Lens driving unit and camera module comprising the same |
摘要 |
Provided are a lens driving unit that generates a precise linear motion in a spatially limited structure by using a bending vibration piezoelectric motor having a new structure, and a camera module comprising the lens driving unit. The lens driving unit includes: a lens carrier supporting a lens and comprising a guide axis exposed at least partially to the outside and extending in a direction substantially perpendicular to the lens; and a piezoelectric driving unit having a center portion contacting the guide axis according to a bending motion of a piezoelectric element and moving the lens carrier in a direction in which the guide axis extends.
