The paper deals with an influence of a piezoelectric beam geometric dimensions on the primary parameters of piezoelectic constructions. Such parameters as resonance and antiresonance frequencies as well as electromechanical coupling coefficient are investigated. Optimal piezoelectric beam length and width relations are obtained. In conclusion some thoughts on piezoelectric beams practical applications in hydroacoustics are discussed.
