Ultrasonic sensors are developed from the use of ultrasonic sensor characteristics. Ultrasound is a mechanical vibration frequency higher than the acoustic waves from the transducer excitation voltage wafer vibration occurs, and it has high frequency, wave length, the diffraction of small, especially good directivity, to be directed rays propagation characteristics. Ultrasound for liquids, solids penetration ability is high, particularly in the sun opaque solid, which penetrate the depth of tens of meters. Ultrasonic encounter impurities or sub-interface will produce significant reflex reflector formed into echo, hit moving objects can produce Doppler effect. Therefore, ultrasonic sensors are widely used in industrial, defense, biomedical and other aspects.
Buzzer is an integrated structure of electronic transducers, DC voltage supply, widely used in computers,
printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, timers and other
electronic products for sound devices . ; Buzzer piezo buzzer and consists of electromagnetic buzzer types.
