Abstract: A reluctance haptic engine for an electronic device includes a core, an attractor, and one or more flexible support members. The core and/or the attractor may be coupled to an input structure, such as a button cap, trackpad cover, touchscreen cover, or the like. In an unactuated configuration, flexible support members maintain a gap between the core and the attractor. An electrical current may be applied to one or more conduction loops of the core to actuate the reluctance haptic engine and provide a haptic output by moving the input structure. The electrical current may cause a magnetic flux that results in a reluctance force that pulls the attractor and the core together and causes the input structure to move (e.g., translate, rotate, oscillate, vibrate, or deform) to produce a haptic output.
