13 inch touch screen ultrabook.A mechanical energy wave that propagates shallowly on the surface of a medium (such as a rigid material such as glass or metal). Through the wedge-shaped triangular base (strictly designed according to the wavelength of the surface wave), directional, small-angle surface acoustic wave energy emission can be achieved. Surface acoustic wave performance is stable, easy to analyze, and has very sharp frequency characteristics in the process of shear wave transmission. In recent years, it has developed rapidly in the direction of non-destructive testing, contrast imaging and dewave. The theoretical research on surface acoustic waves, semiconductor materials, acoustics Technology such as conductive materials and detection technology have been quite mature. The touch screen part of the surface acoustic wave touch screen can be a flat, spherical or cylindrical glass flat plate, which is installed in front of the CRT, LED, LCD or plasma display screen. The upper left corner and the lower right corner of the glass screen are respectively fixed with vertical and horizontal ultrasonic transmitting transducers, and the upper right corner is fixed with two corresponding ultrasonic receiving transducers. The four perimeters of the glass screen are engraved with very precise reflection stripes at an angle of 45 ?? from sparse to densely spaced.
