(54) Title
Wireless pairing of earbuds and case
(57) Abstract

A case for a pair of wireless earbuds includes a lid and a lid sensor configured to generate a detect signal when the lid is moved from a closed position to an open position. The case further includes circuitry configured to, in response to receiving the detect signal, send a signal to the wireless earbuds to turn them on and to initiate a pairing sequence between the wireless earbuds and an electronic device.

Claims (19)

  1. A case for a portable listening device that includes a wireless radio, the case comprising: a housing having a receiving area for the portable listening device; a lid attached to the housing and operable between a closed position where the lid covers the portable listening device when positioned in the receiving area and an open position that allows a user to remove the portable listening device from the receiving area; an input device including circuitry configured to detect a user interaction with the case and to generate a signal in response to the detected user interaction; and a processor coupled to the input device, the processor configured to send an instruction to the portable listening device to initiate wireless pairing of the portable listening device to a host electronic device in response to the generated signal.
  2. The case of claim 1 wherein the user interaction is a user moving the lid from the closed position to the open position.
  3. The case of claim 1 wherein the instruction is sent to the portable listening device through an electrical connector that couples the portable listening device to the case.
  4. The case of claim 3 wherein the electrical connector is disposed in the receiving area of the case and the portable listening device is coupled to the electrical connector when the portable listening device is placed within the receiving area of the case.
  5. The case of claim 1 wherein the instruction is sent to the portable listening device using wireless communication.
  6. The case of claim 1 wherein the user interaction is a user depressing a button.
  7. The case of claim 1 wherein the wireless pairing of the portable listening device to the host electronic device is executed automatically in response to the portable listening device receiving the instruction.
  8. The case of claim 1 further comprising a memory that stores a connection history for multiple host electronic devices enabling automatic pairing without requiring input from a user after sending the instruction.
  9. The case of claim 8 wherein the memory stores one or more Bluetooth link keys.
  10. A case for a portable listening device, the case comprising: a housing having a receiving area for the portable listening device; a lid attached to the housing and operable between a closed position where the lid covers the portable listening device when positioned within the receiving area and an open position that allows a user to remove the portable listening device from the receiving area; a lid sensor configured to generate a signal when the lid is moved from the closed position to the open position; and a processor coupled to lid sensor and configured to send an instruction to the portable listening device to initiate wireless pairing of the portable listening device to a host electronic device in response to detecting the generated signal.
  11. The case of claim 10 wherein the instruction is sent to the portable listening device through an electrical connector that couples the portable listening device to the case.
  12. The case of claim 11 wherein the electrical connector is disposed in the receiving area of the case and the portable listening device is coupled to the electrical connector when the portable listening device is placed within the receiving area of the case.
  13. The case of claim 10 wherein the instruction is sent to the portable listening device using wireless communication.
  14. The case of claim 10 wherein the case includes a button that is depressible by a user and is coupled to the processor.
  15. The case of claim 10 wherein the wireless pairing of the portable listening device to the host electronic device is executed automatically in response to the portable listening device receiving the instruction.
  16. The case of claim 10 further comprising a memory that stores a connection history for multiple host electronic devices enabling automatic pairing without requiring input from a user after sending the instruction.
  17. The case of claim 16 wherein the memory stores one or more Bluetooth link keys.
  18. The case of claim 10 wherein when the processor detects the generated signal it first determines that the portable listening device has not been paired before and in response sends the instruction to the portable listening device to initiate wireless pairing.
  19. The case of claim 1 wherein in response to the generated signal, the processor first determines that the portable listening device has not been paired before and in response sends the instruction to the portable listening device to initiate wireless pairing.

Description

This application is related to the following commonly assigned U.S. nonprovisional patent applications:

The described embodiments relate generally to portable listening devices such as earbuds and other types of headphones, and to cases for storing and charging such devices.

Portable listening devices can be used with a wide variety of electronic devices such as portable media players, smart phones, tablet computers, laptop computers, stereo systems and other types of devices. Portable listening devices have historically included one or more small speakers configured to be place on, in, or near a user's ear, structural components that hold the speakers in place, and a cable that electrically connects the portable listening device to an audio source. Other portable listening devices can be wireless devices that do not include a cable and instead, wirelessly receive a stream of audio data from a wireless audio source.

While wireless portable listening devices have many advantages over wired devices, they also have some potential drawbacks. For example, wireless portable listening devices, typically require one or more batteries, such as a rechargeable battery, that provides power to the wireless communication circuitry and other components of the device. Single use batteries need to be replaced when their charge is depleted while rechargeable batteries need to be periodically recharged. Also, if the portable wireless listening device is a pair of wireless earbuds, the earbuds can be relatively small and easy to lose when not in use.

  "description_excerpt": "This application is related to the following commonly assigned U.S. nonprovisional patent applications:\n\nThe described embodiments relate generally to portable listening devices such as earbuds and other types of headphones, and to cases for storing and charging such devices.\n\nPortable listening devices can be used with a wide variety of electronic devices such as portable media players, smart phones, tablet computers, laptop computers, stereo systems and other types of devices. Portable listening devices have historically included one or more small speakers configured to be place on, in, or near a user's ear, structural components that hold the speakers in place, and a cable that electrically connects the portable listening device to an audio source. Other portable listening devices can be wireless devices that do not include a cable and instead, wirelessly receive a stream of audio data from a wireless audio source.\n\nWhile wireless portable listening devices have many advantages over wired devices, they also have some potential drawbacks. For example, wireless portable listening devices, typically require one or more batteries, such as a rechargeable battery, that provides power to the wireless communication circuitry and other components of the device. Single use batteries need to be replaced when their charge is depleted while rechargeable batteries need to be periodically recharged. Also, if the portable wireless listening device is a pair of wireless earbuds, the earbuds can be relatively small and easy to lose when not in use.",
