Abstract

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. The coil is wound around the outer periphery of the lens holder. The lens holder has a fixed length in the up and down direction and has a flange part and a protrusion. The flange portion protrudes outward from the outer peripheral wall of the lens holder in the radial direction to position the height position below the coil wrapped around the outer periphery of the lens holder; the protruding portion protrudes outward from the outer peripheral wall of the lens holder in the radial direction. The protruding portion has an inclined surface that is inclined downward from the radially outer side to the radially inner side, and the innermost diameter of the inclined surface positions the upper height position of the coil. A lens driving device including the lens holder, a camera device including the lens driving device, and an electronic device including the camera device. The device provided by the invention can control the oscillation of the coil wound in the lens holder.

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, which is driven by a voice coil motor method (VCM method), is used in an electronic device equipped with an autofocus camera and a camera. The above-mentioned electronic equipment adjusts the position of the lens in the direction of the optical axis through the lens driving device, and performs operations such as focusing and zooming. [0003] The arrangement of the 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 gasket component, a coil, an iron yoke, a magnet, a set of two fixed components, and a conductive packaging component. [0004] The lens holder has a predetermined length in the up and down direction, and is stable when the lens...
