Abstract
In an exemplary embodiment, transducer combs for ultrasonic arrays or compound scanners, which consist of a specifiable number of transducer elements, are produced by a technically particularly simple and cost-saving manufacturing process, with the following method steps: PA0 (a) a plurality of thin strips of transducer element material, in particular, piezo-material, are combined by cohesive bonding into a stack; e.g. on the basis of alternate interpositioning of spacing strips or on the basis of application of spacer beads on the transducer strips of piezoelectric material, PA0 (b) from the stack thus formed, individual packets are cut off transversely to the transducer strips, PA0 (c) each individual packet is completed as a transducer comb by itself.
