Patent abstract
A MEMS structure includes a backplate, a membrane, and an adjustable ventilation opening configured to reduce a pressure difference between a first space contacting the membrane and a second space contacting an opposite side of the membrane. The adjustable ventilation opening is passively actuated as a function of the pressure difference between the first space and the second space.
