The ultrasonic receiving unit generates low-frequency electrical signals when the acoustic touch device is touched by an external object or affected by acoustic noise. The low frequency electrical signals cause variation in the output electrical signals of the ultrasonic receiving unit. The controller is configured to power on or power off the ultrasonic transmitting unit according to such variation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Acoustic touch device and touch judging method","description":"An acoustic touch device able to distinguish between user finger touches and other noise-making events includes ultrasonic transmitting and receiving units, and a controller.
