Abstract
A microelectromechanical system includes a housing with an access opening and a sound transducer with a membrane and a backplate, wherein the sound transducer is coupled to the access opening. The microelectromechanical system includes a filter arranged between the access opening and the sound transducer and includes a filter material and a pretension element, the pretension element being mechanically connected to the filter material, and wherein the pretension element produces stress in the filter material in order to provide a bending deformation of the filter in a direction away from the backplate.
