Filter system comprising filter housing, replaceable filter element, and resonator structure

A filter system comprising:

• a filter housing enclosing an interior space;
• a filter element exchangeably arranged in the interior space;
• a resonator structure arranged in the interior space, wherein the resonator structure comprises resonator housing elements forming a closed resonator housing, wherein the resonator housing encloses a cavity;
• a partition dividing the cavity into a first chamber and into a second chamber, wherein the partition comprises at least one passage through which the first chamber and the second chamber are acoustically coupled;
• wherein the filter housing comprises a first housing part which comprises one of the resonator housing elements;
• wherein the filter element comprises another one of the resonator housing elements;
• wherein the filter element comprises a filter bellows;
• wherein the filter element comprises a cutout, wherein the cutout penetrates the filter bellows and extends from an inflow side of the filter bellows all the way to an outflow side of the filter bellows;
• wherein the cutout is a first resonator housing receptacle, wherein at least one of the resonator housing elements is arranged in the cutout.
