Definitions

the invention relates to a method for generating and emitting ultrasonic energy in liquids, in particular for sonicating ultrasonic cleaning baths by means of a sound transducer, that is to say an oscillating element with an attached rod-shaped or tubular resonator immersed in the liquid.
a sound transducer that is to say an oscillating element with an attached rod-shaped or tubular resonator immersed in the liquid.
f (25) has the length lambda / 2 (25) or an integer multiple thereof.
the sound transducer is still operated at the optimal cleaning frequency f (25) , but in addition the bathroom is sonicated with a frequency f (n) that lies outside this main frequency f (25) and an integer multiple of lambda / 2 ( 25) as well as lambda / 2 (n) .
a sound transducer is operated with a resonator corresponding to the length 5/2 lambda (25) and a specific ultrasound frequency f (25) , an additional frequency f (n) for the given resonator geometry 4/2 lambda (n) , 6 / 2 lambda, 3/2 lambda (n) or 7/2 lambda (n) .
the main frequency f (25) alternates with the additional frequency f ( n) at intervals or the additional frequency f ( n) is fed in at intervals to the main frequency f (25) .
the main frequency f (25) and the additional frequency (additional frequencies) f (n) can be continuously fed together to the resonator.
