<p>A sound emitter driven by pressurized gas and having a resonator horn (15). According to the invention, the resonator horn is connected to one outlet branch (12) of a fluidistor (10) while the other outlet branch (13) is connected to a tuned member (16) having the same acoustic input impedance as the resonator horn. By the fluidistor being brought to oscillate, the emission of the pressurized gas from the resonator horn is controlled while generating sound oscillations substantially at a predetermined frequency.</p> |
