FLUIDIC GENERATOR

Air is caused to enter a nozzle in which a cylindrical plug is centrally located to form an annular orifice. The air discharging from the annular orifice impinges directly on the edge of a resonating cavity producing a multiple frequency edgetone. The column of air in the resonating cavity is thereby caused to vibrate at a frequency determined by the depth of the cavity. The changes in pressure within the resonating cavity cause a diaphragm forming an end of the cavity to pulsate inwardly and outwardly. A rod is attached to the diaphragm, and this rod transmits the vibrations of the diaphragm to a metallic reed which will then oscillate between a pair of magnetic pole pieces. The oscillations of the reed will induce an electro-motive force into a coil. The electromotive force induced in the coil may be made available to provide energy to operate an external electrical circuit.
