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.
