摘要： Radial transducers are provided for acoustic touch sensors. Different radial transducer arrangements may allow for locating multiple simultaneous touches without ambiguity, in some embodiments without a bezel. Instead of transmitting acoustic waves along a line to be reflected at multiple points, surface acoustic waves are transmitted in a radial wave pattern. Surface acoustic waves are transmitted along different angles spread out over at least part of the touch region. Various techniques may be used to generate the radial wave pattern, such as a convex wedge of a wedge transducer, interference patterns, a curved piezoelectric element, a curved reflector, a curved edge of the substrate, a curved grating, or one or more lenses. These devices for controlling the spread of the surface acoustic waves may alternatively be used for control of the surface acoustic rays for transmission along a single line or just along two lines (e.g., X and Y axes).

摘要： Acoustic touch apparatus comprising a substrate having first and second surfaces capable of propagating surface acoustic waves, the second surface comprising a touch region and the first and second surfaces coupled via a rounded connecting surface; at least one acoustic wave transducer on the first surface; and at least one reflective array on the first surface. The transducer is capable of transmitting or receiving waves to and from the reflective array. The substrate and reflective array can acoustically couple waves between the first and second surfaces. The substrate has a border region on the first surface adapted to hide the transducer and reflective array and preclude distortion of waves propagating over a window in the border region. The border region may have a borderlayer except at the window and a corrective lens is used proximate the window, or the border region comprises discolored glass except at the window.
