An electronic device with ultrasonic touch is provided. The electronic device includes a display device, an ultrasonic transmission device, an ultrasonic reception device, a substrate, an ultrasonic controller, and a sensing circuit. The substrate is adjacent to the ultrasonic transmission device and the ultrasonic reception device. The ultrasonic controller generates a control signal. The ultrasonic transmission device generates an ultrasonic wave in a direction toward the substrate according to the control signal, and the ultrasonic reception device simultaneously receives the ultrasonic wave according to the control signal through the substrate and generates a sensing signal corresponding to the received ultrasonic wave. The sensing circuit determines a position whether a touch occurs according to the sensing signal to generate a touch signal.
