Beschreibung
Zusammenfassung:	A liquid droplet production apparatus comprising a perforate membrane and an actuator. The actuator is configured to vibrate the perforate membrane such that a liquid in contact with the perforate membrane during use is caused to pass through at least one aperture of the perforate membrane and to be ejected as liquid droplets from the perforate membrane. The perforate membrane includes one or more stiffening structures for increasing the stiffness of the perforate membrane, the one or more stiffening structures each being defined by a local transverse deformation of the perforate membrane. A removable cartridge, a perforate membrane, an actuator assembly for use in such a liquid droplet delivery apparatus, and a method of manufacturing a perforate membrane for such a liquid droplet apparatus.
