Abstract (en)
A portable audio system includes a housing defining a common acoustic cavity a woofer disposed at a first end of the housing in the common acoustic cavity and a tweeter disposed at a second end of the housing, opposite to the first end, in the common acoustic cavity facing the woofer. A waveguide is disposed in the common acoustic cavity between the woofer and the tweeter to separate the woofer and the tweeter. The waveguide disperses and distributes sound waves generated by the woofer and tweeter.
