METHODS AND DEVICES FOR CONTROLLING THE VIBRATION OF ULTRASONIC TRANSMISSION COMPONENTS |
摘要 |
A transducer assembly in accordance with the present invention includes at least one transducer element having a first end and a second end. A first electrode is coupled to the first end and a segmented electrode is coupled to the second end. The segmented electrode is adapted to allow the transducer element to be simultaneously driven by a plurality of electric signals. A generator in accordance with the present invention includes a frequency control loop to generate an electrical signal having a desired level of vibration. A first amplifier having a selected gain receives the electrical signal from the frequency control loop. The first amplifier generates a first output signal to drive the transducer element. A second amplifier having a selected gain receives the electrical signal from the frequency control loop. The second amplifier generates a second output signal to drive the transducer element.
