Embodiments describe a hinge for a case that stores wireless listening devices, including: a first shaft forming a first pivot point for the hinge; a second shaft forming a second pivot point for the hinge, the first shaft and the second shaft defining a conversion axis; a piston rod having a first end and a second end, the first end coupled to the second shaft and a second end opposite from the first end coupled to a stopper; a piston guide slidably coupled to the piston rod between the first end and the second end of the piston rod; a third shaft forming a third pivot point for the piston guide, the third shaft allowing the piston guide to rotate and maintain concentric alignment with the piston guide; and a spring positioned between the second shaft and the piston guide and wound around the piston rod.
1. A hinge for a case that stores wireless listening devices, comprising:
a first shaft forming a first pivot point for the hinge;
a second shaft forming a second pivot point for the hinge and being positioned a distance away from the first shaft, the first shaft and the second shaft defining a conversion axis intersecting centers of both the first shaft and the second shaft;
a piston rod having a first end and a second end opposite from the first end, the first end being coupled to the second shaft and the second end being coupled to a stopper;
a piston guide slidably coupled to the piston rod between the first end and the second end of the piston rod;
a third shaft forming a third pivot point for the piston guide, the third shaft allowing the piston guide to rotate and maintain concentric alignment with the piston guide; and
a spring positioned between the second shaft and the piston guide and wound around the piston rod, the spring generating a force along an axis of the piston rod.
2. The hinge of claim 1 , wherein the force moves the hinge into a first state or a second state depending on the angle between the axis and the conversion axis.
3. The hinge of claim 2 , wherein the conversion axis defines an angle at which the hinge moves between the first state and the second state.
4. The hinge of claim 3 , wherein the spring generates more torsional force as the axis is angled farther away from the conversion axis.
5. The hinge of claim 2 , wherein the hinge is implemented in a lid for a case including a body from which the lid opens and closes.
6. The hinge of claim 5 , wherein the first state is a closed state in which the lid is positioned parallel to a horizontal dimension, and the second state is an opened state in which the lid is positioned at an angle to the horizontal dimension.
7. The hinge of claim 5 , wherein the stopper makes contact with a seat formed by the lid when positioned in an opened state.
8. The hinge of claim 1 , wherein the piston guide comprises an inner diameter formed as a tube through which the piston rod is positioned.
9. The hinge of claim 1 , wherein the stopper includes an annular flange region oriented perpendicular to an outer surface of the piston rod.
10. A case for a wireless listening device, comprising:
a lid movable between an opened position and a closed position;
a hinge coupled to the lid to allow the lid to move between the opened position and the closed position, the lid comprising:
a first shaft forming a first pivot point for the hinge;
a second shaft forming a second pivot point for the hinge and being positioned a distance away from the first shaft, the first shaft and the second shaft defining a conversion axis intersecting centers of both the first shaft and the second shaft;
a piston rod having a first end and a second end opposite from the first end, the first end being coupled to the second shaft and the second end being coupled to a stopper;
a piston guide slidably coupled to the piston rod between the first end and the second end of the piston rod;
a third shaft forming a third pivot point for the piston guide, the third shaft allowing the piston guide to rotate and maintain concentric alignment with the piston guide; and
a spring positioned between the second shaft and the piston guide and wound around the piston rod, the spring generating a force along an axis of the piston rod; and
a body coupled to the lid by the hinge.
11. The case of claim 10 , wherein the case further comprises an inner frame comprising a curved surface for receiving the wireless listening devices.
12. The case of claim 10 , wherein the spring generates force to move the hinge into a first state or a second state depending on the angle between the axis and the conversion axis.
13. The case of claim 12 , wherein the conversion axis defines an angle at which the hinge moves between the first state and the second state.
14. The case of claim 13 , wherein the spring generates more torsional force as the axis is angled farther away from the conversion axis.
15. A wireless listening device system, comprising:
a wireless listening device comprising:
a housing comprising an acoustic opening and a nozzle disposed around the acoustic opening, the acoustic opening being formed in an outer structure of the housing and configured to allow sound to exit out of the outer structure; and
a first communication system disposed within the housing and configured to send and receive data; and
a case allowing storage of the wireless listening device, the case comprising:
a lid movable between an opened position and a closed position;
a hinge coupled to the lid to allow the lid to move between the opened position and the closed position, the lid comprising:
a first shaft forming a first pivot point for the hinge;
a second shaft forming a second pivot point for the hinge and being positioned a distance away from the first shaft, the first shaft and the second shaft defining a conversion axis intersecting centers of both the first shaft and the second shaft;
a piston rod having a first end and a second end opposite from the first end, the first end being coupled to the second shaft and the second end being coupled to a stopper;
a piston guide slidably coupled to the piston rod between the first end and the second end of the piston rod;
a third shaft forming a third pivot point for the piston guide, the third shaft allowing the piston guide to rotate and maintain concentric alignment with the piston guide; and
a spring positioned between the second shaft and the piston guide and wound around the piston rod, the spring generating a force along an axis of the piston rod; and
a body coupled to the lid by the hinge, the body comprising a second communication system configured to send and receive data with the first communication system of the wireless listening device.
16. The wireless listening device system of claim 15 , wherein the spring generates force to move the hinge into a first state or a second state depending on the angle between the axis and the conversion axis.
