The paper considers the energy balance in an electroacoustic converter of a new type, gives expressions of power for instantaneous and average for the period oscillations of the values of conduction and displacement currents. It is shown that the only source of energy in the electroacoustic conversion under consideration is the conduction current with a non-zero average power. A rather trivial conclusion is made about the obligatory presence of ions in the working fluid of an electroacoustic transducer. It is shown that the average power of the conduction current in the specified converter is close to or equal to zero. This happens either due to the fulfillment of the conditions of applicability of the electrohydrodynamic equations, or due to the phase difference between the oscillations of the displacement current density and the electric vector, or for both reasons at the same time. The obtained results can be claimed in the design of emitters of a new type.
