Abstract:
1. A touch input device, comprising: (a) a substrate having a first planar surface and a second planar surface; (b) an acoustic wave transducer for generating acoustic waves, the acoustic wave transducer coupled to the second planar surface such that generated acoustic waves are transmitted to the first planar surface; (c) planar wiring printed on the second planar surface; and (d) means for connecting the planar wiring to the acoustic wave transducer comprising a first electrode that couples a first portion of a first side of the transducer to a first portion of the planar wiring and a second electrode that couples a second portion of the first side of the transducer to a second portion of the planar wiring, the second electrode extending from the first side of the transducer to a second side of the transducer opposed to the first portion of the first side of the transducer.
