Abstract
The present disclosure relates to an acoustic baffle (2) for attenuating sound waves generated by an acoustic source (3). The acoustic baffle (2) is made up of one or more cells (8). The cells (8) each have opposing first and second walls (11, 12) defining at least one resonator chamber (9) for attenuating sound waves generated by the acoustic source (3). The first wall (11) has an inlet aperture (16) for ingress of sound waves generated by the acoustic source into the resonator chamber (9); and the second wall (12) has an outlet aperture (17) for egress of attenuated sound waves from the resonator chamber (9). The present disclosure also relates to an audio transducer assembly (3) including an acoustic baffle (2). Furthermore, the present disclosure relates to a vehicle including an acoustic baffle (2).
Claims24
An acoustic baffle for attenuating sound waves generated by an acoustic source, the acoustic baffle comprising:
- a plurality of cells, wherein each cell comprises opposing first and second walls that define at least one resonator chamber for attenuating sound waves generated by the acoustic source, wherein the first wall comprises an inlet aperture for ingress of sound waves generated by the acoustic source into the at least one resonator chamber, and wherein the second wall comprises an outlet aperture for egress of attenuated sound waves from the at least one resonator chamber,
- wherein the plurality of cells are arranged concentrically about a central axis of the acoustic baffle, and
- wherein an internal volume of the at least one resonator chamber increases with radial distance of the at least one resonator chamber from the central axis.
