交互式触摸屏广告。以右下角的x轴发射传感器为例:发送的发射换能器将电信号通过触摸屏控制器电缆成声波能量并将其传输到左边的表面,然后通过一套精密玻璃板下反射条纹反映了声波能量到一个向上的均匀表面传播。声波能量通过屏体表面，上方的反射条纹聚集成一条向右的线，传播到x轴接收换能器。接收换能器将返回的表面声波能量变成电信号。发射换能器发射窄脉冲后，声波能量通过不同路径到达接收换能器，最早到达的在最右边，最晚到达的在最左边，这些声波能量的早到和晚到叠加在一起。不难看出，波形信号是宽的。接收到的信号在x轴方向上收集所有通过不同路径返回的声波能量。它们在y轴上有相同的距离，但在x轴上，最远的比率是最近的那个走了最大x轴距离的两倍。因此，该波形信号的时间轴反映的是每个原始波形叠加前的位置，即X轴坐标。当发射信号和接收信号波形无接触时，接收到的信号波形与参考波形完全相同。 When a finger or other object capable of absorbing or blocking the sound wave energy touches the screen, the sound wave energy that the X axis travels upwards through the finger part is partially absorbed, reflecting that the waveform has an attenuation gap on the receiving waveform, that is, at a certain time position. The received waveform attenuates a gap corresponding to the signal blocked by the finger. To calculate the gap position, you must touch the coordinate controller to analyze the attenuation of the received signal and determine the X coordinate from the gap position. After that, the same process of the Y axis determines the Y coordinate of the touch point. In addition to the X and Y coordinates that general touch screens can respond to, the surface acoustic wave touch screen also responds to the third axis Z coordinate, which can sense the user's touch pressure value. The principle is calculated from the attenuation at the received signal attenuation. Once the three axes are determined, the controller passes them to the host.
