Abstract
The present disclosure relates to one or more intermediate layers located on a surface of a cover material of an acoustic touch screen. In some examples, the one or more layers can include one or more intermediate layers. The one or more intermediate layers can include a first layer including a plurality of features and a second layer located between the first layer and the cover material. In a touch condition, the touch object can apply a force to the top surface of the acoustic touch sensor. The applied force can create one or more local bends causing the plurality of features to move closer to the cover material and causing one or more surface discontinuities in the cover material. The acoustic waves can undergo reflections (e.g., causing the signal to be attenuated) due to the discontinuities located in the path of the wave propagation.
