Earbud case with charging system
A case for a pair of earbuds includes a housing having cavities to receive the pair of earbuds and charging circuitry that is configured to initiate charging of the pair of earbuds when an earbud detector detects that the earbuds are inserted within the cavities.
1. A case for an earbud, the case comprising:
a housing having a cavity configured to receive the earbud;
a lid attached to the housing and operable between a closed position where the lid is aligned over the cavity and an open position where the lid is displaced from the cavity;
a lid sensor, at least a portion of which is affixed to the housing, configured to detect when the lid is in the closed position and when the lid is in the open position; and
a charging system including a case battery, and
charging circuitry configured to charge the earbud when the earbud is positioned in the cavity; and
circuitry coupled to the lid sensor and configured to turn off a wireless radio contained within the earbud when the lid sensor detects the lid is moved from the open position to the closed position.
2. The case of claim 1 wherein the housing includes an earbud sensor configured to detect when the earbud is placed in the cavity.
3. The case of claim 2 wherein the charging circuitry is configured to initiate charging of the earbud when the earbud sensor detects the earbud within the cavity.
4. The case of claim 2 wherein the earbud sensor periodically applies a voltage to an earbud charging contact positioned within the cavity to detect the earbud.
5. The case of claim 1 wherein the circuitry is further configured to turn on the wireless radio contained within the earbud when the lid sensor detects the lid is moved from the closed position to the open position.
6. The case of claim 1 wherein the circuitry comprises a processor that generates instructions for the earbud to turn on and turn off the wireless radio contained within the earbud.
7. The case of claim 6 wherein the instructions are sent to the earbud through an electrical connector that couples the earbud to the circuitry.
8. A case for transporting and charging a portable listening device that includes a rechargeable battery and a power contact, the case comprising:
a housing configured to receive the portable listening device;
a lid attached to the housing and operable between a closed position where the lid conceals the listening device within the case and an open position where the lid is displaced from the housing such that a user can remove the listening device from the case;
a lid sensor, at least a portion of which is affixed to the housing, configured to detect when the lid is in the closed position and when the lid is in the open position;
charging circuitry configured to charge the rechargeable battery when the portable listening device is placed in the housing; and
circuitry coupled to the lid sensor and configured to turn off a wireless radio contained within the portable listening device when the lid sensor detects the lid is moved from the open position to the closed position.
9. The case of claim 8 wherein the circuitry is further configured to turn on the wireless radio contained within the portable listening device when the lid sensor detects the lid is moved from the closed position to the open position.
10. The case of claim 8 wherein the circuitry comprises a processor that generates instructions for the portable listening device to turn on and turn off the wireless radio contained within the portable listening device.
11. The case of claim 10 wherein the instructions are sent to the portable listening device through an electrical connector that couples the portable listening device to the circuitry.
12. The case of claim 8 wherein the housing includes a portable listening device sensor configured to detect when the portable listening device is placed in the cavity.
13. The case of claim 12 wherein the portable listening device sensor periodically applies a voltage to a portable listening device charging contact positioned within the cavity to detect the portable listening device.
14. The case of claim 12 wherein the charging circuitry is configured to initiate charging of the portable listening device when the portable listening device sensor detects the portable listening device within the cavity.
15. A case for an earbud, the case comprising:
a housing having a cavity configured to receive the earbud;
a lid attached to the housing and operable between a closed position where the lid is aligned over the cavity and an open position where the lid is displaced from the cavity;
a lid sensor, at least a portion of which is affixed to the housing, configured to detect when the lid is in the closed position and when the lid is in the open position; and
a charging system including a case battery and charging circuitry configured to charge the earbud when the earbud is positioned in the cavity; and
circuitry coupled to the lid sensor and configured to turn on a wireless radio contained within the earbud when the lid sensor detects the lid is moved from the closed position to the open position.
16. The case of claim 15 wherein the circuitry is further configured to turn off the wireless radio contained within the of earbud when the lid sensor detects the lid is moved from the open position to the closed position.
17. The case of claim 15 wherein the circuitry comprises a processor that generates instructions for the earbud to turn on and turn off the wireless radio contained within the earbud.
18. The case of claim 17 wherein the instructions are sent to the earbud through an electrical connector that couples the earbud to the circuitry.
19. The case of claim 15 wherein the housing includes an earbud sensor configured to detect when the earbud is placed in the cavity.
20. The case of claim 19 wherein the charging circuitry is configured to initiate charging of the earbud when the earbud sensor detects the earbud within the cavity.
