Abstract

A MEMS sound transducer includes a backplate and a membrane held by an edge fixing such that the membrane is deflectable along a deflection direction toward the backplate. The MEMS sound transducer further includes an elevation element arranged between the membrane and the backplate and having a first height along the deflection direction. The MEMS sound transducer also includes a supporting structure and a spacer element arranged between the membrane and the supporting structure and having a second height along the deflection direction, the second height being greater than the first height. The supporting structure is the backplate or is a supporting element arranged opposite the backplate, such that the membrane is arranged between the backplate and the supporting element.
