Ultrasonic Oscillator

Ultrasonic booster can change the amplitude of transducer. Booster is a passive device
and cannot produce vibration itself. It is only to output after the input vibration is changed into amplitude, and finishing the impedance conversion at the same time. Under the stimulus of electric field, ultrasonic transducer can produce regular vibration and the amplitude is about 10μmm commonly. That is not enough to finish the welding and processing step directly.

Through with the suitable booster, the amplitude of ultrasonic can be changed in
a large range. If the material is enough intensive, the amplitude can exceed 100μmm. We named oscillator after connecting ultrasonic transducer with booster. On the other hand, when the booster works vibration through longitudinal and extension, on the both sides of the particle direction of motion is the opposite, which
is equal to a rest section. This section is named nodal point, which is the best-fixed point of the oscillator. To departure
