ACOUSTIC RADIATOR ASSEMBLY FOR ACTIVE SOUND DAMPERS

The invention relates to an acoustic radiator assembly having at least two acoustic radiators (1), which each have a sheet material having a front side and a back side, which sheet material is supported in such a way that the sheet material can vibrate. The front sides face a region (5) in which sou...

Beschreibung
Zusammenfassung:	The invention relates to an acoustic radiator assembly having at least two acoustic radiators (1), which each have a sheet material having a front side and a back side, which sheet material is supported in such a way that the sheet material can vibrate. The front sides face a region (5) in which sound (8) should be damped, and the back sides of the sheet materials, which sheet materials are supported in such as way that the sheet materials can vibrate, face a common volume (6). The acoustic radiator assembly is characterized in that a control unit (3) is present, which is designed in such a way that the sheet materials, which are supported in such as way that the sheet materials can vibrate, can be excited so as to cause vibrations having a phase difference among each other, in particular having a phase difference in the range of approximately 90° to approximately 180°.
