ULTRASOUND MAGNETOSTRICTION CONVERTER Russian patent published in 2008 - IPC B06B1/08 H04R15/00 

FIELD: mechanics; physics.

SUBSTANCE: device includes actuator winding and magnetic guide assembled of monolith plates, each plate formed of central element in ring shape and several half-wave double-pin "П"-shaped elements located at the ring periphery, where ring and pins have the same width, and outer pin ends are interconnected by a bridge. Each "П"-shaped element is mounted so that lengthwise symmetry axis of one of its two pins is tangential to middle ring perimetre with length mainly multiple of half of ultrasonic wavelength in material of magnetic guide plates. In each "П"-shaped element second pin is tilted at sharp angle to the first pin, and its outer side surface is mainly tangential to inner ring surface of central element, and its lengthwise symmetry axis crosses lengthwise symmetry axis of first pin in a point within ring area of central element. Each pin within the area from loose end to crossing point of its lengthwise axis with middle perimetre of central element has length of half of ultrasonic wavelength. Pin bridges are made mainly in a ring section form, with ring centre coinciding with ring centre of central element, magnetic guide plates are mainly grouped in sections, and adjacent sections are mainly displaces along a circle against each other at an angle equal or multiple of angle between "П"-shaped element pins.

EFFECT: improved functional and technological capacity.
