Abstract:
An acoustic generator of pressure pulsations includes a cylindrical waveguide which is caused to vibrate at a low amplitude by an electromechanical transducer. The vibration of the cylindrical waveguide creates low amplitude pressure pulsations in an acoustic chamber containing stationary pressure fluid. A mechanical amplifier, which is part of the acoustic chamber, amplifies the low amplitude pressure pulsations generated by the cylindrical waveguide.
