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.

Description

technical field [0001] The present invention relates generally to assemblies and / or systems that provide tactile feedback to users, and more particularly to touch screens and touch surfaces that provide tactile feedback to users. Background technique [0002] A new generation of consumer devices increasingly relies on touchscreen inputs such as virtual buttons and sliders displayed on the screen as an alternative to physical input. Users can interact with these devices almost exclusively by touching and / or otherwise manipulating on-screen virtual buttons, sliders, scroll bars, etc. with one or more fingers. On-screen graphical displays provide visual feedback in response to these manipulations. In some more recent touch screen devices, when the user's finger interacts with a virtual object on the touch screen, force feedback or tactile feedback can also be provided to the user, generally collectively referred to as tactile feedback. This is usually accomplished by moving o...
