A transducer method for ultrasonic liquid treatment, in which a first transducer and a second transducer are respectively arranged at both ends of a vibrating pipe body, and the length of the vibrating pipe body is selected as the working frequency of the first transducer and the second transducer Corresponding to an integer multiple of the equivalent half-wavelength, the axial vibration of the first transducer and the second transducer is converted into radial vibration, and the ultrasonic energy is converged in the tube to apply strong ultrasonic energy to the liquid in the tube. The transducer device for ultrasonic liquid treatment includes a vibrating tube body, a first transducer, a second transducer arranged at both ends of the vibrating tube body, and an ultrasonic generator for driving the transducer. The vibrating tube body can convert the vibration generated by the transducer along the axial direction of the vibrating tube body into vibration along the radial direction of the vibrating tube body, so that the ultrasonic energy can concentrate on the liquid in the tube. The device of the present invention has simple equipment structure, high reliability and convenient use, and can be widely used in the fields of object cleaning, emulsification, crushing, sonochemistry, extraction of Chinese herbal medicines, bioengineering and the like.
