GENERATOR OF ACOUSTIC FIELD IN SOLID BODY Russian patent published in 2017 - IPC G09B23/14 B06B1/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement equipment and can be used as a generator of graduated acoustic pulses when testing diagnostic high-frequency sensor equipment. Generator of acoustic field in a solid body includes balls having the possibility of collision with the surface of a radiator for excitation of elastic waves in it, interconnected chambers, in one of which there are metal balls of equal diameter able to be transferred into another chamber by gravity and affecting the end of the radiator in the form of a cylindrical waveguide, which is installed coaxially in each chamber on the side of the base able to move along its axis, herewith the other end of the waveguide is coupled with the analyzed object, and the chambers are formed in the housing, between which and the analyzed object there is an element of control over the waveguide displacement height in the chamber, herewith the ratio of the length of the waveguide to its diameter is more than five.

EFFECT: technical result is the possibility of formation in a diagnosed (analyzed) object in normal, as well as explosion-fire conditions, of successive acoustic pulse of dosed amplitude and duration without any devices with a drive providing collision, and without any energy sources for this purpose.
