    摘要: The present disclosure relates to an ultrasonic touch device and a method. The ultrasonic touch device is disposed at a periphery of a display area of an electronic equipment. The ultrasonic touch device includes an ultrasonic ranging module. The ultrasonic ranging module includes a plurality of ultrasonic ranging units detected. The ultrasonic touch device includes a first position determining unit configured to determine a distance between a touch object and the ultrasonic ranging module, and determine a position of the touch object in a first coordinate direction of the display area according to the distance. The ultrasonic touch device includes a second position determining unit configured to determine a position of the touch object in a second coordinate direction of the display area according to a position of an ultrasonic ranging unit that receives the reflected ultrasonic waves in the ultrasonic ranging module.
