摘要：A touch screen and a terminal are disclosed. The touch screen comprises: atouch panel, at least three pick-up devices, and a data calculation module, whereof: thetouch panel covers the pick-up devices and is used to provide a touch operation platform;the pick-up devices are used to detect effective sound signals produced by touchoperations, and to record detection time; and the data calculation module is used toascertain, on the basis of recorded detection times, the time differential of the effectivesound signal detected by each pick-up device, and to calculate the position of a touch-point by using the time differential and the path differential from a touch-point to eachpick-up device.
