  • Patent number: 8351138
    Abstract: A lens displacement device includes a flexible piece, a fixed element and a mobile element. The flexible piece has a support, a flexible part and an oscillation absorber. The flexible part connects to the support and at least one gap exists between the flexible part and the support. The oscillation absorber is installed in the gap between the flexible part and the support. Moreover, the fixed element couples to the support of the flexible piece, and the mobile element couples to the flexible part of the flexible piece. Furthermore, the flexible part of the flexible piece is deformed in shape for providing a restoration force with the mobile element. A manufacturing process of the flexible piece is also disclosed.

  • Patent number: 8139299
    Abstract: A lens activating device includes at least one elastic piece, at least one stationary piece and a movable piece. At least one elastic piece has at least four sheet portions and four sets of elastic portions. Each set of the elastic portions are serpentine and connected between two sheet portions in order to make the at least one elastic piece form a closed ring. The stationary piece is connected to two sheet portions, and the movable portion is connected to the other two sheet portions. The elastic force generated by the four sets of elastic portions exerts a restoring force on the movable piece. Via this arrangement, the slight rotation of the movable piece within the lens activating device can be reduced. Further, the problem that the elastic piece may scrape the neighboring elements can be prevented.

  • Patent number: 7760453
    Abstract: The present invention provides a lens displacement device, applicable for moving micro image-capturing module lens, wherein the lens displacement device comprises: a lens slide base, a first hollow magnet, a hollow magnetic conducting plate, a second hollow magnet and a hollow coil. A first magnetic pole side of the hollow magnetic conducting plate is magnetically connected to the first hollow magnet, and a second magnetic pole side of the hollow magnetic conducting plate is magnetically connected to the second hollow magnet, which combined to form a magnetically connected assembly. The hollow coil is placed at the outer or inner perimeter of the magnetically connected assembly, and the hollow coil surrounds the magnetically connected assembly and they have a gap in-between them to allow for sliding. Herein the lens slide base rigidly connects the first hollow magnet of the magnetically connected assembly or the hollow coil.

  • Patent number: 7656074
    Abstract: A voice coil motor device for positioning is disclosed. The voice coil motor device for positioning includes a fixed element, a moving element and a connector. The moving element is movably disposed on the fixed element. One end of the connector is connected with the fixed element and the other end of the connector is connected with the moving element. A piezoelectric element is disposed on the connector or deposed between the moving element and the fixed element. The piezoelectric element can be deformed with the movement of the moving element to generate a displacement signal of a moving element. The positioning of the voice coil motor can be achieved precisely basing on the judgment on the displacement signal of the moving element generated with the movement of the moving element by the piezoelectric element.

  • Patent number: 7489459
    Abstract: A lens actuating apparatus includes a fixed part, a moving part and at least one flexible part. The moving part is movably located on the fixed part. The flexible part has four contacting portions that form a hollow enclosed body. Two contacting portions that are located at the diagonal direction fasten the fixing part, and the other two contacting portions that are located at another diagonal direction contact the moving part. When the moving part has a movement related to the fixed part, the contacting portions of the flexible part contacted the moving part move far away from the fixed part. Thereby, the moved contacting portions exert a flexible recovery force to the moving part. The flexible part can be fully utilized in a limited space and does not affect the allocation of the other elements.
