Abstract

The invention concerns a method for realising an acoustical transformer 1. The acoustical transformer 1 has a first transformer element 4 and a second transformer element 8. The acoustical transformer 1 is arranged in association with a pattern card 2. In the pattern card 2 there is arranged at least one cavity 5, 13, in association with which the first transformer element 4 is placed, and at least one part of the second transformer element 8 is supported against the pattern card 2. <IMAGE>
