    Abstract: La présente invention concerne un générateur pour exciter un transducteur piézoélectrique, notamment destiné à pulvériser un liquide, ce générateur comportant au moins une unité de traitement numérique et étant agencé pour fonctionner au moins selon une phase de fonctionnement itérative (200) comportant plus de deux itérations successives et pour, au cours de chaque itération :
    - exciter le transducteur à une fréquence variable dans une bande de fréquences autour d'une fréquence de consigne,
    - acquérir au cours de l'excitation du transducteur des valeurs prises par au moins une grandeur électrique liée à l'excitation du transducteur pour une pluralité de fréquences de cette bande,
    - analyser les valeurs ainsi acquises pour déterminer une nouvelle fréquence de consigne pour une itération suivante.

    Abstract: The present disclosure provides an aerosol delivery device that may comprise a housing defining an outer wall and further including a power source and a control component. The device also includes a mouthpiece portion that defines an exit aerosol path, a tank portion that includes a reservoir configured to contain a liquid composition, and an atomization assembly configured to vaporize the liquid composition to generate an aerosol. The atomization assembly includes a mesh plate and a vibrating component, wherein the mesh plate and the vibrating component are configured to be separable from each other at a detachable interface. The detachable interface may be located at various locations of the device, including between the mouthpiece portion and the tank portion, within the mouthpiece portion, within the tank portion, within a separable atomization assembly, within a cartridge, within a control unit, or between a cartridge and a control unit.
