Abstract (en)

[origin: EP3156664A1] An adjustable resonator assembly, comprising a resonator cavity having a neck area with a neck opening configurable to be in fluid communication with a conduit through which a gaseous material can flow, a resonator adjustment structure configured to move from a first position in which the structure closes the neck area when flow of the gaseous material is absent to a second position in which the structure opens the neck area by a predetermined degree in presence of a flow of the gaseous material and a bias mechanism configured to exert a force onto the resonator adjustment structure so as to move the resonator adjustment structure to the first position.
