  • Patent number: 10816879
    Abstract: An assembling method is provided for assembling a camera module with a substrate and a lens module includes the following steps. In a step (A), a sensing chip is installed on a surface of the substrate. In a step (B), a fixture is assembled with the substrate, wherein plural inner walls of the fixture are arranged around at least a lateral edge of the substrate. In a step (C), a glue is coated on a periphery of the surface of the substrate, wherein a movable range of the glue is limited by the plural inner walls of the fixture. In a step (D), a lens holder of the lens module is installed on the surface of the substrate, so that the lens holder and the substrate are combined together through the glue. In a step (E), the fixture is separated from the substrate.

  • Publication number: 20180367719
    Abstract: The present invention relates to a camera module, including an induction wafer and a non-circular lens. The induction wafer has an induction area. The non-circular lens is located above the induction wafer and covers the induction area, so that an external light ray can pass through the non-circular lens to be projected to the induction area. The non-circular lens is formed by cutting off a part of a circular lens, so as to generate a small-sized camera module. Therefore, the camera module of the present invention can be accommodated in a narrow space of a portable electronic device.

  • Patent number: 9742972
    Abstract: A camera module includes a lens assembly, a power device with a first circuit board, a second circuit board and a welding element. The first circuit board is partially bent, and thus an electrical contact of the first circuit board is exposed to a lateral side of the power device. The second circuit board includes a conductive hole corresponding to the electrical contact. The conductive hole is exposed to a lateral side of the second circuit board. The welding element is installed on the lateral side of the power device and the lateral side of the second circuit board. The welding element is contacted with the electrical contact and the conductive hole, so that the first circuit board and the second circuit board are electrically connected with each other.

  • Publication number: 20100252700
    Abstract: A suction cup assembly includes a base, a suction cup, a guiding part and a rotary rod. The base has a first opening, a second opening and a top surface. The guiding part includes a first guiding post having a first inclined slot and a second guiding post having a second included slot. After the first and second guiding posts respectively penetrate through the first and second openings, the first inclined slot and the second included slot are partially exposed. The both terminals of the rotary rod are respectively inserted into the first and second included slots and supported on the top surface of the base. During rotation of the rotary rod, the both terminals of the rotary rod are moved from the lower ends to the upper ends of the first and second included slots, so that the guiding part is uplifted and the suction cup is subject deformation.

  • Patent number: 7720246
    Abstract: A headphone device includes a sound amplifying member, a connecting member and a fixing member. The sound amplifying member includes a first speaker and a second speaker for outputting a sound. The connecting member is interconnected between the first speaker and the second speaker and made of first flexible material. The connecting member is flexibly wound around the first speaker and the second speaker. The fixing member is coupled to the sound amplifying member for securing the connecting member thereon after the connecting member is wound around the first speaker and the second speaker.

  • Patent number: 6724171
    Abstract: A movable plug-head for a travel-type battery charger. A metallic n-shaped stationing clamp replaces the conventional plastic clamp and conductive metallic spring plates so that the number of components and thickness of the n-shaped stationing clamp are reduced. Ultimately, material and assembling cost as well as overall thickness of the charger are all reduced.
