Specifically, in a state where the chip selection control input terminal CS and the increment control input terminal INC normally operate, when the up/down control input terminal U/D is at a high level, the resistance value or the voltage of the digital potentiometer 3 gradually increases, so that the driving voltage signal output by the digital potentiometer 3 decreases, that is, the voltage at the two ends of the sound prompt module 4 decreases, and the volume decreases; when the up/down control input terminal U/D is at a low level, the resistance or voltage of the digital potentiometer 3 gradually decreases, so that the driving voltage signal output by the digital potentiometer 3 increases, that is, the voltage at the two ends of the voice prompt module 4 increases, and the volume increases.
