<p>Transducer for the transformation of electrical modulations into vibratory modulations, comprising a needle-shaped discharge electrode, which is embedded, except in the region of its tip, in an electrode holder of substantially cylindrical form, made of an electrically insulating, and heat-resistant material, and a counter-electrode spaced from the discharge electrode and surrounding the latter. The counter-electrode has substantially the form of a sphere embodied in a perforated, electrically conductive material permeable to sound waves, and has a passage in which electrode holder is fitted. The discharge electrode extends radially into the interior of the spherical counter-electrode up to a point situated in proximity to the center of the sphere. The transducer thus embodied is omnidirectional.</p> |
