ELECTROMAGNETIC ACOUSTIC CONVERTER Russian patent published in 2005 - IPC

FIELD: ultrasound control of materials.

SUBSTANCE: device has body, substrate, lid, concentrators, constant magnets and inductive coils. It is also provided with at least two couples of ferromagnetic concentrators, placed in parallel to each other, in each pair concentrators are mounted symmetrically to each other relatively to at least one flat constant magnet, made, for example, of connection Ne-Fe-B and enveloped by electromagnetic coil, connected to source of pulse constant current. Concentrators are made in form of cylindrical ferromagnetic rods and fixed in on substrate of non-magnetic material with possible vertical displacements in bushings of ferromagnetic material, pressed to opposite sides of constant magnet.

EFFECT: higher reliability and efficiency.
