Abstract

An embodiment comprises: a housing comprising a first corner part and a second corner part opposite to the first corner part; a bobbin disposed in the housing; a magnet comprising a first magnet disposed in the first corner part of the housing and a second magnet disposed in the second corner part of the housing; a coil disposed on the bobbin and opposite to the magnet; a circuit board disposed on one surface of the housing and including a position sensor; and a sensing magnet disposed in the bobbin and opposite to the position sensor, wherein a protrusion part is formed to protrude from one surface of the bobbin, opposite to one surface of the housing, toward the one surface of the housing, and the sensing magnet is at least partially placed within the protrusion part of the bobbin.

Description

technical field [0001] Embodiments relate to a lens driving device and a lens module and an optical device respectively including the lens driving device. Background technique [0002] It is difficult to apply the technology of a voice coil motor (VCM) used in an existing general-purpose camera module to an ultra-small, low-power camera module, and thus research related thereto has been actively conducted. [0003] Demand for and production of electronic products such as camera-equipped smartphones and mobile phones have increased. Cameras for mobile phones are trending towards higher resolution and miniaturization. Accordingly, actuators have also been miniaturized, increased in diameter, and multifunctionalized. In order to realize a high-resolution camera for a mobile phone, it is necessary to improve the performance of the camera of the mobile phone and its additional functions, such as autofocus, hand-shake correction, and zoom. [0004] The camera may include: a sen...
