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.

Abstract: A retractable ear bud module. The ear bud module is has a housing for holding an ear bud cable, an ear bud cable moveably mounted in the housing, the ear bud cable having a free end with at least one ear bud and a fixed end. A circuit board including a wireless receiver mounts in the housing for communicating with the electronic device. The wireless receiver electronically connects with the ear bud cable to transfer audio signals from the electronic device to the ear bud. A retraction mechanism mounts in the housing to retract and dispense the ear bud cable. The retraction mechanism includes a rotatable spool mounted in the housing, a spring recessed centrally within the spool, and an annular retainer circumscribing the spool to align the ear bud cable on the spool.

Abstract: 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.

Abstract: A case for holding an audio device having a female audio jack. The case has a removable cover including a male audio jack for electronically connecting the cover to the female audio jack of the audio device. The cartridge includes a spool and houses an ear bud cable. The ear bud cable has a first end with at least one ear bud, and a second end attached to the spool. The cartridge has a rotatable spool for selectively retracting and dispensing the ear bud cable. The spool electronically connects with the male audio jack to enable audio communication between the audio device and the ear bud. In one embodiment, the spool electronically connects with the male audio jack via a jumper wire. In another embodiment, the spool electronically connects with the male audio jack via an electrical contact pad integrated into the case.

Abstract: A cartridge for managing ear bud cables includes a housing, a hub, a spool and an ear bud cable. The housing has an input jack that is electronically connectable to an audio-source. The hub is fixed in the housing defines a stationary contact surface electrically connected with the input jack. The rotatably mounts with respect to the hub and has moveable audio contacts for continuously contacting the stationary contact surface during rotation of the spool and while the spool is stationary. 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.
