Abstract (en)
The transducer has a resonating tube (1) of same, common or integral front-emitting mass (5). Each tube has its own piezoceramic layer and back mass mutually fixed on opposite side by central bolts. The integral, common front mass of a transducer array (12) is fixed inside or outside of certain arbitrary or round shaped metal pipe. The pipe enables to radiate multimode sonic and ultrasonic energy externally or internally.
