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: A device includes a button, a base, a haptic engine coupled to the base, and a fastener fastening the button to the base and allowing movement of the button with respect to the base. The movement of the button with respect to the base enables, in part, a better alignment of the button with a device housing to which the base is attached. The haptic engine may include a core, an electric coil wound around a portion of the core, and an attraction plate separated from the core by a gap. The base may include a frame, a set of tabs extending from the core and fastened to the button to allow the movement of the button with respect to the base, and a set of flexures extending from the tabs and coupling the core to the frame. The attraction plate may also be coupled to the frame.
