  • Patent number: 9891405
    Abstract: A camera module of an electronic device includes a lens unit with a first coil, a vibration unit with a second coil, and a magnetic unit. The vibration unit is positioned outside the lens unit and spaces a first certain distance with the lens unit. The magnetic unit is positioned outside the vibration unit and spaces a second distance with the vibration unit. When the first coil receives electrical signal, the first coil is actuated to move with the lens unit. When the second coil receives electrical signal, the second coil is actuated to move with the vibration unit with the vibration unit. Therefore, the magnetic blocks are cooperated with the lens assembly and the vibration block, to make an automatic focusing function and a vibration function being combined in the camera module.

  • Patent number: 9049776
    Abstract: A latching module for latching two housings together includes a rotary member, a compression spring, an elastic sheet, and a magnetic member. The rotary member is attached to one housing, and includes a first surface, a second surface opposite to the first surface, and a peripheral surface. The first surface defines a first receiving hole and a curved groove. The second surface defines a second receiving hole communicating with the first receiving hole. A latching projection extends from the peripheral surface. The compression spring is received in the second receiving hole. The elastic sheet is attached to the peripheral surface. The magnetic member is received in the curved groove. The magnetic member is attracted by another magnet to rotate the latching projection into a latch in another housing.

  • Publication number: 20140146452
    Abstract: A housing of electronic device includes a back shell defining an assembly hole, a main body, a fixing element comprising a head, and a connection element fixed to the back shell. The connection element defines a receiving hole for receiving the head of the fixing element and a through hole aligned with the assembly hole. The inner diameter of the assembly hole is smaller than an inner diameter of the receiving hole and the diameter of the head of the fixing element. The assembly hole may receive a shank of a screwdriver that threads the fixing element into the main body. An electronic device including the housing is also provided.
