Abstract
An electrostatic pressure-gradient microphone capsule to be mounted essentially flush in or behind especially flat mounting surfaces includes a capsule housing with two sound inlet openings which may be divided, a diaphragm tightly mounted on a diaphragm ring, an electrode and possibly an acoustic friction. The two sound entry openings are arranged on one side of the capsule housing, i.e., the front side, and one sound entry opening is connected acoustically conductively with the front side of the diaphragm and the other sound entry opening is connected acoustically conductively with the rear side of the diaphragm, and the diaphragm is arranged essentially parallel to the front side.
Claims6
