A haptic actuator may include a housing having opposing first and second ends and first and second coils carried by the housing adjacent respective first and second ends thereof. Each coil may have a respective passageway therethrough. The actuator may include a field member including first and second masses adjacent respective first and second ends of the housing, and a permanent magnet having first and second ends coupled to respective ones of the first and second masses. The actuator may also include first and second flexures mounting respective first and second masses to the respective first and second ends of the housing so that the field member is reciprocally movable within the passageways of the coils responsive to powering the coils and so that the ends of the permanent magnet are within respective passageways of the coils when the coils are unpowered.

A rotary reciprocating drive actuator includes: a movable body including a shaft portion and a magnet fixed to the shaft portion; a fixing body including a core assembly, the core assembly including a core body and coils, the core body having magnetic poles, the core assembly being disposed such that the magnetic poles face an outer periphery of the magnet; and a pair of shaft supports configured to sandwich the core assembly in an extending direction of extension of the shaft portion and support the shaft portion at opposite sides of the core assembly such that the shaft portion is rotatable, in which a magnetic flux passing through the core body is generated by energization of the coils, causing reciprocating rotation of the movable body about an axis of the shaft portion by electromagnetic interaction between the magnetic flux and the magnet.
