Abstract

The invention provides a lens holder, a lens driving device, a camera device and an electronic device; the lens driving device is driven by a voice coil motor, coil winding in the upper and lower direction with a fixed length, and the flange parts and projections, the convex edge of the outer circumferential wall of the coil wrapped around the lens bracket protruding from the outer circumference of the lens, the inclined plane from the radial lateral direction to the radial inward tilt. A lens driving device includes a lens holder, a camera device including a lens drive device and an electronic device including a camera device. The device provided by the invention can control the unstable condition of coil in the lens bracket.

Description

Technical field [0001] The invention relates to a lens holder, a camera driving device with a lens holder, a camera device and electronic equipment. Background technique [0002] A conventional lens driving device is used in electronic equipment equipped with an autofocus camera and a camera, and the lens driving device is driven by a voice coil motor method (VCM method). The above-mentioned electronic equipment adjusts the lens position in the optical axis direction through the lens driving device, and performs operations such as focusing and zooming. [0003] The configuration scheme of a lens driving device driven by a voice coil motor is shown in Patent Document 1 (Patent Publication No. 2007-121695). The lens driving device is equipped with a lens holder, a spacer member, a coil, an iron yoke, a magnet, a set of two fixing members, and a conductive package member. [0004] The lens holder has a predetermined length in the up and down direction, and remains stable when the lens...
