Abstract
Devices disclosed herein include a housing component, a touch screen, a haptic actuator for moving the touch screen relative to the housing component, and at least one dual stiffness suspension system that couples the touch screen and housing component together such that the touch screen is movable relative to the housing component. The dual stiffness suspension system has a first element of a first stiffness and a second element of a second stiffness which is stiffer than the first stiffness. The dual stiffness suspension system is configured to limit movement between the touch screen and the housing component in a first direction due to the first element of the dual stiffness suspension system while also being configured to allow movement of the touch screen relative to the housing component in a second opposing direction due to the second element of the dual stiffness suspension system.
