Abstract

The present invention is directed to a pad and sound transmission system which is adapted to directly transmit audible sound waves into the body at high intensity levels. In one embodiment, the subject invention includes a back pad and a seat pad. Each pad includes a speaker module having an acoustic speaker disposed within the pad and surrounded by a plurality of different layers.

Claims

1-32. -32. (canceled)

33. A chair comprising:

a seat portion comprising a vibration source; and

,

a back portion comprising a speaker, a layered plurality of materials, and a resonant chamber, wherein at least a portion of the resonant chamber is defined within an aperture extending through at least one material of the layered plurality of materials, and wherein at least a portion of said aperture is configured to be positioned between the speaker and a user sitting in the chair.

34. The chair of claim 33, wherein the layered plurality of materials comprises a plurality of different foam elements.

35. The chair of claim 34, wherein the different foam elements have different degrees of compressibility.

36. The chair of claim 34, wherein the different foam elements have different degrees of acoustic conductance.

37. The chair of claim 33, wherein the speaker and the vibration source can each be independently controlled by the user.

38. The chair of claim 33, wherein the back portion of the chair comprises a plurality of speakers.

39. The chair of claim 38, wherein each speaker can be independently controlled by the user.

40. The chair of claim 33 further comprising an amplified sound source having an automatic volume control.

41. The chair of claim 40 further comprising a decibel sensor in communication with the automatic volume control.

42. The chair of claim 33 further comprising at least one activation switch located within the back portion, the seat portion, or both, the activation switch being in communication with an amplification system.

43. A chair comprising:

a seat portion comprising a vibration source; and

a back portion comprising a speaker and a resonant chamber, said back portion and said seat portion each comprising a layered plurality of materials,

wherein at least a portion of the resonant chamber is defined within an aperture extending through at least one material of the layered plurality of materials in the back portion of the chair, and wherein at least a portion of said aperture is configured to be positioned between the speaker and a user sitting in the chair.

44. The chair of claim 43, wherein the layered plurality of materials comprises a plurality of different foam elements.

45. The chair of claim 44, wherein the different foam elements have different degrees of compressibility.

46. The chair of claim 44, wherein the different foam elements have different degrees of acoustic conductance.

47. The chair of claim 43, wherein the speaker and the vibration source can each be independently controlled by the user.

48. The chair of claim 43, wherein the back portion of the chair comprises a plurality of speakers.

49. The chair of claim 48, wherein each speaker can be independently controlled by the user.

50. The chair of claim 43 further comprising an amplified sound source having an automatic volume control.

51. The chair of claim 50 further comprising a decibel sensor in communication with the automatic volume control.

52. The chair of claim 43 further comprising at least one activation switch located within the back portion, the seat portion, or both, the activation switch being in communication with an amplification system.
