News editors obtained the following quote from the background information supplied by the inventors: "The present invention relates generally to an optical device, and more particularly to an optical lens module.
"As the improvement of technology image capture devices, such as digital camera, cell phone with camera, video game console and PDA, are very popular in ordinary life to record things.
"FIG. 1 shows a conventional optical lens module, including a barrel 60 and a lens group 62 mounted in the barrel 60 for reciprocation. The barrel 60 is provided with a coil 70, and a magnet 72 is provided on the lens group 62 so that the lens group 70 is moved by the magnet set 72 for focusing.
"In the conventional optical lens module, it may have a plurality of magnet sets, and each magnet is provided on a lens frame (such as focusing frame and zooming frame). At this time, the magnets will affect each other so that the optical lens module will have trouble in focusing or zooming. Therefore, the lens group only moves for focusing in the conventional optical lens module, and zooming is achieved by digital process. It is known that the digital zoom is a method of decreasing (narrowing) the apparent angle of view of a digital photographic or video image so that the image's quality is poor because of the limited pixels of the optical lens module.
"The electronic elements in the conventional image capture devices are connected by reflow. The reflow process is performed in a high temperature environment, usually is hundreds degrees, so that the magnets may lose its magnetism in high temperature. It may increase the ratio of defective in manufacture of the conventional optical lens module, and furthermore, it affects focusing."
As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventor's summary information for this patent application: "The primary objective of the present invention is to provide an optical lens module, which is not affected by high temperature and may drive multiple lens groups to move.
"According to the objective of the present invention, an optical lens module includes a barrel, at least a lens frame, and a driving device. The lens frame is mounted in the barrel for reciprocation and has at least a lens. The driving device has a fixed coil and a movable coil. The fixed coil is provided on the barrel, and the movable coil provided on the lens frame. Therefore, the lens frame is moved by the fixed coil while power is supplied to the fixed coil and the movable coil.
"In an embodiment, the driving device further includes a telescoping wire connected to the movable coil.
"In an embodiment, the driving device further includes a flexible member; and the flexible member urges the lens frame to return the lens frame when the lens frame is moved.
"In an embodiment, the flexible member is conductive; and the power is supplied to the movable coil through the flexible.
"In an embodiment, the movable coil is repelled by the fixed coil when power is supplied to the fixed coil and the movable coil.
"In an embodiment, the optical lens module has two or more lens frames, and each lens frame is provided with a movable coil. Therefore, the lens frames are respectively moved by the fixed coil while power is supplied to the coils.
"Therefore, high temperature will not make the coils losing magnetism, and the concept of the present invention may move multiple lens frames.
