Abstract
A cartridge for managing an ear bud cable includes a housing having an input jack that is electronically connectable to an audio-source and a hub electrically connected with the input jack. A spool rotatably mounts on, and is electrically connected with, the hub. A power gear mounts in the housing and in contact with the spool for rotating the spool. The power gear defines a recessed interior. An ear bud cable wraps at least partially around the spool. A power gear spring mounts within the recessed interior of the power gear to minimize the size and, particularly, the thickness of the cartridge. In an alternate embodiment, the spool includes a recessed portion and a spool power spring mounts within the recessed portion of the hub. In yet another embodiment, the spool and the power gear both have recessed portions that hold a power spring.
