Abstract
An apparatus for sound detection, sound localization and beam forming comprises a display and a plurality of microphone stacks, wherein the display surrounds each microphone stack in lateral directions. The apparatus further comprises a plurality of elastic connectors, wherein each elastic connector surrounds one respective microphone stack in lateral direction and mechanically connects the respective microphone stack with the display. Each microphone stack further comprises a microelectromechanical transducer array, the transducer array comprising a plurality of membranes, in particular nano-membranes, and corresponding integrated back-volumes, the back-volumes being arranged under the membranes. An optical reading device is configured to separately detect the displacement of each membrane.
