    as a metal ring fitted with a fixing device for 1175352, interacting with the holder of the discharge electrode.
    The invention relates to electroacoustic transducers of electrical oscillations and fluctuations of air pressure, namely, ionophobes, which serve as transmitters of sound vibrations obtained without oscillating membranes using a strong electric corona discharge.
    The purpose of the invention is to provide an isotropic sound emission characteristic.
    FIG. 1 shows an ionophone with a firing electrode made in the form of a cap, a section in FIG. 2 the same, with the igniting electrode, made in the form of a ring; in fig. 3 ionophones installed inside the protective shell, partial longitudinal incision.
    The ionophon contains a corona-shaped electrode 1 in the form of a needle, which is located, with the exception of having a pinpoint point 2, in the holder 3 of electrode 1. The latter has a cylindrical shape and is made of a heat-resistant material with a high dielectric constant, for example of polytetrafluoroethylene. In the final section opposite the tip 2, the electrode 1 has a contact part 4, which protrudes beyond the non-working end of the holder 3 of the electrode 1.
     The coronary electrode 1 is surrounded by a spherical electrode having a spherical shape and is composed of; of two hemispherical caps (hemispheres) 5 and 6, which are interconnected at the equator by a holding device 7 having an annular shape. Both of these hemispherical parts 5 and 6 are made of finely cellular metal mesh. The size of the cells is chosen in such a way that the counter-electrolyte is permeable to sound waves, but at the same time forms the Farada cage (cylinder)
    for electromagnetic waves that originate from the corona electrode 1. Both hemispherical tips 5 and 6 of the counter electrode can be made from a thin sheet that is provided with many small holes and is shaped accordingly.
    In the hemisphere 6, an arching tool 8 is provided, which is large in the form of a ring of metal, for example, from copper or brass. Hole 8 is edged into the wall of the hemisphere 6 in the area of its top and forms an opening for the passage of the holder 3, which is installed so that the discharge electrode 1 passes along the radius rnut spherical counter electrode to a point near its center, but at a sufficient distance from the counter electrode Preventing the occurrence of an electric arc discharge. The holder 3 is fixed .in the anvil 8 with a screw 9.; The holder 3 of the electrode 1 protrudes beyond the spherical counter electrode and is placed in a metal sleeve 10, which is made, for example, of copper or brass. The sleeve 10 is inserted into the tunnel 8 and forms contact with the inner wall of the tunnel 8. The portion of the sleeve 10 protruding beyond the limits of the tunnel 8 has a larger diameter than the diameter of the portion of the sleeve 10 inside the tunnel 8, forming a shoulder providing an emphasis when the holder 3 electrodes 1 per counter electrode. Thanks to such a device, the tip 2, which has a dotted shape, reaches only the region of the center of the spherical counter electrode
    The sleeve 10 can be fixedly connected with the anvil 8 and made with it in the form of one piece, forming a continuation of the anvil 8. In this case, the holder 3 of the electrode 1 has the same shape as in Fig. 1 and is inserted into the sleeve 10. An ionizing electrode 11 is provided in the ionophone, which is installed inside the spherical counter electrode and is electrically connected to it. This ignition electrode 11 is much closer to the tip 2 than the counter electrode, thereby significantly increasing the gradient. . a high-frequency electric field with a medical tip 2. and a firing electrode 11, simplifying the ignition of the corona discharge. The ignition electrode 11 can be made in the form of a cap of finely cellular metal mesh, fixed with its top in the hemispherical cover 5 of the counter electrode at its top, with the cap cavity facing the tip 2 of electrode 1. The counter electrode (Fig. 2) is a metal ring, connected to a metallic conductor 8 with fastening posts 12 made of metal. This ring is preferably about 15 mm away from the tip 2 and has a diameter of about 3 0 mm. The sleeve 10 is equipped with a tailpiece which, with some slight effort, friction enters the nozzle 13 connected to the metal housing 14. The housing 14 also contains a circuit (not shown) generating a high frequency and high voltage signal, which is modulated by a lower signal frequency converted to sound waves. The housing 14 is provided with a contact device 15, which is made in the form of an elastic tongue, located in a certain way with respect to the opening of the nozzle 13 and connected to the output of the generator. In accordance with this design, the counter electrode is connected during operation through the passage 8, the sleeve 10 and the nozzle 13 with potential earth, while the corona electrode 1 is electrically connected to the output of the high-frequency generator through the contact part 4 and the elastic tongue 15. The sleeve 10 can be provided with an external thread, and side 13 - vnut renney that allows the compounds of both parts. On the other hand, the connection of the sleeve 10 with the naTjpy lump 13 can be provided with a bayonet bolt. The counter electrode (nig.Z) is completely surrounded by a spherical protective sheath of considerable diameter. The protective sheath is provided with openings of sound-permissive material and may consist, for example, of two hemispherical tongs 16 and 17, which are fastened along the equator line by connecting elements 18 and 19, so that both hemispherical cracks 16 and 17 are kept in a connected state screws 20. In the wall of one hemispherical cover 17 there is an additional metal passage 21 | filled in the form of a ring, {located at the top of this cover, forming a passage for the sleeve 10 of the electrode holder 3. The sleeve 10 is fixed in the holes e 21 by a screw 22. The two hemispherical covers 16 and 17 are made of metal. They thus form the second Farad cell around the spherical counter electrode, so that all leakages dp of the penetration of electromagnetic waves outside are eliminated. The protective sheath prevents the hand from touching the counter electrode, which is heated during operation to a relatively high temperature due to a corona discharge on the tip of 2 electrodes 1. Both protective covers 16 and 17 are covered with a cloth 23, which suppresses sound and prevents the ionophone from dust. , and also shields the light from the corona discharge. The sleeve 10 or nozzle 13 may be surrounded by a reflector 24, as shown by the dash-dotted line in FIG. 1. The surface of this reflector 24 has a profile of an overturned exponent, so that the downward-directed sound waves (Fig. 1) are reflected in the desired direction. In another embodiment, the body 14 is covered with a porous material based on plastic or rubber or other appropriate sound absorbing material. Ionofon works as follows. . A high-frequency high-voltage voltage is applied to the electrodes, modulated by a lower-frequency signal, which must be converted to an asyKoiftoS signal. A corona discharge occurs between the electrodes, which causes pressure fluctuations in the air.
    Predlaera a) dt ionophone emits sound isotropic in a large spatial angle. Since the counter-electrode consists of two parts, its front part can legly be mixed, V, N ./ N g
    nats Protective sheath enhances safety. A safety circuit can be provided between it and the opposite electrode that performs emergency shutdown when an electrical connection occurs between the protective sheath and the opposite electrode, for example, 0 due to mechanical deformation of the protective electrode.
