Abstract: Embodiments of this application provide a pairing method and a pairing system. The pairing system includes a stylus, a wireless keyboard, and an electronic device. The stylus includes a first coil, and the wireless keyboard includes a second coil. The method includes: In response to that the wireless keyboard charges the stylus through the second coil and the first coil, the stylus sends a pairing request to the wireless keyboard through the first coil and the second coil. The wireless keyboard sends the pairing request to the electronic device. The electronic device displays a pairing dialog box based on the pairing request, where the pairing dialog box is used to prompt a user to trigger the electronic device and the stylus to perform pairing.

Abstract: A stylus and an electronic device component are disclosed. The stylus includes a stylus rod and a detachable stylus tip at one end of the stylus rod, and further includes a first electrode, a second electrode, and a circuit board. The first electrode is disposed in the stylus tip. The second electrode is disposed on an inner wall of the stylus rod, or the second electrode is disposed on a fastener in the stylus rod, and the second electrode is electrically connected to the second circuit board. This increases a distance between the first electrode and the second electrode, and reduces coupling between the first electrode and the second electrode. The stylus in embodiments of this application resolves a problem that writing accuracy of the stylus is reduced because the two electrodes in the stylus are easily coupled.

Abstract: A control method, a stylus, and a touch system. When a stylus is in a working mode, based on status information of an Nth frame of an uplink signal, a target receiving channel is controlled to be turned on in a preset manner to receive an (N+1)th frame of the uplink signal sent by an electronic device based on the target receiving channel, where the target receiving channel includes a first receiving channel formed between a first electrode and a control module, and/or a second receiving channel formed between a second electrode and the control module. Therefore, when an uplink signal received by the second electrode is interfered with, an uplink signal can also be normally received to be successfully decoded within a periodicity in which the first electrode works alone.

Abstract: This application discloses a function mode switching method, an electronic device, and a system, which relate to the field of terminal technologies. The method includes: establishing, by a stylus and the electronic device, a wireless communication connection. The stylus may have a plurality of different function modes. The plurality of different functional modes may include a first mode and a second mode. The stylus may be switched between the first mode and the second mode. A stylus may send different function signals to the electronic device in response to a received input based on different function modes, so that the electronic device performs a corresponding function in response to the function signal.

Abstract: An electronic device includes a camera and a position detection component arranged in an accommodating cavity. The position detection component includes a circuit board, a bracket, a first magnet, and a Hall sensor. The camera of the electronic device is arranged on the bracket, and the camera can stretch out of or retract into the accommodating cavity constituted by a housing. The Hall sensor includes a first working surface and a second working surface which respectively extend in different directions. The Hall sensor senses a magnetic field of the first magnet through the first working surface and the second working surface and generates induction signals. The induction signals are used to determine a stretching-out position and a retracting position of the camera.
