Abstract: Disclosed is a device that in many embodiments may be comprised of what is commonly described as a “case” in the portable electronic device industry, which is largely a cavity which envelopes the portable electronic device. This case may be one solid piece, or be multiple pieces that then assemble around the portable electronic device to protect and/or decorate the device. In one embodiment, the case's functional purpose is serving as a wallet, with a slot to store items such as credit or identification cards. In a preferred embodiment the case component may then be comprised of one or more sound guides which are designed to control and direct sound from its origin and emit the sound towards the front or the face of the case. This origin is typically one or more speakers, and the guides may additionally serve to alter or enhance the acoustics of the produced sound.
