<p>An ultrasonic converter comprises piezocells (1) interconnected in series by electric signal transmitting circuits (2) serving as phase shifters, and a circuit (4) for control of the acoustic wave inclination angle the outputs of which are connected to the phase shifters. A circuit (8) is connected in series to each piezocell to form the signal amplitude on the corresponding piezocell (1).</p> |
