Abstract
The present disclosure provides a signal intensity regulating circuit, an infrared touch device, and an electronic equipment. The signal intensity regulating circuit includes a signal acquiring circuit, a controller and a signal regulating circuit; a first signal end of the switch element is connected to the signal output end of the signal acquiring circuit to form a signal voltage-dividing node connected to the signal input end of the controller; the controller outputs a corresponding regulation signal to the controlled end of the switch element based on the touch sampling signal received at the current moment, the switch element receives regulation signals of different intensities to generate a corresponding on-resistance, the signal voltage-dividing node forms a touch sampling signal at the next moment under the voltage-dividing action of the output impedance of the signal acquiring circuit and the on-resistance, and transmits it to the signal input end of the controller.
