摘要

Sound converter or loudspeaker has additional members for acoustic resonance reduction. Additional members (6-8) are located mostly at rear or side of sound converter drive (2,3) and are of non-galvanic, i.e. electrically and magnetically conductive material.Additional members comprise geometrical shape, preferably hemispherical hexagonal, round, conical, pyramidal or prismatic and are of natural and/or crystalline material. They may be fixed directly to boundary faces of sound converter drive.
