FIELD: physics. ^ SUBSTANCE: electromagnetic-acoustic transducer has a housing, magnetic system, a substrate and an inductance coil. There is groove around the substrate into which an elastic sealing ring is fit, where said ring is made from rubber or polyurethane, for example, which projects from the surface of the substrate by a value equal to the given manufacturing clearance between the control object and the substrate of the electromagnetic-acoustic transducer. ^ EFFECT: high efficiency of the air cushion of the electromagnetic-acoustic transducer. ^ 2 dwg |
