FIELD: engineering of acoustic and sound-reproducing equipment. ^ SUBSTANCE: in proposed isotropic electro-hydro-acoustic emitter, including magnetic circuit with constant magnet and core, source of sound oscillations, mobile system with sound coil and flexible outputs, as source of sound oscillations, resilient spherical element is used held in intermediate chamber having draining branch pipe and positioned above conic chamber filled with resilient spherical grains and having perforated surfaces: immobile upper surface, on which outlet branch pipe is mounted, and mobile lower one, to which stepped rod is connected, lower end of which rod is rigidly connected to sound coil, mobile in vertical direction, mounted in gap between internal aperture of magnet and external surface of core, while magnetic circuit is hydro-isolated from other sections of electro-hydro-acoustic emitter, because liquid is constantly flowing through them, which is received in distribution chamber, positioned below lower perforated mobile surface of conic chamber. ^ EFFECT: achievement of spherical shape of emitted wave, resulting in ideal, in terms of naturalness of sound, directional characteristic of its radiation. ^ 1 dwg |
