Abstract
A multi-chamber resonator box for a vehicle air intake system, wherein the resonator includes a Helmholtz, an expansion chamber, an annular, and a perforated style resonator to militate against the emission of noise energy caused by intake air.
Claims13
A multi-chamber air resonator comprising:
- a duct having an inlet and an outlet;
- a main body surrounding at least a portion of said duct;
- an expansion chamber type resonator, an annular type resonator, a Helmholtz type resonator, and a perforated type resonator disposed in said main body, said resonators in communication with said duct to attenuate noise travelling through said duct.
A multi-chamber air resonator comprising:
- a hollow tray section having an air inlet;
- an inner cover section adapted to be inserted into said tray section, said inner cover including a hollow tube having an inlet and an outlet, the inlet of the tube of the inner cover section adapted to be in fluid communication with the air inlet of said tray section, said inner cover section including at least one of a Helmholtz type resonator and a perforated type resonator in communication with the hollow portion of the tube of said inner cover section;
- and
- a cover section including a hollow tube having an inlet and an outlet, the inlet of the tube of said cover section adapted to be in fluid communication with the outlet of the tube of said inner cover section, said cover section including an annular type resonator therein for attenuating low frequency noise travelling in the tube of said cover section.
