Abstract: A double helix actuator is disclosed that includes a double helix coil wound around a movable proof mass that is enclosed within a magnetic structure. The double helix coil and the magnetic structure are arranged relative to each other so that the magnetic field generated by the entirety of the double helix coil contributes to a linear force direction of the actuator. The double helix actuator produces a greater linear force density compared to traditional racetrack coil actuators, where only a portion of the coil contributes to the linear force. The double helix actuator also produces torque in addition to linear force which allows the double helix to provide unique haptic sensations in a variety of applications.

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: A haptic actuator may include first and second bodies movable along an arcuate path of travel. The haptic actuator may also include a biasing member coupled between the first and second bodies. At least one electrical coil may be configured to move the first and second bodies to produce a haptic effect.

Abstract: The disclosed embodiments of haptic locomotion use one or more actuators to: 1) determine the properties of contact surfaces to improve various applications that use haptic locomotion; 2) automatically improve power transfer efficiency during wireless charging or cellular or wireless signal reception; 3) increase device accessibility for visually or hearing impaired users; 4) improve speaker and microphone performance; 5) protect a free falling mobile device from impact damage by orienting the mobile device to a low-risk orientation during free fall, or by driving the mobile device away from a high-risk orientation during free fall; and 6) control asymmetric surface friction using a directional magnetic field provided by an actuator to improve haptic locomotion in a desired direction of travel.

Abstract: A haptic actuator may include a housing having opposing first and second ends and first and second coils carried by the housing adjacent respective first and second ends thereof. Each coil may have a respective passageway therethrough. The actuator may include a field member including first and second masses adjacent respective first and second ends of the housing, and a permanent magnet having first and second ends coupled to respective ones of the first and second masses. The actuator may also include first and second flexures mounting respective first and second masses to the respective first and second ends of the housing so that the field member is reciprocally movable within the passageways of the coils responsive to powering the coils and so that the ends of the permanent magnet are within respective passageways of the coils when the coils are unpowered.
