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 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 may include two diverging arms joined together at proximal ends and having spaced distal ends operatively coupled between adjacent portions or the field member and the housing. The two diverging arms may each include a proximal segment having a reduced material medial portion relative to adjacent end portions, and a distal segment, being canted with respect to the proximal segment, and having a reduced material medial portion relative to adjacent end portions.
