| 摘要 |
A piezoelectric-driving optical lens is disclosed, which comprises: a lens, having a barrel with a friction ring annularly mounted on the outer wall of the barrel as the outer diameter of the friction ring is larger than that of the barrel; a plurality of piezoelectric stators, arranged surrounding the lens and abutted against the friction ring, for providing a rotation driving force to the lens for focusing or zooming function; and a seat, for receiving the lens and the plural piezoelectric stators; wherein, the plural piezoelectric stators can actuate simultaneously to output a maximum driving torque.
