Abstract
Methods of manufacturing a haptic device having a compliant suspension element. Segments of piezo material are coupled to at least one surface of at least one compliant suspension element, and the at least one suspension element is coupled to a touch screen component. The at least one suspension element is also coupled to a housing component. The segments of piezo material are configured to produce a force that moves the touch screen component relative to the housing component and thereby provide a haptic effect to a user of the touch screen component. In reaction to the force produced by the segments of piezo material, the at least one suspension element is configured to allow movement of the touch screen component relative to the housing component in a first direction and to limit movement between the touch screen component and the housing component in at least a second direction.
