A method for aerosolizing a liquid comprises providing an aerosol generator (16) having a plate (20) with a plurality of apertures and a piezoelectric element (22) to vibrate the plate (20). Liquid is supplied to the plate (20) and the piezoelectric element (22) is energized to vibrate the plate (20) at an initial frequency. The energy level is adjusted to vibrate the plate at its instantaneous resonant frequency during aerosolization of the liquid.
L'invention porte sur un procédé de transformation d'un liquide en aérosol utilisant un générateur d'aérosols (16) présentant une plaque (20) percée de multiples ouvertures et un élément piézo-électrique (22) faisant vibrer la plaque (20). Le liquide étant fourni à la plaque (20), on excite l'élément piézo-électrique (22) à une fréquence initiale pour faire vibrer la plaque (20), puis on règle le niveau de puissance pour faire vibrer la plaque à sa fréquence de résonance instantanée pendant la production de l'aérosol à partir du liquide.
