GENERATOR OF ULTRASONIC OSCILLATIONS Russian patent published in 2021 - IPC G01N29/34 

FIELD: physics.

SUBSTANCE: invention is used for generation of ultrasonic vibrations. The essence of the invention lies in the fact that the generator of ultrasonic oscillations contains transistor half-bridges and a control unit connected to the indicated transistor half-bridges with the possibility of controlling their operation, and the said transistor half-bridges form two stages of transistor half-bridges, and said generator additionally contains electromagnetic-acoustic transducers connected to the indicated cascades of transistor half-bridges according to the matrix scheme in such a way that the electromagnetic-acoustic converters in each row of the matrix circuit are connected to the corresponding one of the transistor half-bridges belonging to one of the indicated cascades of the transistor half-bridges, and the electromagnetic-acoustic converters in each column of the matrix circuit are connected to the corresponding one of the transistor half-bridges belonging to the other cascade of transistor half-bridges, while the control unit is configured to issue specified control signals to transistor half-bridges corresponding to a given row of the matrix circuit, and transistor half-bridges corresponding to a given column of the matrix circuit, with the possibility of electric current flowing through the coil of one of the specified electromagnetic-acoustic transducers corresponding to the specified row and column of the matrix circuit, which makes it possible to generate ultrasonic vibrations to the specified electromagnetic-acoustic transducer.

EFFECT: ensuring possibility of creating an ultrasonic oscillator capable of operating in a multichannel mode.
