Ultrasonic transducer is an energy converter device that converts alternating electrical signals into acoustic signals within the ultrasonic frequency range or converts acoustic signals from the external sound field into electrical signals. It is a key component in ultrasonic technology, and its performance directly affects the effectiveness and scope of ultrasonic application technology. Due to the wide application range of ultrasonic technology and the endless emergence of new ultrasonic technologies, there are also many types of corresponding ultrasonic transducers.
Ultrasonic technology emerged in the early 20th century. It is a comprehensive high-tech discipline based on classical acoustic theory and combined with achievements in electronics, materials science, signal processing technology, radar technology, solid state physics, fluid physics, biotechnology, computing technology and other fields. The development history of nearly a century shows that Ultrasonics is an active part of acoustic development, It has not only been widely applied in some traditional industrial and agricultural technologies, but also penetrated into high-tech fields such as national defense, biology, medicine, and aerospace.
Ultrasonics mainly studies the generation, transmission, reception, information processing and related effects of ultrasound in different media. Ultrasonic physics and ultrasonic engineering are two main aspects of Ultrasonics. Ultrasonic physics is the basis of ultrasonic engineering, which provides theoretical basis and experimental data for various ultrasonic engineering applications. The research content of ultrasonic engineering mainly includes the generation Engineering design and process research of transmission and reception systems. When ultrasound propagates in a medium, it generates many physical, chemical, and biological effects. At the same time, non-destructive testing is achieved due to its strong penetration, good directionality, large information carrying capacity, and easy implementation of fast and accurate online detection and diagnosis. Therefore, it has been widely applied in industries, agriculture, national defense, biomedicine, and scientific research.
