Abstract: A haptic actuator may include a housing having a top and a bottom, and first and second permanent magnets carried by the top and bottom, respectively, of the housing. The haptic actuator may also include a field member carried by the housing. The field member may include a coil between the first and second permanent magnets, first and second ends, and a first mass between the first end and the coil, and a second mass between the second end and the coil. A first shaft may slidably couple the first mass to the housing, and a second shaft may slidably couple the second mass to the housing. The haptic actuator may also include a first set of biasing members between the first end of the field member and the housing and a second set of biasing members between the second end of the field member and the housing.

Abstract: A method of tuning a haptic actuator that includes a housing having an initial ferromagnetic mass, at least one coil carried by the housing, and a field member movable within the housing responsive to the at least one coil, wherein the haptic actuator operative as a resonator and having an initial quality (Q) factor, may include measuring the initial Q factor of the haptic actuator. The method may include determining a desired ferromagnetic mass for the housing to tune the initial Q factor to a desired Q factor. The method may also include changing the initial ferromagnetic mass of the housing to the desired ferromagnetic mass. Another embodiment changes the ferromagnetic mass of the field member.
