Abstract: Disclosed are a rotary mechanism and an electronic device. The rotary mechanism includes a base, a first swing arm, a first connecting plate, and a first multistable flexible mechanism. Both the first swing arm and the first connecting plate are hinged to one side of the base. The first multistable flexible mechanism is disposed on the first connecting plate, and the first multistable flexible mechanism cooperates with the first swing arm to switch between a first stable state and a second stable state. In the unfolded state of the rotary mechanism, the first multistable flexible mechanism is in the first stable state, so as to lock the first swing arm at a first locking position of the first swing arm with respect to the first connecting plate. In the folded state of the rotary mechanism, the first multistable flexible mechanism is in the second stable state, so as to lock the first swing arm at a second locking position of the first swing arm with respect to the first connecting plate.

Abstract: Embodiments of this application disclose a focusing method and an electronic device, including: In response to a first operation, an electronic device starts photographing, and displays a first interface. The electronic device displays a Kth frame of preview image in the first interface at a first moment. The Kth frame of preview image is collected by the camera by using a face of a first target as a first focusing frame, and the face of the first target meets a preset facial recognition condition in the Kth frame of preview image. The electronic device displays an Mth frame of preview image in the first interface at a second moment. The Mth frame of preview image is obtained by the camera by focusing on the first focusing frame, the face of the first target does not meet the preset facial recognition condition in the Mth frame of preview image.

Abstract: A method includes: displaying a user interface on a first screen, displaying at least one frame of continuous image of the dynamic wallpaper on the first screen, switching to a second screen for displaying the user interface, and displaying at least one frame of continuous image of the dynamic wallpaper on the second screen. Because a first frame of image displayed on the second screen is a last frame of image displayed on the first screen or a frame after a last frame of image displayed on the first screen, the at least one frame of continuous image of the dynamic wallpaper displayed on the first screen is continuous with the at least one frame of continuous image of the dynamic wallpaper displayed on the second screen.

Abstract: A system for detecting proper positioning of an accessory, including an electronic device and an accessory. The electronic device includes a first attachment component, a magnetometer, and a processor. The accessory includes a second attachment component. The second attachment component is configured to be attached to the first attachment component, so that the accessory is fixed through attachment to the electronic device in a first orientation or a second orientation. The magnetometer is further configured to be triggered by a combined magnetic field of the first attachment component and the second attachment component to output the magnetic field intensity information when the accessory is fixed through attachment to the electronic device in the first orientation or the second orientation. The processor indicates whether the accessory is fixed in position based on the magnetic field intensity information.

Abstract: Embodiments of this application provide a voice signal output method and an electronic device. The method includes: generating a first voice signal as an interfering signal based on a downlink voice signal; generating a second voice signal by performing delay processing on the downlink voice signal, where the second voice signal has a same delay as the first voice signal; and at a same output time, outputting the second voice signal using a first sound production assembly close to a human ear, and outputting the first voice signal using a second sound production assembly far from the human ear. This masks the downlink voice signal with the interfering signal, preventing others from clearly hearing the call content of the user and protecting user privacy.
