A micromechanical sound transducer system includes a substrate that includes (a) a cavity with a cavity edge area, (b) a front side, and (c) a rear side; a piezoelectric vibrating beam that is elastically suspended on the front side and that extends across the cavity; and, for the piezoelectric vibrating beam, a respective deflection limiting device that is on a front edge area of the respective vibrating beam and that is configured to limit a deflection of the respective vibrating beam to a limiting deflection by causing the respective front edge area of the respective vibrating beam to interact with the cavity edge area or an opposing front edge area of another vibrating beam.
