If there is a chemical formula in this case, please reveal the best way to show the characteristics of the invention. ▪ Learning: (None) Invention: Technical Field of the Invention The present invention relates to a lens shift. The position mechanism is applied to an autofocus or zoom lens group, especially a coil and an electromagnet, and the electromagnetic force generated between the two is used to drive And controlling the lens by sliding displacement. [Prior Art] The digital camera with a digital camera, a mobile phone with a shooting function, and a hand-held electronic device such as a notebook computer 200935157 brain are currently equipped with a micro lens module with auto-focusing (AF) or zooming (zooming). A compact camera module (CCM), the lens module basically comprises: a housing formed by an upper cover and a bottom cover; a lens (lens) of the lens group (lensgroup) and a lens holder (lensholder), can be sleeved in the cavity and can slide back and forth in the direction of the central axis; and a lens displacement mechanism, or actuator ), which is mainly used to drive the lens to produce a shifting action on the central axis, thereby achieving the effect of autofocus or zoom.常见 The design of a common lens shifting mechanism is called a piezoelectric motor, which is formed by the principle of piezoelectric materials, such as US 7,212,358, US2003/0227560, JP2006-293083, JP2006- 101611, etc.; but the piezoelectric materials generally used cannot withstand the high temperature of reflow (ref 〇 w) operation, or the special piezoelectric materials that withstand high temperatures are quite expensive, which is not conducive to mass production. Or reduce manufacturing costs. Another type of voice coil motor (VCM) is formed by using a coil, a magnet, and an elastic member such as a spring or a spring, such as US 7,262,927, US 7,196,978. US7, 002, 879, US6, 961, 〇9〇, US6,687,062, US20070133110, JP2005037865, JP2005258355, W02007026830, etc., most of these conventional techniques use coils and permanent magnets, as shown in the figure. 1. If one or several permanent magnets 70 are arranged in a ring shape around the circumference or the periphery of the coil 31, the coil 31 is energized to generate a magnetic field, and can be connected with the magnetic field and the magnetic pole established by the one or several permanent magnets 70. Forms an upward or downward electromagnetic. The force drives the lens to move; however, the permanent magnet will demagnetize the magnet when reflowing at a high temperature (about 260 ΐ). Therefore, the conventional piezoelectric motor and the voice coil motor cannot be used in the assembly mode, and the mass production efficiency is limited to 4 200935157. Furthermore, there is a lens shifting mechanism using a shape memory alloy (SMA), which utilizes the characteristics of the heat shrinkage of the SMA as a driving source of the brake (aCfuat〇r), such as US 6,307,678B2, US 6,449,434B1, US2007058070, US2007047938, jp2〇〇5275270, JP2005195998, etc. However, the SMA heat shrinking action is slower, and it is easy to achieve instant autofocus or zoom effect. ..." For users who are still in need of quality, in the low-light environment, it is excellent in action and quality, and anti-shake.

Can increase the possibility of mass production. < 2 > The lens shifting mechanism 3 of the present invention can independently control each of the electromagnets in the electromagnet group 32 to have an anti-shake function. The above is only the preferred embodiment of the present invention, and is intended to be illustrative, and not restrictive, and it is understood by those skilled in the art that Many changes, modifications, and even equivalents may be made without departing from the scope of the invention.
