A cartridge for managing ear bud cables includes a housing, a hub, a spool with a moveable audio contact and an ear bud cable. The housing has an input jack that is electronically connectable to an audio-source. The hub defines a stationary contact surface electrically connected with the input jack.
A cartridge for managing ear bud cables includes a housing, a hub, a spool with a moveable audio contact and an ear bud cable. The housing has an input jack that is electronically connectable to an audio-source. The hub defines a stationary contact surface electrically connected with the input jack. The ear bud cable wraps at least partially around the spool, the ear bud cable has a first end and a second end, the first end being electrically connected with the moveable audio contact of the spool and the second end being electrically connected with at least one ear bud. Rotation of the spool selectively retracts and dispenses the ear bud cables while enabling continuous audio communication between the at least one ear bud and the audio source.

1. A cartridge for managing an ear bud cable, comprising: a housing having an input jack that is electronically connectable to an audio-source;a hub fixed in the housing, the hub has stationary audio contacts extending from the hub to create a stationary contact surface, the stationary audio contacts being electrically connected with the input jack;a spool rotatably mounted on the hub, the spool having moveable audio contacts for continuously contacting the stationary contact surface during rotation of the spool;an ear bud cable wrapped at least partially around the spool, the ear bud cable has a first end and a second end, the first end being electrically connected with the moveable audio contact of the spool and the second end being electrically connected with at least one ear bud; androtation of the spool selectively retracts and dispenses the ear bud cables while enabling continuous communication between the at least one ear bud and the audio source, wherein the stationary contact surface includes at least one conductive contact circumscribing the hub. 2. A cartridge as set forth in claim 1, wherein the stationary contact surface includes several metallic contacts circumscribing the hub, the hub includes circumferential ridges which separate the several metallic contacts. 3. A cartridge as set forth in claim 2, wherein the housing has an output jack integrated with the input jack and the ear bud cables include a microphone for communicating voice via the cartridge. 4. A cartridge as set forth in claim 3, wherein the ear bud cable is flat, having a height and a width, wherein the width is more than twice the height. 5. A cartridge as set forth in claim 3, wherein the ear bud cable is flat, having a height and a width, wherein the width is more than twice the height, the ear bud cable includes two ear buds and a microphone. 6. A cartridge for managing an ear bud cable, comprising: a housing having an input jack that is electronically connectable to an audio-source;a hub fixed in the housing, the hub has stationary audio contacts extending from the hub to create a stationary contact surface and to electrically connect the stationary audio contacts with the input jack;a spool rotatably mounted on the hub, the spool having moveable audio contacts for continuously contacting the stationary contact surface during rotation of the spool, the spool having an upper gear and a lower gear, and a cable track defined between the upper gear and the lower gear;a power gear mounted in the housing and being connectable in operable engagement with both the upper gear and the lower gear of the spool; andan ear bud cable wrapped at least partially around the spool in the cable track, the ear bud cable has a first end and a second end, the first end being electrically connected with the moveable audio contact of the spool and the second end with at least one ear bud,whereby rotation of the spool selectively retracts and dispenses the ear bud cable while maintaining communication between the at least one ear bud and the audio source. 7. A cartridge as set forth in claim 6 further comprising a power spring mounted in the housing in contact with the power gear to rotate the power gear and the spool. 8. A cartridge as set forth in claim 6 further comprising a power spring mounted in the housing in contact with the power gear to rotate the power gear and the spool, the power spring having a spiral shape and designed to maintain a relatively consistent torque on the power gear. 9. A cartridge as set forth in claim 6 further comprising a rotary damper attached within the housing and connected in operable engagement with spool to regulate rotational velocity of the spool. 10. A cartridge as set forth in claim 6 further comprising a rotary damper attached within the housing, the rotary damper having gear teeth connected in operable engagement with the upper gear and the lower gear of the spool to regulate rotational velocity of the spool. 11. A cartridge as set forth in claim 6 further comprising a cable guide mounted on the housing, the cable guide receives the ear bud cable to guide the ear bud cable into and out from the cartridge. 12. A cartridge as set forth in claim 6, wherein the power gear, the upper gear and the lower gear have gear teeth that mesh. 13. A cartridge for managing an ear bud cable, comprising: a housing having an input jack that is electrically connectable to an audio-source;a hub fixed in the housing, the hub defines a stationary contact surface that circumscribes the hub and electrically connects with the input jack;a spool rotatably mounted with respect to the hub, the spool having moveable audio contacts for continuously contacting the stationary contact surface during rotation of the spool; andan ear bud cable wrapped at least partially around the spool, the ear bud cable has a first end and a second end, the first end being electrically connected with the moveable audio contact of the spool and the second end being electrically connected with at least one ear bud, whereby rotation of the spool selectively retracts and dispenses the ear bud cables while enabling continuous communication between the at least one ear bud and the audio source. 14. A cartridge as set forth in claim 13, wherein the hub defines a hollow center for receiving a portion of the spool, the stationary contact surface includes at least one contact inscribed within the hub for continuously contacting the moveable audio contacts. 15. A cartridge as set forth in claim 13, wherein the hub defines a hollow center for receiving a portion of the spool, the stationary contact surface includes contacts having a ring shape and ridges having a ring shape for separating the contacts, the contacts and ridges being inscribed within the hub for continuously contacting the moveable audio contacts. 16. A cartridge as set forth in claim 13, wherein the stationary contact surface includes contacts circumscribing the hub, the hub includes circumferential ridges which separate the contacts.
