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. part, the flange part protrudes outward from the outer peripheral wall of the lens holder in the radial direction, and locates the height position below the coil wrapped around the outer periphery of the lens holder; the protruding part protrudes outward from the outer peripheral wall of the lens holder in the radial direction, and the protruding part protrudes outward from the outer peripheral wall of the lens holder in the radial direction. The rim portion has a notch portion and a flange portion main portion other than the notch portion. The notch portion is provided by the flange portion at a position corresponding to the protrusion portion. Viewed from the optical axis direction, the flange portion main portion and the protrusion Parts do not overlap. 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

[0001] This application is a divisional application, the application number of the original application: 201510354517.5, the application date: June 23, 2015, Title of Invention: Lens Holder, Lens Driving Device, Camera Device and Electronic Equipment. technical field [0002] The invention relates to a lens holder, a camera driving device with a lens holder, a camera device and electronic equipment. Background technique [0003] 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. [0004] 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 equ...
