Abstract: A supersonic transducer including means for detecting its vibrating speed and for changing the frequency of the energizing current in response thereto. This invention utilizes the property that when an electrostrictive vibrator is vibrated resonantly, its dynamic admittance varies depending upon the difference in its stress distribution. The electrostrictive vibrator is divided into portions of large and small stresses to cancel the applied brake currents. Simultaneously, a signal is derived that is proportional to the difference of the dynamic currents so as to provide an effective energization by detecting the resonant frequency of the vibrator in order to automatically adjust the applied frequency of the supersonic transducer.
