English abstract:
A microelectromechanical loudspeaker may include: a plurality of elementary loudspeakers each including a drive unit and a diaphragm deflectable by the drive unit, and a controller configured to respectively supply control signals to the drive units. The drive units may be respectively configured to deflect the corresponding diaphragms according to the respective control signals supplied by the controller to generate acoustic waves. The control signal supplied to at least one control unit may have at least one local extremum and a global extremum of a curvature of the control signal with a highest absolute value of the curvature may be located at a position ofthe control signal preceding a position ofthe at least one local extremum of the control signal
