Microelectromechanical device and microelectromechanical loudspeaker

A microelectromechanical loudspeaker, comprising:

• a microelectromechanical device for generating a fluid pressure, including:
• a displacer unit including a movable displacer element which can be deflected to generate the fluid pressure using a drivable connecting element acting on the displacer element,
• wherein the connecting element has a base structure and a coupling structure connected to the base structure for connecting the connecting element to the displacer element, and wherein the base structure includes a mass reduction portion with a material recess,
• wherein the displacer unit is configured to generate sound pressure as the fluid pressure;
• and
• a signal processing unit configured to apply and process signals from the microelectromechanical device.
