    Abstract: This application discloses a wireless charging system, and relates to the field of terminal technologies. The wireless charging system includes a tablet computer, a wireless keyboard, and the electronic stylus. The wireless keyboard includes a keyboard body, a support, and a connection portion. The connection portion includes an accommodation cavity provided with an opening at one end. A first sending apparatus is disposed in the tablet computer. A first receiving apparatus is disposed in the keyboard body. A second sending apparatus is disposed in the accommodation cavity. The first receiving apparatus receives an alternating current signal sent by the first sending apparatus, and then directly transmits the alternating current signal to the second sending apparatus. The second sending apparatus is configured to wirelessly charge the electronic stylus accommodated in the accommodation cavity.

    Abstract: The present disclosure provides an accessory detection system that includes an electronic device and a to-be-attached accessory. The electronic device includes a first attachment component and a magnetic field detection device. The to-be-attached accessory includes a second attachment component, a first magnet, and a second magnet. The second attachment component is configured to be attached to the first attachment component, so that the to-be-attached accessory is fixed to the electronic device through attachment in a first orientation or a second orientation. The first magnet and the second magnet are configured to trigger the magnetic field detection device to output first indication information when the to-be-attached accessory is fixed to the electronic device through attachment, and the first indication information is used to indicate that the to-be-attached accessory is fixed in position through attachment.
