    Abstract: A haptic actuator may include a housing, at least one permanent magnet carried by the housing, and a field member movable within the housing and comprising at least one coil cooperating with the at least one permanent magnet. The housing, at least one coil, and field member may define a resonant frequency. The haptic actuator may also include drive circuitry coupled to the at least one coil and being capable of generating first and second drive waveforms having respective different frequencies spaced about the resonant frequency to drive the field member at a beat frequency lower than the resonant frequency.

    Abstract: An electronic device may include a haptic actuator that may include a housing and a field member movable within the housing, and a driver capable of driving the haptic actuator and sensing at least one of a drive voltage and drive current for the haptic actuator. The electronic device may also include a closed-loop controller cooperating with the driver. The closed-loop controller may be capable of determining a calibration of the haptic actuator based upon at least one of the drive voltage and drive current, storing a reference pattern of movement for the field member, and driving the haptic actuator in a closed-loop configuration based upon the calibration of the haptic actuator and reference pattern of movement of the field member.

    CPC classification number: G08B6/00

    Abstract: A haptic actuator may include a housing, at least one coil carried by the housing, and a field member having opposing first and second sides. The haptic actuator may also include a respective flexure bearing mounting each of the first and second sides of the field member to be reciprocally movable within the housing responsive to the at least one coil. Each flexure bearing may include a first anchor member coupled to an adjacent portion of the housing, a second anchor member coupled to an adjacent side of the field member, and a first flexible arm coupling the first and second anchor members together and having at least one bend therein.

    Abstract: A haptic actuator may include a housing having a top and a bottom. At least one of the top and the bottom may have a shape defining an internal recess therein. The haptic actuator may include a coil carried within the internal recess, and a field member having opposing first and second sides and that includes at least one permanent magnet adjacent the coil. The haptic actuator may also include a respective flexure bearing mounting each of the first and second sides of the field member to be reciprocally movable within the housing responsive to the coil.

    Abstract: A haptic actuator may include a housing, at least one coil carried by the housing, and a field member having opposing first and second sides. The haptic actuator may also include a respective at least one flexure bearing mounting each of the first and second sides of the field member to be reciprocally movable within the housing responsive to the at least one coil. Each flexure bearing may include two diverging arms joined together at proximal ends and having spaced distal ends operatively coupled between adjacent portions of the field member and the housing. The two diverging arms may each have a reduced size medial portion relative to respective proximal and distal ends.

    Abstract: An electronic device may include a device housing, a touch display carried by the device housing and configured to sense a user input at a location thereon, and haptic actuators spaced apart within the device housing. The electronic device may also include a controller coupled to the touch display and the haptic actuators. The controller may be configured to cooperate with the touch display to determine a sensed location of the user input on the touch display, and drive the haptic actuators to focus a haptic sensation at the sensed location on the touch display.
