1. An apparatus for supplying an aerosol in response to an intermittent demand comprising:

  • a first tubular member having first and second opened ends for airflow therethrough;

    an internal substantially tubular member contiguous with an internal surface of said first tubular member, said internal substantially tubular member defining an air chamber within the tubular member, said internal tubular member having closed ends and an aperture near one of the closed ends;

    a planar surface projection internal to the first tubular member and external to the internal tubular member, said planar surface projection oriented to deflect airflow in a first direction through said first tubular member toward said aperture of the internal tubular member;

    a second surface projection upstream in said first direction of said internal tubular member and said aperture, said second surface being oriented to prevent airflow in a second, opposite direction from entering said aperture;

    a window in the first tubular member, said window being arranged to entrain additional airflow through said first tubular member thereby changing the rate of airflow through the first and second opened ends; and

    a second tubular conduit perpendicular to and opening into said first tubular member at a point between said opened ends;

    whereinwhen airflow is effected in said first tubular member, airflow deflected by said planar surface projection through said aperture will generate a vibrational acoustical energy.
