Electromagnetic driving module and camera device using the same
First Claim
1. An lens driving module, comprising:
- a fixed member;
a movable member for holding a lens and movably connected to the fixed member, wherein the lens has a main axis; and
a first electromagnetic component for driving the movable member to move relative to the fixed member, wherein the fixed member comprises a bottom spaced apart from the movable member, and the bottom comprises;
a conductive layer fowled in the bottom and electrically connected to the first electromagnetic component;
a position sensor for detecting a movement of the movable member to the fixed member and electrically connected to the conductive layer; and
a terminal electrically connected to the conductive layer and exposed by and partially embedded in the bottom, wherein a recess is formed on a surface of the bottom, and the position sensor is disposed in the recess, wherein the recess comprises a recess surface facing the position sensor, an electrical connecting portion is disposed between the sensor and the recess surface, the sensor is electrically connected to the conductive layer through the electrical connecting portion, and at least a portion of the sensor overlaps the electrical connecting portion and the recess surface when viewed in a normal direction of the recess surface.

Abstract
A lens driving module is provided and includes a movable member for holding a lens, a fixed member movably connected to the movable member and includes a bottom spaced apart from the movable member, a first electromagnetic component, and an adhesive material disposed on the bottom. The bottom includes a conductive layer formed in the bottom and electrically connected to the first electromagnetic component, a position sensor electrically connected to the conductive layer, and a terminal electrically connected to the conductive layer and exposed by and partially embedded in the bottom, wherein a distance between an upper surface of the bottom and the movable member is less than a distance between the adhesive material and the movable member, a recess is formed on the upper surface, and the position sensor is disposed in the recess.
