Patent number: 7104463Abstract: An aerosol generator comprises a vibratable member having a front, a rear, an outer periphery and a plurality of apertures extending between the front and the rear. A support element is disposed about the outer periphery of the vibratable member, and a vibratable element is coupled to the support element. The vibratable element is configured to vibrate the vibratable member at ultrasonic frequencies. An isolating structure is coupled to the support element and is configured to couple the aerosol generator to a support structure. The isolating structure has a mechanical vibrational impedance that is sufficient to substantially vibrationally isolate the aerosol generator from the support structure.Type: GrantFiled: October 6, 2005Date of Patent: September 12, 2006Assignee: Aerogen, Inc.Inventors: Craig M. Litherland, Joseph Loeffler, Joe Maxwell

Publication number: 20020162551Abstract: 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.Type: ApplicationFiled: May 2, 2001Publication date: November 7, 2002Inventor: Craig M.
