Abstract
Technologies are provided for microelectromechanical microphones that can be robust to substantial pressure changes in the environment in which the micromechanical microphones operate. In some embodiments, a microelectromechanical microphone device can include a rigid plate defining multiple openings that permit passage of a pressure wave. The microelectromechanical microphone device also includes a stiffener member integrated into the rigid plate. The stiffener member causes stress to be distributed within the rigid plate in response to the pressure wave inducing deformation of the rigid plate.
