METHOD OF TUNING A HAPTIC ACTUATOR AND RELATED APPARATUS |
摘要 |
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. |

1. A method of tuning a haptic actuator comprising 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, the haptic actuator operative as a resonator and having an initial quality (Q) factor, the method comprising:
determining the initial Q factor of the haptic actuator; determining a desired ferromagnetic mass for the housing to tune the initial Q factor to a desired Q factor; and changing the initial ferromagnetic mass of the housing to the desired ferromagnetic mass. |
