| titleOfInvention | METHOD AND DEVICE FOR AUTOMATICALLY ADAPTING THE INDEPENDENCE OF AN ELECTRO-ACOUSTIC TRANSDUCER |
| abstract | THE SUBJECT OF THE INVENTION IS A METHOD AND A DEVICE FOR AUTOMATICALLY ADAPTING THE IMPEDANCE OF AN ELECTRO-ACOUSTIC TRANSDUCER. A DEVICE ACCORDING TO THE INVENTION FOR ADAPTING THE IMPEDANCE OF AN ELECTRO-ACOUSTIC TRANSDUCER 3 WHICH IS EXCITED BY A TRANSMITTER 1 INCLUDES A SELF L PART AND A SECOND SELF L PART MOUNTED IN PARALLEL BETWEEN THEM AND IN SERIES OR PARALLEL WITH THE TRANSDUCER . THE SELF L IS MOUNTED IN SERIES WITH A SWITCH I. A PHASE 9 COMPARATOR EMITS A VOLTAGE E PROPORTIONAL TO THE PHASE DIFFERENCE BETWEEN THE VOLTAGE V AND THE CURRENT I CURRENT EMITTED BY THE TRANSMITTER. A CIRCUIT 11 CONVERTS THIS VOLTAGE INTO PERIODIC SIGNALS WHICH ARE EMITTED A TIME T AFTER EACH ZERO CROSSING OF CURRENT I THROUGH SELF L. AN APPLICATION IS THE EQUIPMENT OF ACTIVE SONAR ANTENNAS TRANSMITTING IN MODULATED FREQUENCY IN A WIDE BAND. |
