Abstract

Disclosed is a portable audio device and a quick-disconnect passive acoustic cover. The portable audio device includes a housing and a speaker supported by the housing that have a first system frequency response. The speaker of the portable audio device has a first side and a second side associated with a first audio port and a second audio port, associated with a first acoustic load and a second acoustic load respectively. The housing is configured to removably receive the cover which is configured to redefine at least one of the first acoustic load and the second acoustic load to replace the first system frequency response with a second system frequency response. The cover provides one or more additional surrounding structures, which replace the inherent frequency response with an improved frequency response. Different embodiments of the disclosed cover provide a plurality of sound quality enhancement options to a user.
