Abstract : The patent relates to a device whereby air is caused to enter a nozzle in which a cylindrical plug is centrally located to form an annular office. 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. One application of this device is to actuate an electric detonator.
