Abstract: Systems, methods, and computer-readable media provide multiple modes of haptic feedback for an electronic device using a single haptic actuator. Adjusting a parameter (e.g., frequency) of an actuator waveform generated by the single haptic actuator may affect how a mechanical coupling between the haptic actuator and a portion of the electronic device produces a device waveform at that device portion from the actuator waveform. A first mechanical coupling with a first response characteristic (e.g., stiffness or resonance frequency) may be provided between the haptic actuator and a first portion of the electronic device (e.g., a user input component of the electronic device), while a second mechanical coupling with a different second response characteristic may be provided between the haptic actuator and a second portion of the electronic device (e.g., the device housing of the electronic device) to selectively provide localized haptic feedback at the first portion of the electronic device.

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.

Abstract: According to some embodiments, a haptic feedback module for generating a haptic feedback event is described. The haptic feedback module includes an enclosure having walls that define a cavity. The enclosure is capable of carrying operational components within the cavity that include a frame that includes tungsten, a magnetic coil element that is capable of generating a magnetic field, a magnetic element that is carried within an aperture of the frame, linear-actuation end stops that are welded to a first end of the frame and a second end of the frame that opposes the first end, and springs that couple together the walls of the enclosure to the linear-actuation end stops.

Abstract: A module includes a permanent magnet biased electromagnetic haptic engine having a stator and a rotor; a constraint coupled to the stator and the rotor; and a force sensor at least partially attached to the permanent magnet biased electromagnetic haptic engine and configured to sense a force applied to the rotor. The constraint is configured to constrain closure of a gap between the rotor and the stator and bias the rotor toward a rest position in which the rotor is separated from the stator by the gap.
