Patent number: 9517531Abstract: A voice coil motor includes a coil support, a coil wound on the coil support, and two opposing lower elastic plates disposed on an upper part of the coil support. The outer edge of an upper flange of the coil support has at least two opposing protrusions which are arranged radially. The coil has a head end and a tail end which are respectively wound on the two protrusions. The two lower elastic plates are respectively connected with the coil wound on the two protrusions by welding. To prevent the head end from slanting, the lower elastic plates are mounted on the coil support through the operation of an automation apparatus to be soldered with the coil wound on the protrusions. The connection of the coil and the lower elastic plates is thus firm.Type: GrantFiled: April 10, 2014Date of Patent: December 13, 2016Assignee: XIAMEN XINHONGZHOU PRECISION TECHNOLOGY CO., LTD.Inventors: Wenchen Shen, Chengyang Wu, Shanmu Liu, Jianlong Zhang, Huangjie Lu

Patent number: 8648920Abstract: This invention provides an electromagnetically driven device applicable to a lens driving device with an anti-shake function by a simple structure that enables the movable member to swing around an axis thereof. A flat spring for swinging connects to a stationary frame body provided with a permanent magnet set and a coil set for swinging is mounted on an outer circumference of a movable frame body. When an axial direction of the movable frame body is designated as the Z axis, the coil set for swinging including a first through fourth coils arranged around the Z axis and spaced at uniform intervals with each winding around an axis perpendicular to the Z axis and opposite to the permanent magnet set respectively. The permanent magnet set includes a first through fourth magnets, wherein each magnet is arranged between two adjacent coils among the first through fourth coils.Type: GrantFiled: May 9, 2012Date of Patent: February 11, 2014Assignees: Micro Win Tech Inc., Largan Precision Co., Ltd., Xinhongzhou Precision Technology Co., LtdInventor: Kokichi Terajima
