1. A pressure-balanced electromechanical converter including a structure that converts displacement into electrical energy or electrical energy into displacement, said structure designed to separate an enclosed volume from an outside pressure wave channel, wherein said enclosed volume has a filtering, pressure transparent connection to said outside pressure wave channel with said filtering connection being pressure transparent to static pressure or low frequency pressure waves and attenuating pressure waves at higher frequencies and wherein at least part of the enclosed volume forms a Helmholtz resonator for the higher frequencies.
