Abstract
A microelectromechanical microphone includes a reference electrode, a first membrane arranged on a first side of the reference electrode and displaceable by sound to be detected, and a second membrane arranged on a second side of the reference electrode, said second side being situated opposite the first side of the reference electrode, and displaceable by sound to be detected. A region of one from the first and second membranes that is displaceable by sound relative to the reference electrode, independently of said region's position relative to the reference electrode, can comprise a planar section and also an undulatory section adjoining the planar section and arranged in a region of overlap one of the first membrane or the second membrane with the other one of the first membrane and or the second membrane.
