A cover for a hand-held device, which has a device body and a speaker, includes a cover body configured for covering a portion the device body and for covering the speaker and a channel for positioning adjacent the device body. The channel is configured to form a sound duct when mounted adjacent the back side of the device body and to be in communication with the speaker when the cover is mounted to the hand-held device for redirecting at least a portion of the sound waves emitted from the speaker to a location remote from the speaker.
