Cartridge for managing ear buds
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.
