Abstract

A positively controlled sound producer for regulated delivery of pressure gas pulses from a pressure gas line (7) to a resonator (1). The sound producer comprises a valve sleeve (9) which is disposed coaxially on the pressure gas line and is rotatably mounted thereon by means of roller bearings (10), said valve sleeve being connected to a prime mover (6) and being provided with openings (14) for cooperating with openings (15) in the pressure gas line when the valve sleeve is rotated for regulating the delivery of pressure gas pulses from the pressure gas line.
