Abstract
A MEMS sound transducer for generating and/or detecting sound waves in the audible wavelength spectrum includes a carrier: a diaphragm connected to and deflectable with respect thereto the carrier and a piezoelectric element spaced apart from the diaphragm along a reciprocation axis. The piezoelectric element includes a coupling element that extends along the reciprocation axis and connects to the diaphragm. The piezoelectric element and the coupling element form a cantilever. The MEMS sound transducer includes two cantilever arms are arranged one behind the other, in a top view.
