Abstract

Systems and methods for applying vibration to the human body. A vibration system includes a vibrator capable of converting an electrical signal into vibration. In one aspect, the vibrator is arranged on or about the human body on a pectoralis major muscle and spaced away from a sternum. In another aspect, the vibrator is arranged on or about the human body such that a first pattern of vibrations are generated on the body'"'"'s surface. The first pattern of vibrations matches in relative amplitude a second pattern of vibrations generated on the body'"'"'s surface when the body generates sound.

Claims

1. A vibration system comprising a vibrator capable of converting an electrical signal into vibration, arranged on or about a human body on a pectoralis major muscle and spaced away from a sternum.

2. The system of claim 1, further comprising a support structure for arranging the vibrator.

3. The system of claim 1, further comprising an audio speaker for generating sound.

4. The system of claim 1, further comprising a second vibrator arranged on or about the body on a pectoralis major muscle and spaced away from the sternum.

5. The system of claim 4, wherein the support structure disposes the vibrators on a front-back coronal plane of the body and symmetrically across a left-right median plane of the body.

6. The system of claim 2, wherein the support structure includes a curved harness adapted to fit over a shoulder of the body and having two ends configured to flex inwardly toward each other.

7. The system of claim 6, wherein the support structure includes a second curved harness adapted to fit over a shoulder of the body and having two ends configured to flex inwardly toward each other.

8. The system of claim 7, wherein the two ends of each curved harness are adapted to flex inwardly and push a vibrator against the body.

9. The system of claim 8, further comprising an adjustable endpiece nested within a free end of each curved harness and capable of sliding in and out of the free end.

10. The system of claim 8, further comprising an adductor joint at a point of attachment of the two curved harnesses, adapted to adduct the two curved harnesses.

11. The system of claim 8, further comprising a harness joint at a midsection of each curved harness adapted to allow a free end of each curved harness to fold towards a point of attachment of the two curved harnesses.

12. The system of claim 8, further comprising a vibrator joint at a point of attachment of a vibrator to a free end of a curved harness, adapted to adjust an angle between the vibrator and the free end.

13. The system of claim 8, further comprising a vibrator positioned at a point of attachment of the two curved harnesses, adapted to convert a rear channel electrical audio signal of a surround sound system into a vibration.

14. The system of claim 2, wherein the support structure includes a bent element adapted to fit on a front of a shoulder of the body and having an end adapted to attach to the vibrator.

15. The system of claim 14, further comprising a vibrator joint at a point of attachment of the vibrator to the bent element, adapted to adjust an angle between the vibrator and the bent element.

16. The system of claim 14, wherein the support structure includes a semi-circular element adapted to fit around a back of a neck of the body and having two ends each adapted to attach to a bent element.

17. The system of claim 16, further comprising a bent element joint at a point of attachment of a bent element to the semi-circular element, adapted to fold the bent element and the semi-circular element together in a common plane.

18. The system of claim 16, wherein the support structure includes a long element vertically centered on an upper back of the body, attached to a midpoint of the semi-circular element at an angle adapted to push a vibrator against the body.

19. The system of claim 18, further comprising a midpoint joint at a point of attachment of the long element to the semi-circular element, adapted to fold the two elements together in a common plane.

20. The system of claim 2, wherein the support structure includes a first stretchable band adapted to fit around a neck, a second stretchable band connected to the first stretchable band and adapted to depend from the first stretchable band, and a fastener adapted to fasten the second stretchable band to a waistband.
