ABSTRACT:
A method for producing an ultrasound transformer as a single integral unit that includes a piezoelectric transformer element coupled to an acoustical matching layer formed from an elastomer capable of vibrating. The method includes the steps of: producing an elastomer body from a molded part which has centering contours; positioning the transformer element into the elastomer body; centering the transformer element with the centering contours; and, coupling the transformer element to the matching layer.
