Abstract

The invention generally relates to drives for microelectromechanical acoustic pressure-generating device, which may be implemented in a microelectromechanical system (MEMS). In some embodiments of the invention, the microelectromechanical acoustic pressure-generating device is implemented in a chip/die, e.g. in form of a System-on-Chip (SoC) or a System-in-Package (SiP). Further embodiments of the invention relate to the use of such acoustic pressure-generating device in a microelectromechanical loudspeaker system, for example, headphones, hearing-aids, or the like. Embodiments of the invention relate to the miniaturization of the device. Some of the embodiments focus on countermeasures that reduce the pull-in force, which can facilitate further miniaturization of the microelectromechanical acoustic pressure-generating device.
