Abstract: A method for producing an ultrasound transducer having piezoelectric or electrostrictive ceramic elements (11) embedded in plastic, with reduced production costs. The ceramic elements (11) are ceramic rods (20) provided with a plastic jacket (21) of a constant thickness, and the jacketed ceramic rods (20) are organized, while standing upright, in a container (31) that is open on one side and is vibrated. The container (31), with the jacketed ceramic rods (20) is filled with a plastic, such as resin or PU. After hardening, the resulting composite body (12) is removed from the container (31), and its top side and/or underside (121, 122) is ground down until the ceramic rods (20) possess a length stipulated by the necessary transducer frequency. Electrodes contacting all or only groups of the ceramic rods (20) are subsequently mounted to the topside and underside (121, 122) of the composite body.

Abstract: A method for producing an ultrasound transducer having ceramic elements (11) that are embedded in plastic and comprise piezoelectric or electrostrictive ceramic, with the method steps being executed for reducing the production costs. The ceramic elements (11) are produced as ceramic rods (20) that are provided with a plastic jacket (21) of a constant thickness, and the jacketed ceramic rods (20) are organized, while standing upright, in a container (31) that is open on one side and is subjected to vibratory movements. The container (31), with the jacketed ceramic rods (20) is filled with a plastic, such as resin or PU, the resulting composite body (12) is removed from the container (31) after hardening, and its top side and/or underside (121, 122) is or are ground down until the ceramic rods (20) possess a length stipulated by the necessary transducer frequency.
