Document Type and Number:
WIPO Patent Application WO/2021/177638
Kind Code:
A1
Abstract:
An electronic device is disclosed, including a magnetic member, a position sensor configured to detect a change in a magnetic force of the magnetic member, a display, and a processor. The processor is configured to: when the magnetic member approaches an external electronic device, detect the change in the magnetic force of the magnetic member through the position sensor, and based on the detected change, display, on the display, a graphic indicating a direction in which the magnetic member is to be moved to align the electronic device with an external device for wireless charging. Another electronic device is disclosed, including an RF coil, a shielding sheet having at least two portions with two divergent magnetic permeabilities, and a processor configured to: control the RF coil to generate the wireless charging signal and transmit the wireless charging signal, wherein a magnetic member included in an external electronic device is changed in magnetic force values when approaching the at least two portions.
