Abstract:
1. A method for manufacturing a sound transducer structure, comprising: applying membrane support material on a first main surface of a membrane carrier material; applying membrane material in a sound transducing region and an edge region on a first main surface of the membrane support material opposite the first main surface of the membrane carrier material; applying counter electrode support material on a first main surface of the membrane material opposite the first main surface of the membrane support material; producing a plurality of recesses in a first main surface of the counter electrode support material opposite the first main surface of the membrane material in the sound transducing region; applying counter electrode material on the first main surface of the counter electrode support material; and removing membrane carrier material and membrane support material in the sound transducing region to a second main surface of the membrane material abutting on the first main surface of the membrane support material.
