摘要： An actuator assembly (4001) includes a first part (4002), a second part (4004), a bearing arrangement (4003) and a drive arrangement (4005). The bearing arrangement (4003) includes first to fourth flexures (40151, 40152, 40153, 40154) arranged about a primary axis (4009) passing through the actuator assembly (4001). The bearing arrangement (4003) supports the second part (4004) on the first part (4002). The second part (4004) is tiltable about first and/or second axes (4011, 4012) which are not parallel and which are perpendicular to the primary axis (4009). The drive arrangement (4005) includes four lengths of shape memory alloy wire (40101, 40102, 40103, 40104). The four lengths of shape memory alloy wire (40101, 40102, 40103, 40104) are coupled to the second part (4004) and to the first part (4002). The bearing 15 arrangement (4003) is configured to convert lateral force(s) normal to the primary axis (4009) generated by the drive arrangement (4005) into tilting of the second part (4004) about the first and/or second axes (4011, 4012). Each of the first to fourth flexures (40151, 40152, 40153, 40154) has a first end (4016) connected to the first part (4002) and a second end (4017) connected to the second part (4004). Each of the first to fourth flexures (40151, 40152, 40153, 40154) includes a feature (1016) configured to increase a first compliance of that flexure (40151, 40152, 40153, 40154) to displacement of the respective second end (4017) towards the respective first end (4016). The first compliance is less than a second compliance of that flexure (40151, 40152, 40153, 40154) to 25 displacement of the respective second end (4017) parallel to the primary axis (4009).

摘要： A camera system may include one or more voice coil motor (VCM) actuators to implement focus, tilt and shift functions. The VCM actuators may include coils segmented into multiple coil segments having individually impedances lower than the impedance of the respective coil as a whole. The coil segments may be individually driven by respective currents at different points in time to interact with magnet(s) to produce motive forces along the same axis. Based on the winding configuration and driving mode of the coil segments, the motive forces may move a lens group relative to an image sensor in a direction substantially orthogonal to an image plane, tilt the lens group relative to the image sensor, or shift the image sensor relative to the lens group on the image plane.

摘要： The present disclosure provides an optical unit with shake correction function capable of preventing a thrust receiving member, which fixes a sphere, from falling off from the movable body in an optical axis direction. According to some embodiments of the present disclosure, a thrust receiving member to which a first sphere is fixed is held by a holding portion formed of the cutout recess provided in a fixed body. A bottom wall surface of the holding portion makes contact with a bent plate portion of the thrust receiving member from −Z direction side. Further, locked surface parts provided on a pair of side wall surfaces of a holding portion make contact, from +Z direction side, with a pair of locking plate portions protruding from a bent plate portion in circumferential direction in the thrust receiving member.
