A camera module is provided. The camera module includes a housing unit; a carrier, accommodated in the housing unit, and configured to move in an optical axis direction; a lens module, accommodated in the carrier, and in which one or more lenses are disposed; and a buffer member disposed on a side surface of the carrier, and configured to protrude in a direction perpendicular to the optical axis direction, and having a length in the optical axis direction, wherein the side surface of the carrier, on which the buffer member is disposed, has a length extending in the direction perpendicular to the optical axis direction.

Camera module

A camera module includes: a housing; a first dynamic component movably disposed in the housing in a direction of an optical axis; a second dynamic component including a lens and movably disposed on the first dynamic component in a direction orthogonal to the optical axis; a pocket configured in either one or both of the first dynamic component and the second dynamic component; a damping gel disposed in the pocket; and a damping pin extending from the first moving body or the second moving body, and at least partially embedded in the damping gel.

A camera module includes a housing, a lens module accommodated in the housing, a first optical image stabilization (OIS) driving unit configured to move the lens module, relative to the housing, in a first direction perpendicular to an optical axis direction, and a second OIS driving unit configured to move the lens module, relative to the housing, in a second direction perpendicular to the optical axis direction and intersecting the first direction, wherein the first OIS driving unit includes first voice coil motors disposed on both sides of the lens module in the first direction, and the second OIS driving unit includes second voice coil motors disposed on both sides of the lens module in the first direction.

There are provided a vibrator and an electronic device including the same. The vibrator includes: a housing having an internal space; an elastic member having both ends fixed to the housing so as to be disposed in the internal space in a state in which elastic deformation is possible; and a piezoelectric element mounted on one surface of the elastic member, wherein the piezoelectric element is fixed to the elastic member by soldering.
