Abstract: An acoustic enclosure includes a housing at least partially defining an acoustic chamber for an acoustic radiator. The housing further defines an acoustic opening from the acoustic chamber to a surrounding environment. The acoustic enclosure also has a first acoustic resonator and a second acoustic resonator. The first acoustic resonator and the second acoustic resonator are acoustically coupled with the acoustic chamber in parallel relative to each other. Each of the first acoustic resonator and the second acoustic resonator modifies a frequency response of the acoustic chamber. Loudspeakers can include such an enclosure acoustically excited or driven by an electro-acoustic transducer. As well, an electronic device can include such a loudspeaker.
