Abstract (en)

[origin: DE19626167C1] The resonator component has distance pieces. The resonator walls (11) are connected to the distance piece (12) by the adhesive layer (14). The work point of the resonator component (10) depends on the free diameter of the resonator walls and the type of fixtures of the collaboratively vibrating surface. The adhesive surface is distributed over the entire inner surface of the resonator walls. Such a layer acts as an anti-resounding coating and enables the vibrations of the resonator walls to be dampened. The resonator walls on their edge areas are provided with at least one counter plate (15) as damping compound system.
