Abstract
Embodiments of this application provide an electronic device component. A first charging coil and a second charging coil are respectively disposed in a wireless keyboard and a stylus. At least one of the first charging coil and the second charging coil is a circle coil, and the circle coil is disposed around circumference of an accommodating portion or the stylus. The stylus can be charged when the stylus is blindly inserted into the accommodating portion, to resolve a prior-art problem that a user cannot quickly charge the stylus because the charging coils need to be aligned for a plurality of times when the stylus is charged.
