Abstract
An audio device with an acoustic radiator that emits acoustic radiation from a first side, a housing that defines an acoustic cavity that receives the acoustic radiation emitted from the first side of the acoustic radiator, and first and second sound-emitting outlets in the housing and acoustically coupled to the acoustic cavity such that the outlets emit sound from the acoustic cavity. The second sound-emitting outlet has a greater equivalent acoustic impedance than the first sound-emitting outlet.
