Abstract
A haptic actuator may include a housing, at least one coil carried by the housing, and a field member having opposing first and second sides. The haptic actuator may also include a respective at least one flexure bearing mounting each of the first and second sides of the field member to be reciprocally movable within the housing responsive to the at least one coil. Each flexure bearing may include at least one flexible member having a wishbone shape with two diverging arms joined together at proximal ends and having spaced distal ends operatively coupled between adjacent portions of the field member and the housing.
