Abstract
A MEMS device comprises a housing with an interior volume, wherein the housing includes an access port to the interior volume; a MEMS sound transducer in the housing, and a mechanical barrier structure having a plate element that is fixed by elastic spacers to a carrier and overlaps the access port, and providing a ventilation path passing a boundary region of the plate element, wherein a clearance of the ventilation path is set by the distance of the boundary region of the plate element to the housing or by the distance of the boundary region of the plate element to a blocking structure that opposes the boundary region of the plate element.
