    摘要: The invention relates to a vibration damper (1) configured to be provided on a low frequency sound generator, which comprises a feeder unit (2) with a positive feedback system regulated by a reciprocating spring loaded piston (3) and a resonator tube (4). The vibration damper (1) may be positioned outside the resonator tube (4). The vibration damper (1) comprises a first flange (5) connected to the resonator tube (4), a number of springs (6), a second flange (7) and a number of weights (8).
