    Abstract: A method is directed to tuning a haptic actuator that includes a housing having a ferromagnetic mass, a coil carried by the housing, and a field member movable within the housing responsive to the coil. The haptic actuator is operative as a resonator and having an initial quality (Q) factor. The method may include determining whether the initial Q factor is within a desired Q factor range, and when the initial Q factor is not within the desired Q factor range, performing ferromagnetic mass change iterations until an updated Q factor is within the desired Q factor range. Each ferromagnetic mass change iteration may include changing the ferromagnetic mass of the housing, determining the updated Q factor based upon changing the ferromagnetic mass of the housing, and determining whether the updated Q factor is within the desired Q factor range. Another embodiment changes the ferromagnetic mass of the field member.

    Abstract: An electronic device may include a haptic actuator that includes an actuator housing, coils carried within the actuator housing, and a field member movable within the actuator housing responsive to the coils. The haptic actuator may also include spaced apart Hall Effect sensors carried within the actuator housing between the coils and for sensing a temperature of the field member. The electronic device may also include a controller coupled to the haptic actuator and configured to determine a temperature of the field member based upon the spaced apart Hall Effect sensors and drive the haptic actuator based upon the temperature.

    Abstract: A haptic actuator may include a housing having a top and a bottom, and first and second coils 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 permanent magnet between the first and second coils, first and second ends, and a first mass between the first end and the permanent magnet, and a second mass between the second end and the permanent magnet. 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.
