INDUCTION MODULE COMMONLY USED FOR SHORT-RANGE WIRELESS COMMUNICATION AND WIRELESS CHARGING

摘要

PROBLEM TO BE SOLVED: To provide an induction module commonly used for short-range wireless communication and wireless charging.SOLUTION: An induction module commonly used for short-range wireless communication and wireless charging includes a flat plate-like first induction plate, and a flat planar first coil and second coil about which a wire is wound around and the center of which is a through hole. The first coil and second coil are both placed on the first induction plate, and the second coil is housed in the through hole at the center of the first coil and is concentric with the first coil. This integrates the induction modules with two types of different frequency signals and reduces the area of the induction coils.
