Abstract: A haptic actuator may include a spool having an opening therein and at least one coil wound on the spool. The haptic actuator may also include a tubular shaft bearing within the opening and a shaft slidable within the tubular shaft bearing. The haptic actuator may further include a field member coupled to the shaft and that includes a frame and at least one permanent magnet carried by the frame and surrounding the at least one coil.

Abstract: A haptic actuator may include a base, a field member coupled to the base and that may include spaced apart permanent magnets. The haptic actuator may also include a coil having a loop shape defining a slotted opening therein, and a spring member suspending the coil so that the field member is within the slotted opening and permitting relative movement of the field member and the coil.

Abstract: An electronic device may include a device housing and a haptic actuator carried by the device housing and that includes a haptic actuator housing and a field member movable within the haptic actuator housing. The electronic device may also include a motion sensor carried by the device housing to sense motion of the field member, an audio sensor carried by the device housing to sense audio noise from the haptic actuator, and a controller coupled to the haptic actuator, the motion sensor, and the audio sensor. The controller may be configured to drive the haptic actuator based upon sensed motion of the field member and audio noise from the haptic actuator.
