Abstract
A cartridge usable with a portable electronic device for managing an ear bud cable comprises a housing having a hub, a spool and stationary audio contacts fixed with respect to a hub axis. The stationary audio contacts are annular in shape and insulated from each other and from the housing. The stationary audio contacts are spaced equally from each other, and are each placed at fixed distance from the hub axis. The annular stationary audio contacts connect electrically with an auxiliary audio jack and a contact pad for simultaneously connecting the device to more than one audio device. Conductive contacts are placed on a bottom side of the spool, and are spring loaded to maintain continuous electrical contact with the stationary audio contacts.
