same way, an AirPower type charging pad is shown with a total of 16 charging coils distributed in three rows.

"With the suggested double-coil charging system in the case, Apple suggests that aligning the case correctly or forming an angle on the entire surface of the tablet does not matter, because it would mean at least one of the two receiver coils. . would be in a position sufficiently-sufficient for a charge.

In positions where both coils are able to take a sufficient amount of power to recharge, still a switching system would disable the weaker of the two coils. "

As with all Apple patents, there is no guarantee that the technology will actually be introduced into a future product or service.
