Wireless power supply assembly and electronic device

Abstract

A wireless power supply assembly and an electronic device are disclosed. By providing a gap between the magnetic sheet and the coil, dense magnetic lines of force closely abutting the coil pass through the gap to avoid passing through the magnetic sheet, thereby reducing loss due to the magnetic sheet. At the meanwhile, it is also possible to further avoid significant changes in coil inductance parameters caused by horizontal offset between the coil and the magnetic sheet due to installation errors, reduce the sensitivity of the resonance compensation capacitance of the wireless power supply assembly to the position and further reduce the loss. The present disclosure can effectively reduce the loss of the wireless power supply system and improve wireless power transmission efficiency.
