Ultrasonic Transducer Design Principle. Ultrasonic transducers can be divided into transmitters, receivers and transceivers by functions, as shown in Figure 2. For the example of a transducer operating at 40 kHz, the resonant frequency (fr) of the transmitters are designed at a frequency close to the operating frequency of the applied ...

Ultrasonic Transducer Working Principle. When an electrical signal is applied to this transducer, it vibrates around the specific frequency range and generates a sound wave. These sound waves travel and whenever any obstacle comes, these sound waves will reflect the transducer inform of echo. And at the end of the transducer, this echo converts ...

Thus the ultrasonic source creates a beam of ultrasound which acts as a virtual array of sound sources. Ultrasonic sound waves in the air are usually generated by piezoelectric or electrostatic transducers. The mechanical construction of the piezoelectric ceramic transducer that is used in the Acouspade directional speaker is shown below.
