An aerosol generator (10) comprises a vibratable member (12) having a front, a rear (14), an outer periphery (16) and a plurality of apertures extending between the front and the rear. A support element is disposed about the outer periphery (16) of the vibratable member (12), and a vibratable element is configured to vibrate the vibratable member (12) at ultrasonic frequencies. An isolating structure (18) is coupled to the support element and is configured to couple the aerosol generator (10) to a support structure. The isolating structure (18) has a mechanical vibrational impedence that is sufficient to substantially vibrationally isolate the aerosol generator (10) from the support structure.
L'invention concerne un générateur d'aérosols (10) qui comprend une unité vibrante (12) constituée d'une partie avant, d'une partie arrière (14), d'une périphérie extérieure (16) et d'une pluralité d'ouvertures qui s'étendent entre l'avant et l'arrière. Un élément de support est disposé autour de la périphérie extérieure (16) de l'unité vibrante (12) et un élément vibrant est conçu pour faire vibrer l'unité vibrante (12) à des fréquences ultrasonores. Une structure isolante (18) couplée à l'élément de support est conçue pour coupler le générateur d'aérosols (10) à une structure de support. Cette structure isolante (18) comporte une impédance vibratoire mécanique suffisante pour isoler de manière sensiblement vibratoire le générateur d'aérosols (10) de la structure de support.
