a display positioned at least partially within the housing; and
a haptic engine positioned at least partially within the housing, the haptic engine comprising:
an enclosure defining an internal cavity;
a moveable mass positioned within the internal cavity and defining a contact portion and configured to move along an axis to provide haptic output; and
