  • Patent number: 11977419
    Abstract: An electronic device is disclosed, including: a first housing, a second housing, a folding housing that pivotably connects the first housing and second housing, a flexible display spanning the first, second and folding housings, a printed circuit board (PCB), a first camera module at least partly visible through a surface of the second housing, a first magnet disposed in the first housing, a second magnet disposed in the second housing, and a hall sensor disposed on the PCB, the hall sensor configured to detect magnetic flux caused by motion of the first and/or second magnet in folding and unfolding of the electronic device so as facilitate determination of a configuration state of the electronic device.
    Type: Grant

  • Patent number: 11221676
    Abstract: A foldable electronic device is provided, which includes a hinge structure, a first housing that is connected to the hinge structure, a second housing that is connected to the hinge, a first vibration element disposed in the first housing, a first motion sensor disposed adjacent to the first vibration element, a second motion sensor disposed in the second housing, a processor, and a memory. The memory stores instructions that, when executed, cause the processor to control vibration intensity of the first vibration element, based on a first value measured from the first motion sensor and a second value measured from the second motion sensor.
