Abstract
The utility model relates to an ultrasonic radiator which includes a radiator rod equipped with transducers at one or two ends of the rod. The radiator rod has circular grooves around the surface and each groove has two circular radiation surfaces facing each other. When the rod produces vibration under the stimulation of the transducers, the radiation surfaces radiate ultrasonic waves. The rod has a plurality of radiation surfaces and the total radiation area is very big. Therefore the utility model has a high electric-acoustic transducer efficiency. Since the ultrasonic wave can be radiated along the length of the rod, the processing time can be shortened and work efficiency improved. By reasonably setting the dimensions and locations of the two circular radiation surfaces facing each other in each circular groove, the vibration of the two surfaces can be basically in opposed phases and superposition of the ultra-sonic waves radiated by the two radiation surfaces will make the general radiation effect satisfactory.
