A number of important problem and limitations for the engineering design of the high power ultrasonic vibrating systems are further analyzed and emphasized.The factors affecting the electro-acoustical efficiency of the high power transducers under different load conditions are dis-cussed,and some instructive design criterion and conclusions are obtained which can help to im-prove the performance of the high power ultrasonic vibrating systems.The new developments for the high power ultrasonic vibrating systems are reviewed,and especially two types of high power ultrasonic vibrating systems are stressed,i.e.,the three-dimensional ultrasonic radiators and the radially sandwiched piezoelectric ultrasonic vibrating systems,and the design considerations are discussed which are helpful for their engineering design.
