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.

Abstract: A membrane component comprises a membrane structure comprising an electrically conductive membrane layer. The electrically conductive membrane layer has a suspension region and a membrane region. In addition, the suspension region of the electrically conductive membrane layer is arranged on an insulation layer. Furthermore, the insulation layer is arranged on a carrier substrate. Moreover, the membrane component comprises a counterelectrode structure. A cavity is arranged vertically between the counterelectrode structure and the membrane region of the electrically conductive membrane layer. In addition, an edge of the electrically conductive membrane layer projects laterally beyond an edge of the insulation layer by more than half of a vertical distance between the electrically conductive membrane layer and the counterelectrode structure.

Abstract: A structure for fixing a membrane to a carrier including a carrier; a suspended structure; and a holding structure with a rounded concave shape which is configured to fix the suspended structure to the carrier and where a tapered side of the holding structure physically connects to the suspended structure is disclosed. A method of forming the holding structure on a carrier to support a suspended structure is further disclosed. The method may include: forming a holding structure on a carrier; forming a suspended structure on the holding structure; shaping the holding structure such that it has a concave shape; and arranging the holding structure such that a tapered side of the holding structure physically connects to the suspended structure.

Abstract: An acoustic wave detector may include: an exterior housing with an exterior housing wall, a gas chamber located within the exterior housing and configured to receive a gas therein. The exterior housing wall may include an aperture providing a gas passage between the gas chamber and the exterior of the acoustic wave detector. The acoustic wave detector may further include an excitation element configured to selectively excite gas molecules of a specific type in the gas received in the gas chamber in a time-varying fashion, thereby generating acoustic waves in the gas, and an acoustic wave sensor configured to detect the acoustic waves generated in the gas and acoustic waves generated outside of the acoustic wave detector. The acoustic wave sensor may have an acoustic port overlapping with the aperture in the exterior housing wall.
