Abstract
The invention relates to an ultrasonic wave radiator, comprising radiating rod with transducer at one end or two ends. Several ring grooves are set on the radiating rod. Said ring grooves comprise two faced ring radiating faces. When the rod generates vibration under the excitation of transducer these radiating faces can radiate ultrasonic wave. Because the radiating rod has many radiating faces the total radiating area of transducer is large and conversion efficiency from electricity to sound is high. Because the whole length direction of radiator can radiate ultrasonic wave treatment time can be shortened and working efficiency can be improved. By setting dimension and position of two faced radiating faces on said ring rod reasonably vibrations of two radiating faces are opposite phase in basic so that superposition sound field formed by ultrasonic wave radiated by two radiated faces is strengthened and the whole radiating effect is good.
