Abstract
A method for producing an ultrasound transducer having piezoelectric or electrostrictive ceramic elements ( ) embedded in plastic, with reduced production costs. The ceramic elements ( ) are ceramic rods ( ) provided with a plastic jacket ( ) of a constant thickness, and the jacketed ceramic rods ( ) are organized, while standing upright, in a container ( ) that is open on one side and is vibrated. The container ( ), with the jacketed ceramic rods ( ) is filled with a plastic, such as resin or PU. After hardening, the resulting composite body ( ) is removed from the container ( ), and its top side and/or underside ( ) is ground down until the ceramic rods ( ) possess a length stipulated by the necessary transducer frequency. Electrodes contacting all or only groups of the ceramic rods ( ) are subsequently mounted to the topside and underside ( ) of the composite body.
