Summary:An aerosol generator comprises a vibratable element and a support member that is coupled to the vibratable element. The support member is cymbal-shaped and has a concave surface and a central opening, and the concave surface faces the vibratable element. A vibratable member is disposed across the central opening and has a plurality of apertures. In this way, liquid that is applied to a rear surface of the vibratable member is ejected from the front surface as an atomized spray upon vibration of the vibratable element.
