Abstract
An aerosol-generating device is provided, including: a membrane having an aerosol-generation zone, in which the aerosol-generation zone includes a plurality of nozzles, the plurality of nozzles being the only nozzles in the aerosol-generation zone; and an actuator coupled to the membrane, in which the actuator is configured to excite the membrane to induce a vibration of the membrane at one or more predetermined modal frequencies of the membrane such that a liquid aerosol-forming substrate passing through the plurality of nozzles is aerosolised, in which more than 50% of the plurality of nozzles are located closer to antinodes than to nodes of the membrane, where the antinodes and the nodes correspond to the membrane being excited at the one or more predetermined modal frequencies of the membrane, and in which the membrane progressively changes in thickness from a centre of the membrane to a peripheral edge of the membrane.
