Abstract

The invention relates to a device (1) for generating a medium stream, having a chamber (4), which chamber (4) comprises chamber walls (2, 3) lying opposite one another and at least one medium opening (27, 28, 29, 30) for the medium stream, which medium stream can be generated in the chamber (4) by means of a diaphragm (5), which diaphragm (5), in an inactive operating state of the device (1), is arranged substantially untensioned in the chamber (4) between the chamber walls (2, 3) lying opposite one another, and associated with which diaphragm (5) is a drive device (6), responsive to electrical drive signals, for driving the diaphragm (5) to deform the same, the drive device (6) being designed to impose a deformation on the diaphragm (5) in an active operating state of the device (1), during which deformation the diaphragm (5) has an inner mechanical tension.
