28KHZ/40KHZ 50W Ultrasonic Vibrating Dual Frequency Ultrasonic Transducer For Auto Parts Ultrasonic Cleaner

28KHZ/40KHZ 50W Ultrasonic Vibrating Dual Frequency Ultrasonic Transducer For Auto Parts Ultrasonic Cleaner

The two resonance frequencies of the dual frequency ultrasonic cleaning transducer vibration system are significantly lower than those of a single Ultrasonic transducer, which may be related to the difference in the shape of the vibration system and the individual parameters of the transducer, but the frequency band of the vibration system is wide, which is conducive to the stability of the system. According to the research on the influence of the position of the ceramic plate in the transducer of the ultrasonic cleaner on the performance of the transducer, the piezoelectric ceramic plate is placed near the vibration node of the transducer. According to the design theory of sandwich composite transducer for ultrasonic cleaner, by properly changing the structure mode of the transducer, it can work at both the fundamental frequency and the primary harmonic frequency, that is, dual frequency transducer. There are two vibration modes of dual frequency transducer, the fundamental frequency vibration is half wavelength, and there is a node in the transducer; The harmonic vibration is a full wavelength structure, and there are two nodes in the transducer.
