    Abstract: An optical mechanism is provided, including an optical member, a reflecting element, a holder, and a housing. The optical member includes a first optical lens and a second optical lens. Light propagates into the optical mechanism in a first direction and is reflected by the reflecting element to propagate through the first and second optical lenses in a second direction. The holder supports the first and the second optical lenses, wherein the first and second optical lenses define an optical axis parallel to the second direction. The housing has a lower cover and a top cover, wherein the holder is accommodated in the housing. The first optical lens is closer to a light-entering end of the optical member than the second optical lens, and the first optical lens is larger than the second optical lens.

    Abstract: A driving mechanism for moving an optical element is provided, including a fixed part, a movable part, a driving assembly, and a flexible element. The movable part is connected to the optical element. The driving assembly drives the movable part to move relative to the fixed part. The flexible element is connected to the fixed part and the movable part. When the movable part moves relative to the fixed part, the flexible element deforms so that the position of the movable part relative to the fixed part can be detected.

    Abstract: The tri-axis close-loop feedback controlling module for electromagnetic lens driving device includes a 6-pin Hall element. Two pins of the Hall element are coupled to an auto-focus module for providing a current to drive the auto-focus module to conduct auto-focusing operations along the Z-axis; while other four pins of the Hall element are coupled to a control unit. The control unit detects the X-Y axial positions of the auto-focus module relative to an OIS module and generates a control signal which is then sent to the Hall element. Therefore, the Hall element not only can provide its own feedback controlling function according to the Z-axial position of lens, but also can drive the auto-focus module based on the control signal corresponding to the X-Y axial positions of the auto-focus module, so as to achieve the goal of tri-axis close-loop feedback controlling for the electromagnetic lens driving device.

    Abstract: An optical member driving mechanism is provided. The optical member driving mechanism includes a fixed portion, a movable portion, and a driving assembly. The fixed portion includes a housing, a frame, a circuit component, and a base. The housing includes a top wall and a plurality of sidewalls, forming a first containing space. The frame is disposed in the first containing space, and has a second containing space. The circuit component is disposed in the frame. The base is connected to the housing. The movable portion is movably connected to the fixed portion, and carries an optical member. The top wall is perpendicular to an optical axis. The sidewalls extend from the top wall along the optical axis. The driving assembly drives the movable portion to move relative to the fixed portion, is electrically connected to the circuit component and partially disposed in the second containing space.
