发明名称 Sound Transducer Arrangement
摘要 A sound transducer system is provided having a piezoelectrically active electret material between a first and a second electrode structure. The electret material is applied on the first electrode structure, so that the first electrode structure is completely covered with the electret material. The second electrode structure is situated on or above the electret material, so that the electret material is situated between the first and second electrode structure. The first electrode structure is configured from a plurality of electrode elements that are addressable independently of one another. The electrode elements thus define the individual sound transducer elements, which together form a sound transducer system, also designated an array. The first electrode structure is configured on a surface of a multilayer circuit bearer.
