ABSTRACT:
A piezoelectric transducer in the form of a spheroidal cap comprises a mosaic of individual piezoceramic elements having a height of 3 to 10 mms and a lateral extension that does not substantially exceed the height there being gaps between the piezoceramic elements which are filled with an electrically insulating material having a modulus of elasticity which is smaller by at least one order of magnitude than that of the ceramic material, with the rise of the spheroidal cap amounting to at least 5 cms and the apex angle of the corresponding spherical sector amounting to at least 60.degree..
