1. A retractable earphone comprising:
a housing; a first spring wheel assembly rotatably disposed within the housing; a second spring wheel assembly rotatably disposed within the housing; at least one cable disposed upon the first spring wheel assembly, the at least one cable extensible from within the housing when the first spring wheel assembly is rotated in a first direction and retractable within the housing when the first spring wheel assembly is rotated in a second direction; each of at least one earphone disposed endwise on each of the at least one cable; a connector cable disposed around the second spring wheel assembly, said connector cable extensible from within the housing when the second spring wheel assembly is rotated in a first direction and retractable within the housing when the second spring wheel assembly is rotated in a second direction; wherein movement of the first spring wheel assembly in the first direction unwinds and extends the at least one cable against the action of a spring member and movement of the first spring wheel assembly in the second direction is forced by means of the spring member when the first spring wheel assembly is released whereby the at least one earphone is retracted to a position most proximal the housing; wherein movement of the second spring wheel assembly in the first direction unwinds and extends the connector cable against the action of a spring member and movement of the second spring wheel assembly in the second direction is forced by means of the spring member when the second spring wheel assembly is released whereby an end portion of the connector cable is retracted to a position most proximal the housing; wherein the housing further comprises:
a first end, a second end, a first side, a second side, a top side, a bottom side, and an interior cavity;at least one first aperture disposed at the first end;a second aperture disposed at the second end;wherein each of the at least one cable is disposed through each of the at least one first aperture and the connector cable is disposed through the second aperture; a first push button disposed on the housing top side proximal to the first end, said first push button in operational communication with the first spring wheel assembly; and a second push button disposed on the housing top side proximal to the second end, said second push button in operational communication with the second spring wheel assembly; wherein depression of the first push button releases the first spring wheel assembly to enable rotation in the first and alternately the second direction and depression of the second push button releases the second spring wheel assembly to enable rotation in the first and alternately the second direction, whereby the at least one earphone is alternately extensible and retractable within the housing when the first push button is depressed and the connector cable is alternately extensible and retractable within the housing when the second push button is depressed. |
