Beschreibung
Zusammenfassung:	An acoustic device including a membrane having an edge. A membrane support is attached to the edge of the membrane. A central region of the membrane is unsupported by the support. A first electrode and the membrane support are manufactured as a single element. The first electrode is disposed parallel to the membrane. The membrane is configured to respond acoustically to a varying first electric field emanating from the first electrode when a varying first voltage is applied to the first electrode. A coating is deposited on a surface of the first electrode facing the membrane.
