Application Piezoelectric Transducer in Acoustic Measurement Systems

In the article highlights the infusion of additional structural elements into the characteristics of a piezoelectric electroacoustic transducer, leading to the breakdown of the structure, as well as their straightness diagrams. The major tasks of ultrasonic measuring systems are sound waves concentrated sending to the controlled object and reflected waves receiving. Electro-acoustic transducer is an oscillating system with a sufficiently high quality factor and contains an asymmetric bimorph element. The considered butts of improving the sensitivity of the central beam of the electroacoustic transducer added to the design volumetric resonator. Directional effect of concentration can be obtained using the irradiator as Helmholtz resonator consisting of bimorph piezoelectric resonator and tube of required length and diameter, which orients sound beam on the acoustic axis of the electroacoustic transducer. An example of improving the selectivity of the central lobe electroacoustic transducer is adding additional cavity resonator to the construction of the piezoelectric transducer. Further research can be carried out directly based on mathematical models for various design circuits of piezoelectric transformers. Important tasks in the design and development of the main components of ultrasonic vibrating devices are considered. The main advantages and shortcomings of the ultrasonic signal-receiving path have analyzed, in which electroacoustic converters combined with additional structural elements for ultrasonic vibrating systems to ensure autonomous vicination specification of the design parameters and military technology in open areas and intersections.
