Abstract
A MEMS acoustic transducer, for example, a microphone, includes a substrate provided with a cavity, a supporting structure, fixed to the substrate, a membrane having a perimetral edge and a centroid, suspended above the cavity and fixed to the substrate the membrane configured to oscillate via the supporting structure. The supporting structure includes a plurality of anchorage elements fixed to the membrane, and each anchorage element is coupled to a respective portion of the membrane between the centroid and the perimetral edge of the membrane.
