Abstract: A portable electronic device may include an enclosure defining an interior cavity and having a front cover, and a haptic engine positioned in the interior cavity. The haptic engine may include a first body component defining a first side of the haptic engine and including a first spring flexure and a first end element molded over a portion of the first spring flexure, a second body component defining a second side of the haptic engine opposite the first side and including a second spring flexure and a second end element molded over a portion of the second spring flexure, a movable mass component coupled to the first spring flexure and the second spring flexure, and a coil configured to induce a linear movement of the movable mass component in response to the actuation signal thereby producing a haptic output.
