Abstract

The invention relates to an air-driven, low frequency sound generator comprising an open resonator (2) working as a sound emitter and also comprising a feeder unit, for the generation of standing, gas-borne sound waves, which sound waves produce a varying sound pressure inside said resonator. The feeder unit includes a cylinder (5) with one open end facing said open resonator and communicating therewith, further including a piston (4) performing a reciprocating movement inside said cylinder, and also including a surge tank (7), at least partly surrounding said cylinder and connected to a first pressure gas source (9), for feeding pressure gas into the surge tank and further into said cylinder via at least one connection opening (10) arranged in a wall of said cylinder. The sound generator further comprises means (14, 15) for bringing said piston (4) to a stand-still position, in which said connection opening is blocked by the piston, by exerting an additional pressure on the upper end of said piston. The invention also relates to a corresponding method.
