Abstract
Various implementations disclosed herein include a surface mountable haptic actuator that includes a housing defining an interior chamber and a movable magnetic weight structure suspended within the interior chamber by a flexible member. The surface mountable haptic actuator further includes a stationary conductive coil positioned within the interior chamber proximate the movable magnetic weight structure and a plurality of conductive terminals extending through the housing and in electrical contact with the conductive coil.
Claims14
A haptic actuator comprising:
- a housing defining an interior chamber, wherein the housing includes an upper housing assembly comprising an upper housing plate;
- a movable magnetic weight structure suspended within the interior chamber by a flexible member;
- a stationary conductive coil positioned within the interior chamber proximate the movable magnetic weight structure, the flexible member mechanically attached to the upper housing plate and the movable magnetic weight structure mechanically attached to the upper housing plate by the flexible member, wherein the housing further comprises a lower housing assembly comprising a lower housing comprising an integrated yoke plate and the stationary conductive coil wound around the integrated yoke plate;
- and
- a plurality of conductive terminals extending through the housing and in electrical contact with the conductive coil.
