Camera device actuator

A camera device actuator, comprising:

• a fixed housing having an internal space;
• a lens carrier disposed to be movable in an optical axis direction in an internal space of the housing and accommodating a lens;
• a magnet disposed on a side surface of the lens carrier;
• a member to be detected disposed on the side surface of the lens carrier, connected to the magnet, and having a width in the optical axis direction that is less than a width of the magnet in the optical axis direction;
• a driving coil disposed spaced apart from and opposite to the magnet, on a panel disposed on the housing;
• and
• a sensing coil comprising a first sensing coil and a second sensing coil disposed on the panel, spaced apart from and opposite to the member to be detected, and arranged in-line with each other in the optical axis direction,
• wherein an intermediate point of the width of the member to be detected is positioned on a same plane, perpendicular to the optical axis together with intermediate points of the first sensing coil and the second sensing coil, in a non-driving state of the camera device actuator.

A camera device actuator, comprising:

• a magnet disposed on a lens carrier and configured to move in an optical axis direction within a fixed housing;
• a detectable member disposed adjacent to the magnet on the lens carrier and having a width in the optical axis direction that is less than a width of the magnet in the optical axis direction;
• a driving coil facing and spaced apart from the magnet, and disposed on a panel disposed on the housing;
• and
• a sensing coil facing and spaced apart from the magnet, and disposed on the panel, wherein the sensing coil comprises a first sensing coil and a second sensing coil spaced apart from the first sensing coil in the optical axis direction.
