    摘要: Provided is a lens barrel with which it is possible to suppress the influence of a disturbance magnetic field on a magnetic sensor. A coil that surrounds an outer periphery of a lens frame, magnetic force applying members that are disposed at a plurality of positions around the lens frame, and a magnetic sensor that detects an amount of movement of the lens frame are provided. In a plane orthogonal to an optical axis, the magnetic force applying members that are disposed on both sides adjacent to the magnetic sensor are disposed in postures in which a first angle (θ1, θ2) formed between a first straight line (L1) and a second straight line (L2) is smaller than 45°, the first straight line (L1) being a straight line passing through the magnetic sensor and the optical axis and the second straight line (L2) being a straight line orthogonal to surfaces of a first yoke and a second yoke of the magnetic force applying member that face each other.

    摘要: A lens driving apparatus includes a housing; a lens holding member positioned in the housing for holding a lens body, a coil, a detection magnet, and a balance magnet; first and second magnetic field generating members facing each other across the coil and the lens holding member; the detection magnet for detecting a position of the lens holding member; a magnetic detection member facing the detection magnet; the balance magnet facing the detection magnet across an optical axis of the lens body; and first and second leaf springs conducted to the ends of the coil, movably supporting the lens holding member in the optical axis direction. The detection magnet is disposed closer to the first magnetic field generating member than to the second magnetic field generating member, and the balance magnet is disposed closer to the second magnetic field generating member than to the first magnetic field generating member.

    摘要: An aspect of the present disclosure is drawn to an electronic switch module including: a housing having a chute; a plunger member moveably mounted within the chute so as to be able to move along a first axis with a first velocity; a magnet member disposed within the housing; a Hall sensor disposed within the housing; and a displacement mechanism disposed within the housing and operable to displace the magnet member along a second axis with a second velocity by a distance away from the Hall sensor, wherein the first velocity is greater than the second velocity, and wherein the Hall sensor is operable to output a signal associated with a first location of the plunger member along the first axis based on a second location of the magnet member along the second axis.

    摘要: Disclosed is a lens driving apparatus. The lens driving apparatus includes a base formed at a center thereof with a first opening; a housing coupled with the base and having a second opening corresponding to the first opening; a yoke installed on the base and including a horizontal plate having a third opening corresponding to the first opening and a vertical plate protruding upward from the horizontal plate; a bobbin movably installed in the yoke and coupled with a lens module; a coil fixedly disposed around the bobbin; a plurality of magnets provided at the vertical plate of the yoke to face the coil; and a spring installed on at least one of upper and lower portions of the yoke to return the bobbin, which has moved up due to interaction between the magnet and the coil, to its initial position.
