Abstract

An automatic lacing system for an article of footwear includes a motor, a gear train coupled to the motor, a speaker, and a speaker controller in communication with the speaker and the motor. The speaker controller is configured to instruct the speaker to output a damping sound wave in response to activation of the motor to reduce or cancel sound generated by the motor or the gear train.

First claim

I claim:

1. An automatic lacing system for an article of footwear, comprising:
a motor;
a gear train coupled to the motor;
a speaker; and
a speaker controller in communication with the speaker and the motor, wherein the speaker controller is configured to instruct the speaker to output a damping sound wave in response to activation of the motor to reduce or cancel sound generated by the motor or the gear train.

2. The automatic lacing system of claim 1 , further comprising a housing supporting the motor and the gear train.

3. The automatic lacing system of claim 2 , wherein the speaker is enclosed within the housing.

4. The automatic lacing system of claim 1 , wherein the speaker is arranged adjacent to the gear train.

5. The automatic lacing system of claim 1 , wherein the motor is activated in response to an input to a panel of the automatic lacing system.

6. The automatic lacing system of claim 1 , wherein the motor is activated in response to an input to a wireless device in communication with the automatic lacing system.

7. The automatic lacing system of claim 1 , further comprising a microphone in communication with the speaker controller and being configured to record the sound generated by the motor or the gear train.

8. The automatic lacing system of claim 7 , wherein the speaker controller is configured to instruct the microphone to begin recording the sound generated by the motor or the gear train in response to activation of the motor.

9. The automatic lacing system of claim 8 , wherein the speaker controller is configured to adjust a magnitude and a phase of the damping sound wave in response to the recorded sound of the microphone.

10. The automatic lacing system of claim 9 , wherein the speaker controller is configured to output the damping sound wave with the magnitude being approximately equal to a magnitude of the recorded sound of the microphone and the phase being inverted relative to the recorded sound of the microphone.

11. An automatic lacing system for an article of footwear, comprising:
a motor;
a gear train coupled to the motor, the gear train comprising a wheel gear that defines an axis of rotation; and
a sound damping panel configured to damp sound and arranged between the gear train and a cover,
wherein the sound damping panel is configured to absorb at least a portion of the sound generated by the motor or the gear train during activation of the motor, and
wherein the axis of rotation of the wheel gear extends through the sound damping panel and the cover.

12. The automatic lacing system of claim 11 , wherein the sound damping panel is fabricated from a cork material, a non-woven fiber material, a rubber material, a vinyl material, a mass loaded vinyl material, a polymeric material, a foam material, a rubberized foam material, an expanded thermoplastic polymeric material, or a porous material.

13. The automatic lacing system of claim 11 , wherein the sound damping panel includes two or more layers, and wherein at least two of the two or more layers are fabricated from a different material.

14. The automatic lacing system of claim 13 , wherein at least two of the two or more layers are fabricated from a same material.

15. The automatic lacing system of claim 11 , wherein the sound damping panel includes a plurality of sound proofing panels arranged in a grid.

16. The automatic lacing system of claim 11 , wherein each of the sound proofing panels includes a structured surface defining at least one of a plurality of recesses and a plurality of protrusions.

17. An automatic lacing system for an article of footwear, comprising:
a motor;
a gear train coupled to the motor;
a housing supporting the motor and the gear train; and
a seal configured to damp sound and attached to the housing and in engagement with a top cover,
wherein the seal is disposed between the top cover and housing and in direct physical contact with the top cover.

18. The automatic lacing system of claim 17 , wherein the seal is arranged around a periphery of the housing and is in engagement with the top cover to enclose the motor and the gear train between the housing and the top cover.

19. The automatic lacing system of claim 17 , wherein the housing includes a gear train aperture configured to receive at least a portion of the gear train.

20. The automatic lacing system of claim 19 , wherein the seal is arranged around a periphery of the gear train aperture and is in engagement with the gear train housing to enclose the gear train between the gear train aperture and the gear train housing.
