Abstract

A case for a pair of earbuds includes an insert positioned within the case and configured to receive the pair of earbuds. A contact assembly is attached to the insert and includes electrical contacts that extend into the inserts such that they make electrical contact with an earbud connector disposed on each of the pair of earbuds.

Claims

1. A case for a pair of earbuds, each earbud having an ear portion and a stem portion with an electrical connector disposed at a distal end of the stem portion, the case comprising:

a housing;

an insert positioned within the housing, the insert having first and second cavities sized and shaped to accommodate first and second earbuds, respectively, each of the first and second cavities having a receiving opening to receive an earbud into the cavity and a contact opening opposite the receiving opening; and

a contact assembly attached to the insert, the contact assembly comprising a first pair of electrical contacts extending into the first cavity and a second pair of electrical contacts extending into the second cavity, the first and second pairs of electrical contacts configured to make electrical contact with the electrical connector disposed at the distal end of the first and second earbuds, respectively, through the contact opening.

2. The case of claim 1 wherein the insert comprises a first shell and a second shell joined together, the first shell including the first cavity and the second shell including the second cavity.

3. The case of claim 2 further comprising a collar adhered to a top of the contact assembly and to a periphery of a distal end of each of the first and the second shells.

4. The case of claim 1 wherein the first and second pairs of electrical contacts each have arcuate portions that are positioned by a contact carrier to couple to the electrical connector disposed at the distal end of the first and second earbuds.

5. The case of claim 4 wherein the contact assembly includes a cavity formed below the arcuate portions.

6. The case of claim 5 wherein the cavity has a depth that extends below the arcuate portions and is greater than one half of a diameter of the cavity.

7. The case of claim 4 wherein the arcuate portions deflect outwardly when the pair of earbuds are received within the first and second cavities.

8. The case of claim 1 wherein the contact assembly is formed from a dielectric material.

9. The case of claim 1 wherein a liquid-tight seal is formed between the contact assembly and the insert.

10. An electrical connector assembly for an earbud charging system, the electrical connector assembly configured to receive an earbud having an ear portion and a stem portion with an earbud connector disposed at a distal end of the stem portion, the electrical connector assembly comprising:

a shell having a receiving opening to receive the earbud in a stem-first orientation, a distal end opposite the receiving opening, and a contact opening proximate the distal end that opens to the receiving opening;

a contact carrier formed from a dielectric material and coupled to the distal end of the shell, the contact carrier having a cavity sized to receive the distal end of the shell and a pair of contact receiving slots; and

a pair of deflectable electrical contacts disposed within the pair of contact receiving slots, each deflectable electrical contact having a contact portion that extends through the contact opening of the shell.

11. The electrical connector assembly of claim 10 wherein the distal end of the shell is disposed within the cavity and adhered to the contact carrier.

12. The electrical connector assembly of claim 11 wherein the shell has a pair of clearance slots disposed in the distal end such that when the distal end of the shell is disposed within the cavity the contact portions of the pair of deflectable electrical contacts protrude through the slots.

13. The electrical connector assembly of claim 10 further comprising a collar adhered to a top of the contact carrier and to a periphery of the shell.

14. The electrical connector assembly of claim 10 wherein the contact portions of the deflectable electrical contacts are positioned to interfere with the earbud connector when the earbud is received by the electrical connector assembly.

15. The electrical connector assembly of claim 14 wherein the cavity in the contact carrier has a depth that extends a distance greater than one half of a diameter of the cavity below arcuate portions of the deflectable electrical contacts.

16. The electrical connector assembly of claim 10 further comprising a second shell, a second contact carrier and a second pair of deflectable electrical contacts such that the connector assembly can receive a pair of earbuds.

17. A case for a pair of earbuds, each earbud having an ear interface portion and a stem portion with an electrical connector disposed at a distal end of the stem portion, the case comprising:

a housing;

an insert positioned within the housing, the insert having first and second earbud receiving cavities sized and shaped to accommodate first and second earbuds, respectively, each of the first and second receiving cavities having a receiving opening to receive an earbud into the receiving cavity in a stem-first orientation, a contact opening at an opposite end of the receiving opening;

a contact carrier formed from a dielectric material and coupled to the insert, the contact carrier having first and second pairs of contact receiving slots disposed at a contact interface region and a debris recess configured to capture debris positioned between the first pair of contact receiving slots and a second debris recess disposed below the contact interface region and sized and shaped to capture debris;

a first pair of deflectable electrical contacts disposed within first pair of contact receiving slots, each of the first pair of deflectable electrical contacts having a contact portion that extends into the first receiving cavity in the contact interface region; and

a second pair of deflectable electrical contacts disposed within second pair of contact receiving slots, each of the second pair of deflectable electrical contacts having a contact portion that extends into the second receiving cavity in the contact interface region.

18. The case of claim 17 wherein the debris recess includes a first debris recess positioned between the first pair of contact receiving slots and a second debris recess positioned between the second pair of contact receiving slots.

19. The case of claim 17 wherein each of the first and second earbud receiving cavities includes an elongated tube portion sized and shaped to accommodate the stem portion of an earbud and a larger earbud receiving opening sized and shaped to at least partially accommodate the ear interface portion.

20. The case of claim 17 wherein the contact portion of each of the deflectable electrical contacts has a curved profile.
