Abstract Topic To possess the acoustic emission property of high efficiency with broadband, highThe power sending wave being possible, at the same time the underwater ultrasonic tolan of small-sized light weightsujiyusa is offered. Solutions In piezoelectric ceramic layered product 11 compressed stressVolt/bolt 14 in addition front mass 13 and rear mass 12The underwater where it possesses the borutomeranjiyuban vibrator which is engagedIn the ultrasonic transducer, the front mass 13 agoTo provide the crevice on the surface, the front on the mass 13 front crookedness diaphragm 13 with powerful adhesive and volt/bolt 16, or electron beamIt locks with arrival. As for crookedness diaphragm 15 piezoelectric ceramic layered productRigid body translation displacement and crookedness with the expansion and contraction of 11 diaphragm 15 itselfIt has the crookedness displacement of peripheral support. You design crevice size optimumly, are densere and others two modes of vibration that try are superimposed, band widening the figureru. Joint between the mechanism elements with volt/bolt and the like firmly the actionThe te time, also mechanical strength is strong the sufficient withstanding for also the high power sending waveYou can obtain the transducer of the small-sized light weight which can.
