Abstract

The invention relates to a voice coil motor actuator, comprising a moving piece, a coil, a plurality of magnets, an upper elastic sheet and a shell. The coil is wound on the outer wall of the moving piece; the shell comprises a plurality of side plates; and the plurality of side plates are sequentially connected end to end. Each magnet is fixed on two inner surfaces of two adjacent side plates; and the moving piece and the coil can be movably arranged in the shell. The upper elastic sheet is arranged on the moving piece and held in the shell. The plurality of magnets are arranged at the periphery of the coil, so that the moving piece moves along the central axis direction of the moving piece under the interactions between the magnets and the coil when the coil is electrified. The invention further relates to a picture taking device comprising the voice coil motor actuator.

Description

technical field [0001] The invention relates to a voice coil motor actuator and an image pickup device with the voice coil motor actuator. Background technique [0002] A voice coil motor actuator generally includes a casing, a fixed barrel located in the casing, and a movable part movably installed in the fixed barrel. A coil is arranged on the periphery of the movable part, and a magnet is arranged on the fixed tube. In the case of energization, the VCM actuator drives the movable part to reciprocate through the interaction force between the magnet and the energized coil. However, the above-mentioned voice coil motor actuator has a complex structure and a large volume, which is not conducive to the miniaturization of the voice coil motor actuator and the improvement of assembly efficiency. Contents of the invention [0003] In view of this, it is necessary to provide a simple and compact voice coil motor actuator and an imaging device with the voice coil motor actuator...
