ABSTRACT:
An aerosol dispensing apparatus comprises a housing which includes a top l having a sharp edged orifice and a speaker assembly mounted on a bottom portion of the housing. A sawtooth waveform generator generates and then provides a sawtooth waveform signal which includes a jitter component to the speaker assembly which drives a flexible diaphragm resulting in a reciprocating motion of the flexible diaphragm. The ramp portion of sawtooth waveform signal retracts the flexible diaphragm in a rearward direction, while the approximately vertical portion of the signal causes an abrupt forward movement of the flexible diaphragm. The inner portion of the housing forms a chamber which contains a medication. The jitter component of the sawtooth waveform signal fluidizes the medication suspending the medication in air within the chamber to form a vaporized medication. Each cycle of the sawtooth waveform signal generates one ring vortex of a train of ring vortices with the ring vortex being generated during the vertical portion of the signal when the abrupt forward movement of the flexible diaphragm occurs.
