1. A method of manufacturing a vibratable membrane for use in an aerosol generator for generating an aerosol from a fluid, comprising:
providing a vibratable membrane having a first side for contact with the fluid and an opposite second side, and
providing the membrane with a plurality of through holes penetrating the membrane from the first side to the second side, whereby the fluid passes the through holes from the first side to the second side when the membrane is vibrated for generating the aerosol at the second side, each through hole having a nozzle portion, wherein
a ratio of a total length of each through hole to a length of the nozzle portion is at least 4, and wherein
the through holes are formed using an electroforming process.
