The aerosol generator includes a vibratable membrane having a front face and a rear face, and a vibratable element used to vibrate the membrane. Further, the housing includes an opening that is adapted to receive a unit dosage of the liquid from the container. The opening provides a liquid path to the rear face of the vibratable membrane.
