  • Patent number: 10601967
    Abstract: An electronic device includes a first device housing and a second device housing. Each can optionally define a linear recess. A hinge couples the first device housing to the second device housing. The first device housing is pivotable about the hinge relative to the second device housing. A flexible display is situated in the linear recess, where included, and spans the hinge. The hinge includes a cam, a first support plate pivotally coupled to a first side of the cam, and a second support plate pivotally coupled to a second side of the cam. The first support plate, the cam, and the second support plate bridge the linear recess of each device housing when the electronic device is in an axially displaced open position, but define boundaries within which the flexible display defines a service loop when the electronic device is in a closed position.

  • Publication number: 20200081499
    Abstract: A device includes a housing. The housing can define a duct having a central axis. A first loading surface can extend into the duct toward the central axis, while a second loading surface can extend into the duct toward the central axis. A first driver and a second driver can be situated within the duct along the central axis. The first driver can abut the second driver. A first spring biases the first driver away from the first loading surface, thereby causing the first driver to apply a first loading force to the second driver. A second spring applies a second loading force to the second driver, along a common direction with the first loading force, to bias the second driver away from the second loading surface, with the first spring and second spring operating in parallel on the second driver.
