The invention provides a detection device for an ultrasonic transmitter and an ultrasonic receiver. The detection device for the ultrasonic transmitter comprises a processor, a sound card and a first ultrasonic receiver, wherein the processor is electrically connected with the sound card, and an output end of the first ultrasonic receiver is electrically connected with an input end of the sound card; and the first ultrasonic receiver receives ultrasonic waves transmitted by means of the ultrasonic transmitter of terminal equipment, the ultrasonic waves is subjected to signal conversion by means of the sound card, and then the processor judges whether the ultrasonic transmitter of the terminal equipment is qualified. The detection of the ultrasonic transmitter of the terminal equipment does not require manual operation, and the signal conversion is completely implemented by means of the detection device for the ultrasonic transmitter and the detection device for the ultrasonic receiver internally, thereby improving the detection efficiency.
Description
technical field [0001] The disclosure relates to the field of electronic technology, in particular to a detection device for an ultrasonic transmitter and receiver. Background technique [0002] With the development of electronic technology, the quality and experience of terminal equipment are becoming more and more important. Every terminal device needs to undergo rigorous testing and inspection before leaving the factory to ensure product quality and improve user experience. In the related technology, the terminal equipment has the functions of ultrasonic emission and reception, and the ultrasonic emission and reception can be used to control the screen to be turned off and on, and other functions can also be realized. However, due to the strong directivity and high frequency of ultrasonic broadcasting, ordinary audio test solutions cannot test the ultrasonic function of terminal equipment. Contents of the invention [0003] An embodiment of the present disclosure prov...
