YP-7015-4GZ 15Khz Ultrasonic Oscillator
Ultrasonic booster can change the amplitude of transducer. Booster is a passive deviceand cannot produce vibration itself. It is only to output after the input vibrationis changed into amplitude, and finishing the impedance conversion at the sametime. Under the stimulus of electric field, ultrasonic transducer can produce regularvibration and the amplitude is about 10μmm commonly. That is not enoughto finish the welding and processing step directly. Through with the suitable booster, the amplitude of ultrasonic can be changed ina 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, whichis equal to a rest section. This section is named nodal point, which is the best-fixedpoint of the oscillator. To departure from the fixed point, it will reducethe work efficiency of the oscillator. In the general, the transform efficiency of aluminum booster is high but the intensionof material is low and easy to cracking and easy to slipping from the hole of screw;the intension of the steel booster is high but the sound impedance is largecomparatively; the all round properties of the titanium alloy booster is good butthe price is high and the processing is difficult.
