Abstract

Flexible suspension elements are disclosed for mounting electronic touch screens or touch surfaces. At least one flexible suspension element couples the touch screen and housing component together such that the touch screen component is movable relative to the housing component. Segments of piezoelectric material are coupled to opposing surfaces of the at least one suspension element for generating a force that moves the touch screen component relative to the housing component and thereby provides a tactile effect to a user of the touch screen component. In response to a force generated by the segment of piezoelectric material, at least one suspension element is configured to allow movement of the touch screen component relative to the housing component in a first direction, while also being configured to limit movement between the touch screen component and the housing component in at least a second direction. direction of movement.

Description

technical field [0001] The present invention relates generally to touch screens and other touch surfaces, and more particularly to touch screens and touch surfaces that provide tactile feedback to a user. Background technique [0002] New generations of consumer devices increasingly rely on touchscreen input, such as through virtual buttons and scroll bars displayed on the touchscreen instead of physical input. Users use these devices almost exclusively with one or more fingers by touching and / or otherwise manipulating virtual buttons, scroll bars, scroll wheels, etc. on the screen. In response to these operations, graphics are displayed on the screen to provide visual feedback. In more current touch screen devices, force feedback or haptic feedback (collectively referred to as haptic feedback) may also be provided to the user when the user touches a virtual control on the touch screen with a finger. This is typically accomplished by moving or vibrating the screen by a hap...
