A microelectromechanical loudspeaker array includes a plurality of microelectromechanical loudspeaker elements each having a diaphragm element configured to be deflected from a neutral position into at least one deflection position to produce a sound pulse. The array further includes an actuation device which is configured to put the diaphragm element into the at least one deflection position from the neutral position on the basis of drive signals. The array further includes a control device coupled to the plurality of loudspeaker elements. The control device is configured to send, in each case at a driving time, (i) a first drive signal configured to produce a sound pulse by actuating the diaphragm element, and (ii) a respective second drive signal configured to relax the diaphragm element into the neutral position during a predetermined period of time after the driving time to the actuation device of at least one of the loudspeaker elements.
A microelectromechanical loudspeaker array, comprising:
A method for operating a microelectromechanical loudspeaker array having a plurality of microelectromechanical loudspeaker elements, the loudspeaker elements each having a respective diaphragm element configured to be deflected from a neutral position into at least one deflection position to produce a sound pulse and a respective actuation device configured to return the diaphragm element to the at least one deflection position from the neutral position on the basis of drive signals, the method comprising:
