ultrasonic transducer impedance matching 28khz/40khz frequency cleaning

Why do ultrasonic transducers array to achieve or enhance some electro-acoustic performance (directivity, action distance), arrange multiple ultrasonic transducers according to certain rules and shapes to form an array, it becomes the array of ultrasonic transducers, referred to as the array. Arrangement of certain rules and shapes to form an array will become the transducer array, referred to as the array. According to the shape, it can be divided into plane array, cylindrical array, spherical array and linear array. According to the shape, it can be divided into plane array, cylindrical array, spherical array, linear array and conformal array.

Composite rod ultrasonic transducer (Langevin transducer, Tonpilz transducer transducer), the rear cover plate using heavy metals, the front cover plate using light metals, to obtain a higher front-back vibration speed ratio. Prestressed bolts can achieve high power output by prestressing. The front cover plate is horn-shaped, which can increase radiation area and adjust Q front cover plate to be horn-shaped. The bidirectional radiation composite rod transducer is characterized by large power capacity, high efficiency, easy formation of broadband, simple and compact structure, hydrostatic resistance and easy formation of arrays. It is mainly used in active detection, communication sonar array, torpedo acoustic guidance array and so on. It is mainly used in active detection, communication sonar array, torpedo acoustic guidance array and so on.
The displacement amplification function of bending ultrasonic transducer and bending ultrasonic transducer. Seven common flexural transducers. Rare earth IV flexural transducer, rare earth IV flexural transducer, new type flexural transducer. Features: Low frequency, high power, small size, light weight, etc. It is mainly used in low-frequency active sonar and various low-frequency underwater acoustic experiments.
