Abstract
A MEMS sound transducer for generating and/or detecting sound waves in the audible wavelength spectrum includes a membrane carrier, a membrane that is connected in its edge area to the membrane carrier, and may vibrate along a z-axis with respect to the membrane carrier, and a stopper mechanism, which limits the vibrations of the membrane in at least one direction. The stopper mechanism includes at least one reinforcing element, which is arranged on one side of the membrane, and an end stop opposite to the reinforcing element. In a neutral position of the membrane, the end stop is spaced at a distance from the membrane and against which the reinforcing element abuts at a maximum deflection. A sound transducer arrangement includes such a MEMS sound transducer.
