  • Patent number: 11375120
    Abstract: A method is disclosed for capturing an image using an electronic device having a camera. The method comprises starting the camera in response to a first user input, displaying a first preview interface including a first preview image captured by a default lens of the camera, displaying a second preview interface in response to a second user input for increasing a zooming ratio in the first preview frame and when the zooming ratio in the first preview interface is greater than or equal to a threshold value, the second preview interface including a first frame and a second frame, and adjusting a zoom ratio of the second preview image in the second frame in response to a third user input for changing the zoom ratio.
    Type: Grant

  • Patent number: 11019432
    Abstract: A speaker includes a frame, a magnet, a diaphragm, a first coil, and a second coil assembly. The second coil assembly includes at least one second coil group, and each second coil group includes two second coils. The magnet and the diaphragm are mounted on the frame. The first coil and each second coil are coupled to the diaphragm. The first coil is configured to drive the diaphragm to vibrate. The second coil assembly is configured to, when the diaphragm vibrates and a difference between vibration displacements of two vibration regions in the diaphragm that are correspondingly coupled to two second coils in any second coil group exceeds a preset threshold, drive at least one of the two vibration regions to move to reduce the difference between the vibration displacements of the two vibration regions.
