The present invention is applicable to the technical field of optical anti-shake devices, and provides an anti-magnetic interference optical anti-shake voice coil motor and a manufacturing method thereof. coil. The magnet is fixed on the inner wall of the casing, the coil is installed on the outer wall of the lens carrier, and the coil is arranged opposite to the magnet. The energized shrapnel is mechanically fixedly connected to the bottom of the lens carrier and the housing. The energized shrapnel is provided with at least three conductive paths, each conductive path corresponds to each coil, and has separate and adjacent input ends and a common end. Each coil The first wire end and the second wire end are respectively electrically connected to the corresponding input end and the common end. The invention is easy to manufacture, high in production efficiency, improves the focusing linearity of the voice coil motor, and enhances the accuracy and speed of automatic focusing; the magnet is located in a fixed structure, and the voice coil motor is not easily affected by an external magnetic field during operation.
Description
technical field [0001] The invention belongs to the technical field of optical anti-shake devices, in particular to an anti-magnetic interference optical anti-shake voice coil motor and a manufacturing method thereof. Background technique [0002] Today's miniature optical image stabilization voice coil motor technology has been widely used in high-end mobile phones, which can effectively reduce the chance of blurry photos taken in low-light environments, and reduce the disturbing shake in videos. However, compared with general auto-focus motors, anti-shake voice coil motors are more complex in design, lower in production yield and efficiency, and higher in cost. Therefore, described technology has not yet been popularized to mid-end and low-end mobile phones, and most mobile phone users still fail to enjoy the benefits brought by this technology. [0003] At present, miniature optical anti-shake voice coil motors can be divided into three categories, and their names and an...
