Abstract

One or more embodiments set forth include a personal aural device that includes an expandable eartip. The expandable eartip has a contracted state and an expanded state. The expandable eartip includes an insertion sensor configured to receive an indication that the eartip has been placed in an ear of a user. The expandable eartip further includes a controller configured to, in response, actuate a first device to inflate a first chamber to conform to a first portion of the ear. At least one advantage of the described techniques is that eartips in a set of earphones automatically inflate to provide an optimal fit for any listener'"'"'s ears.

Claims

1. A personal aural device, comprising:

an expandable eartip having a contracted state and an expanded state, the expandable eartip comprising;

an insertion sensor configured to receive an indication that the eartip has been placed in an ear of a user, and

a controller configured to, in response, actuate a first device to inflate a first chamber to conform to a first portion of the ear.

2. The personal aural device of claim 1, wherein receiving an indication that the eartip has been placed in the ear comprises receiving a signal that indicates a change in light level.

3. The personal aural device of claim 1, wherein receiving an indication that the eartip has been placed in the ear comprises receiving a signal that indicates the eartip is horizontally oriented.

4. The personal aural device of claim 1, wherein receiving an indication that the eartip has been placed in the ear comprises determining that an audio signal is being received by the personal aural device.

5. The personal aural device of claim 1, wherein receiving an indication that the eartip has been placed in the ear comprises receiving a signal that indicates a change in capacitance consistent with the eartip being in contact with human skin.

6. The personal aural device of claim 1, wherein actuating the first device comprises actuating a pump to introduce compressed air into the first chamber.

7. The personal aural device of claim 1, wherein actuating the first device comprises transmitting an electrical charge to the eartip to orient fibers associated with the first chamber.

8. The personal aural device of claim 1, further comprising an inflation sensor configured to transmit a signal to the controller that indicates an inflation level of the first chamber, and wherein the controller is further configured to determine that the first chamber has been inflated to a desired level.

9. The personal aural device of claim 8, wherein determining that the first chamber is inflated to a desired level comprises detecting a change in at least one operating characteristic of the first device.

10. The personal aural device of claim 8, wherein determining that the first chamber is inflated to a desired level comprises receiving a signal indicating that the first chamber has achieved a threshold pressure.

11. A computer-readable storage medium including instructions that, when executed by a processor, cause the processor to adjust an eartip associated with a personal aural device, by performing the steps of:

receiving an indication that the eartip has been placed in an ear of a user; and

in response, actuating a first device to inflate a first chamber to conform to a first portion of the ear.

12. The computer-readable storage medium of claim 11, wherein the first portion of the ear comprises a region of an ear canal.

13. The computer-readable storage medium of claim 11, wherein the first portion of the ear comprises a region of a concha.

14. The computer-readable storage medium of claim 11, wherein the instructions, instructions that, when executed by a processor, further cause the processor to perform the step of, in response to receiving an indication that the eartip has been placed in an ear of a user, actuating a second device to inflate a second chamber to inflate to conform to a second portion of the ear.

15. The computer-readable storage medium of claim 14, wherein the first portion of the ear comprises a region of an ear canal, and the second portion of the ear comprises a region of the concha.

16. A method for adjusting an eartip associated with a personal aural device, the method comprising:

receiving an indication that the eartip has been placed in an ear of a user; and

in response, actuating a first device to inflate a first chamber to conform to a first portion of the ear.

17. The method of claim 16, wherein the first portion of the ear comprises a region of an ear canal.

18. The method of claim 16, wherein the first portion of the ear comprises a region of a concha.

19. The method of claim 16, further comprising, in response to receiving an indication that the eartip has been placed in an ear of a user, actuating a second device to inflate a second chamber to inflate to conform to a second portion of the ear.

20. The method of claim 19, wherein the first portion of the ear comprises a region of an ear canal, and the second portion of the ear comprises a region of the concha.
