Abstract
Improvements in the systems for the underwater emission of frequency-modulated oscillations, for the purposes of message transmission, with a microphone, a preamplifier, an oscillator, a final stage and an energy irradiator, characterized in that the oscillator has two monostable multivibrators ( 3, 4), because the output of the first multivibrator (3) is connected to the input of the second multivibrator (4) and the output of the second multivibrator (4) is connected to the input of the first multivibrator (3), because the voltage of the modulation produced in the preamplifier (2) is conducted through a resistor (29) the capacitor (26) of the filter of resistance and capacity of at least one of the multivibrators, and because the energy irradiator is a piezoelectric transducer (3) ) to produce ultrasonic waves in the water as a function of the signals fed by the final stage (7) to the transducer.
