The problem of sound wave receiption is solved for the case of transducer with fully electrodized active surface. The solution is obtained on the base of spherical electroelastic model for the piezoelastic transducer in the form of thin shell filled with acoustic medium with the method of partial domains, using the Fourier method, the properties of completeness and orthogonality of the spherical wave functions and matching of the fields on the boundaries of sub-domains. The expansion coefficients for sound, mechanical and electrical fields and the annular layer are found.
