ABSTRACT:
A corona effect sound emitter including a discharge electrode producing corona discharge and surrounded by a spherical counter electrode is partially inserted in a housing which encloses a high frequency generator, modulation transformer and a power supply transformer of which the power supply transformer supplies the discharge electrode with electric current. A thin plate of a magnetic metal transversally extends in the housing so that secondary windings of the transformers are positioned above the plate and are separated from the primary windings of the transformers disposed below the plate.
