ELECTROMAGNETIC ACOUSTIC TRANSDUCER

摘要

An electromagnetic acoustic transducer comprises two mounted in parallel magnetic guides between which a magnet is arranged from one side, and from other side a flat conductor emitter which principal plane is normal to main axes of the magnetic guides. The magnetic guides comprise a set of elements with low magnetic resistance as flat parallel magnetoconductive plates normal to the plane passing through the main axes of the magnetic guides and mounted displaceably relative to each other in direction normal to the conductor emitter principal plane.
