Abstract: A lens module comprises a frame, a lens unit, and a driving module for driving the lens unit to move relative to the frame. The lens unit comprises a body made of plastic, at least one lens located in a center of the body, and an embedded member made of metal. The metal embedded member is embedded within a thinner rim portion of the lens unit by means of a plastic insert-molding process in such a manner that, at least one protrusion of the metal embedded member is exposed outside of the rim portion. When the lens unit moves relative to the frame, a location where the lens unit might touch the frame is one of the at least one protrusion, and therefore the structural strength, endure ability of impact and endure ability of friction at the rim portion of the lens unit are increased. In addition, the protrusion can also act as a positioning post or winding post for a coil of the driving module. Or, the coil can also be electrically connected to the protrusion such that the metal embedded member can transmit electric current for the coil.

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: A camera system including a telephoto lens module is provided. The telephoto lens module includes a first image sensor, a first assembly, and a second assembly. The first assembly includes a first driving mechanism and a reflecting member connected to the first driving mechanism. The first driving mechanism is configured to drive the reflecting member to rotate around a first axis and a second axis. The second assembly is disposed between the first assembly and the first image sensor, including a second driving mechanism and a first lens. The second driving mechanism is configured to drive the first lens to move along a third axis. The first, second, and third axes are not parallel to each other. When light enters the telephoto lens along the first axis, light is reflected by the reflecting member and through the first lens along the third axis to the first image sensor.

Abstract: A button mechanism is provided, including a housing, a fixing member fixed on the housing, a moving member movably disposed in the fixing member, a pressing member disposed on the moving member, and a driving module for moving the moving member relative to the fixing member. When the pressing member pushes the moving member to move from an initial position along a first direction to a first position, the driving member moves the moving member from the first position along the first direction to a second position. When the moving member is in the second position, the driving member moves the moving member along a second direction to impact the pressing member, wherein the first direction is opposite to the second direction.
