An antiplane mixed dynamic problem of electroelasticity for a piezoceramic half-space weakened by two tunnel holes is considered. Excitation of electroelastic fields occurs due to the effect of the given electrodes electric potential differences.
   The boundary problem is reduced to a system of singular integro-differential equations with discontinuous kernels which is realized by the quadrature method. Results of parametric investigations characterizing the behavior of the components of electroelastic field on the boundary and in the area of a piecewise-homogeneous half-space are given.
