Abstract (en)
[origin: EP0390959A2] The invention relates to an ultrasonic transducer with a piezoelectric transducer element which can be excited to radiate ultrasonic oscillations. Whereas previously the approach has been to overdimension the adapter body in the direction of the diameter, the approach in the invention is to achieve an effective, smallest-possible diameter of the adaptor body by adapting the lateral circumferential area of the adaptor body. <IMAGE>
