ACTUATOR AND CAMERA MODULE INCLUDING THE SAME |
| 摘要 |
An actuator may include a piezoelectric member extended to be elongated in an optical axis direction; and a magnetic body disposed on the piezoelectric member so as to decrease contact wear between the piezoelectric member and a lens barrel. According to exemplary embodiments of the present disclosure, driving reliability of the piezoelectric member maybe improved by decreasing contact wear due to the contact between the lens barrel and the piezoelectric member. |
