Haptic feedback for head-wearable speaker mount such as headphones or earbuds to indicate ambient sound

1. A device, comprising:

at least one computer memory that is not a transitory signal and that comprises instructions executable by at least one processor to:

sense ambient sound;

determine at least one parameter of the ambient sound; and

based at least in part on the at least one parameter, activate at least one haptic generator, wherein the instructions are executable to:

responsive to identifying the at least one parameter of ambient sound as noise from an approaching vehicle and to identifying the device is in a street, the instructions are executable to return a first tactile signal; and responsive to identifying the at least one parameter of ambient sound as noise from an approaching vehicle and to identifying the device is on a sidewalk, the instructions are executable to return a second tactile signal different from the first tactile signal.

2. The device of claim 1 , wherein the at least one parameter comprises a type of sound.

3. The device of claim 1 , wherein the at least one parameter comprises a direction of sound.

4. The device of claim 1 , wherein the at least one parameter comprises a location of sound origination.

5. The device of claim 1 , wherein the at least one parameter comprises an amplitude of sound.

6. The device of claim 1 , wherein the at least one parameter comprises speech in the ambient sound.

7. The device of claim 1 , wherein the instructions are executable to, based at least in part on the at least one parameter, establish a location of haptic feedback on a head-wearable speaker assembly.

8. The device of claim 1 , wherein the instructions are executable to, based at least in part on the at least one parameter, establish an intensity of haptic feedback on a head-wearable speaker assembly.

9. The device of claim 1 , wherein the instructions are executable to, based at least in part on a speaker volume of a head-wearable speaker assembly, establish an intensity of haptic feedback on the head-wearable speaker assembly.

10. The device of claim 1 , comprising the at least one processor.

11. A method comprising:

identifying that ambient sound impinging on a wearable listening device is correlated to a moving vehicle;

responsive to identifying that the ambient sound is correlated to a moving vehicle and to identifying that the device is in a first type of location, return a first haptic feedback signal; and

responsive to identifying, that the ambient sound is correlated to a moving vehicle and to identifying that the device is in a second type of location, return a second haptic feedback signal.

12. The method of claim 11 , wherein the wearable listening device comprises noise-canceling earbuds.

13. The method of claim 11 , wherein the identifying the ambient sound is based at least in part on a type of sound.

14. The method of claim 11 , wherein the identifying the ambient sound is based at least in part on a direction of sound.

15. The method of claim 11 , wherein the identifying the ambient sound is based at least in part on an amplitude of sound.

16. The method of claim 11 , comprising, based at least in part on the ambient sound, establishing a location of haptic feedback on the wearable listening device.

17. The method of claim 11 , comprising, based at least in part on the ambient sound, establishing an intensity of haptic feedback on the wearable listening device.

18. The method of claim 11 , comprising, based at least in part on the ambient sound, establishing an intensity of haptic feedback on headphones.

19. The device of claim 1 , comprising a head-wearable headphone assembly, the at least one haptic generator being on the head-wearable headphone assembly.

20. The device of claim 19 , wherein the ambient sound is sensed by at least one microphone on the head-wearable headphone assembly.
