Lens driving device

Abstract

An lens holding device is disclosed. The lens holding device includes a stationary magnetic field generator having a housing and at least one magnet fixed on the housing, the housing having a receiving chamber; at least one elastic member attached to the stationary magnetic field generator; a movable magnetic field generator suspended in the receiving chamber by the elastic member and separated from the stationary magnetic field, the movable magnetic field generator having a lens holding device received in the housing for receiving at least a lens and a coil attached on the lens holding device and facing the magnet, the lens holding device having a lens barrel and a coil holder directly extending from the lens barrel for holding the coil. Wherein the lens barrel and the coil holder are integrated with each other, in which the pre-wind coil is then subsequently attached. This overcomes the issue of the coil deforming the lens barrel in the winding process.
