Abstract:

On the basis of the piezoeffect equations an expression for an electrical impedance of the flat piezotransducer loaded on the environment through a contact layer of a liquid has been received. It is shown that presence of a thin strongly reflecting contact layer leads to that the spectrum of natural frequencies becomes not the equidistant, and good quality of oscillations10 times more, than in a case flat piezotransducer loaded immediately on the environment.
