Acoustic properties of cylindrical piezoceramic emitters with power and compensated design with longitudinal and transverse piezoe-lectric effect
Main Article Content
Abstract
The numerical analysis of the properties of sound fields, generated by cylindrical piezoceramic transducers, power and compensated design has been done. Different compaunds of piezoceramics and various schemes of constructing oscillation systems has been analyzed, allowing to implement in the transducer longitudinal or transverse piezoeffect. The influence in the sound field made by the changes in the geometric form of the transducer has been discovered. Comparative analysis of the frequency dependence of the sound fields allowed us to establish a number of subtle effects in their formation, depending both on the type of construction, and the kind of the piezoelectric effect and compound of piezoceramics used.
