    What’s ultrasonic transducer
    A transducer (probe) is a device that converts physical energy into and out. An ultrasonic probe converts electrical energy into acoustic energy and converts acoustic energy into electrical energy. The energy conversion is realized. Therefore, the ultrasonic probe is also called an ultrasonic transd
