Ultrasonic horn
The ultrasonic horn is an important part of the ultrasonic vibration system. Its main function in the vibration system is to amplify the displacement or velocity of the particle of the mechanical vibration, and concentrate the ultrasonic energy on a small area, which is energy gathering. Also called ultrasonic shift lever or ultrasonic concentrator.
As the name implies, the ultrasonic horn is a functional component that cooperates with the ultrasonic transducer to change the amplitude of ultrasonic vibration. Its main function is to change the amplitude of the transducer (generally increase), improve the vibration speed ratio, improve efficiency, improve the mechanical quality factor, strengthen heat resistance, expand the temperature range, and extend the life of the transducer.
The ultrasonic transducer adjusts the load matching between the transducer and the ultrasonic tool head by installing the ultrasonic horn, reduces the resonant impedance, makes it work at the resonant frequency, improves the electro-acoustic conversion efficiency, and effectively reduces the ultrasonic transducer. The heat generation of the device increases the service life.
