This lens drive device is provided with: a first movable part; a second movable part; a first drive part; and a second drive part. The first drive part and the second drive part respectively have a first ultrasonic motor and a second ultrasonic motor. The first ultrasonic motor and the second ultrasonic motor are arranged on sides opposite to each other with respect an optical axis, and independently drive the first movable part and the second movable part in the optical axis direction.

A vibration-type actuator includes a vibrator, a contact body, a pressure member, a holding member, and a base. The vibrator has an elastic member and an electro-mechanical energy conversion element fixed to the elastic member. The contact body contacts the vibrator. The pressure member presses the contact body and the vibrator in a first direction. The holding member holds the vibrator and includes a support portion and at least one fitting hole portion extending in the first direction. The support portion supports the vibrator movably in the first direction. The base holds the holding member. The contact body moves relative to the vibrator in a second direction intersecting the first direction. The base includes at least one fitting protrusion portion extending in the first direction and fits in the at least one fitting hole portion.

Disclosed is a camera module. The camera module includes: a camera housing, a first carrier that is at least partially disposed in the camera housing and configured to move in a direction of an optical axis, a second carrier at least partially disposed in the first carrier and including a lens assembly, the second carrier configured to move together with the first carrier in the direction of the optical axis based on an auto focus function being performed and to move relative to the first carrier in at least one direction perpendicular to the optical axis based on an image stabilization function being performed, and a damping structure configured to provide damping to the movement of the second carrier based on the image stabilization function being performed. The damping structure includes a stopper disposed on an upper surface of the first carrier, a damping material located on a first surface of the second carrier at least partially facing the upper surface, and a protrusion extending from the stopper to be at least partially coupled to the damping material.

An embodiment of the present invention provides a camera module comprising: a fixed part; a moving part which moves relative to the fixed part in an optical axis direction, a first driving part which moves the moving part within a first maximum speed; and a second driving part which moves the moving part within a second maximum speed, wherein the first driving part and the second driving part move the moving part in the optical axis direction, and the second maximum speed is greater than the first maximum speed.

In some embodiments, a camera includes an optical package, a camera actuator for moving the optical package, a camera cover, and an impact absorption member to prevent contact between the camera cover and the lens carrier. In some embodiments, the camera actuator includes a lens carrier moveably mounted to a camera cover.

A lens moving apparatus includes a housing, a bobbin disposed in the housing, a first coil disposed on the bobbin, a magnet configured to move the bobbin in a first direction parallel to an optical axis by an electromagnetic interaction with the first coil, an elastic member coupled to the bobbin, and a second coil disposed on the housing. A first portion of the second coil is coupled to the housing. The second coil generates an induction voltage resulting from an inductive interaction with the first coil when the bobbin moves in the first direction.
