Abstract: This application provides a signal transmission method and a related device. According to the signal transmission method, when two contact points on an electronic device are respectively in contact with two contact points on a keyboard, the electronic device may transmit a power signal and a GND signal to the keyboard through the contact points that are in contact with each other, that is, the electronic device may supply power to the keyboard. In addition, when a user presses a key on the keyboard to perform input, the keyboard may transmit key position information to the electronic device through a contact point that is in contact with the electronic device. In this signal transmission method, no Bluetooth chip needs to be built into the electronic device and the keyboard, reducing device costs.

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.
