Abstract

Transducers and resonators are embedded in body support structures in contact with a user to for the purpose of conveying musical sound energy to a user'"'"'s body at selected frequencies and in selected patterns. Body support structures comprise beds, pillows, chairs, and other structures typically used to support people. The sound may be audio tones and/or music. The transducers and resonators may be incorporated into a foam component or in a coil spring component of the body support structure. Latex-type foams and beds made with springs are candidate body support structures for receiving transducer'"'"'s and resonators. Electro-active polymers are also used as transducers. Floor systems are activated by both mechanical transducers and electro-active polymers.

Claims

1. A method of inducing tactile stimulation of a user by activating a floor system using mechanical transducers comprising:

providing a floor deck made from a material that is capable of inducing said tactile stimulation;

attaching isolators to said floor deck to isolate said floor deck from a floor base;

attaching a mechanical transducer to a vibrational plate;

attaching said vibrational plate to said floor deck;

generating tonal vibrations in said mechanical transducer in response to a tonal frequency signal that is applied to said mechanical transducer so that said tonal vibrations relating to said tonal frequencies are transmitted to said vibrational plate and to said floor deck to induce tactile stimulation of said user of said tonal vibrations.

2. The method of claim 1 wherein said process of attaching said vibrational plate to said floor deck further comprises:

attaching said vibrational plate in a recessed portion of said floor deck so that said vibrational plate is substantially flush with said floor deck and said mechanical transducer is disposed between said floor deck and a floor base.

3. The method of claim 1 wherein said process of attaching said vibrational plate to said floor deck further comprises:

attaching said vibrational plate to a top surface of said floor deck so that said mechanical transducer is mounted above said floor deck.

4. The method of claim 2 further comprising:

attaching a plurality of mechanical transducers to said floor deck in a rectangular pattern.

5. The method of claim 2 further comprising:

attaching a plurality of mechanical transducers around peripheral portions of said floor deck.

6. The method of claim 2 further comprising:

attaching a plurality of mechanical transducers to said floor deck in a circular pattern.

7. The method of claim 3 further comprising:

attaching a plurality of mechanical transducers to said floor deck in a rectangular pattern.

8. The method of claim 3 further comprising:

attaching a plurality of mechanical transducers around peripheral portions of said floor deck.

9. The method of claim 3 further comprising:

attaching a plurality of mechanical transducers to said floor deck in a circular pattern.

10. A method of inducing tactile stimulation of a user by activating a floor system using EAP transducers comprising:

providing a floor deck made from a material that is capable of inducing said tactile stimulation;

attaching said EAP transducers to said floor deck between said floor deck and a floor base;

applying a tonal frequency signal to said EAP transducers;

generating tonal vibrations, in said EAP transducers in response to said tonal frequency signal, that are transmitted to said floor deck to induce said tactile stimulation of said user.

11. The method of claim 10 further comprising:

providing resilient isolators between said floor deck and said EAP transducers to isolate and cushion said floor deck from said floor base, and prevent said floor deck from bouncing on said floor base.

12. The method of claim 10 wherein said process of attaching said EAP transducers to said floor deck further comprises:

attaching said EAP transducers to said floor deck in a rectangular pattern.

13. The method of claim 10 wherein said process of attaching said EAP transducers to said floor deck further comprises:

attaching said EAP transducers to said floor deck around peripheral portions of said floor deck.

14. The method of claim 10 wherein said process of attaching said EAP transducers to said floor deck further comprises:

attaching said EAP transducers to said floor deck in a circular pattern.

15. A method of inducing tactile stimulation of a user by activating an EAP transducer pad using EAP transducers comprising:

providing a structural support layer that is constructed from a semi-rigid material;

attaching said EAP transducers to said structural support layer;

providing a top surface layer constructed from a closed cell foam;

attaching said top surface layer to said structural support layer so that said top surface layer is disposed over said EAP transducers;

attaching a bottom surface layer to said structural support layer;

applying a tonal frequency signal to an electronics package that is attached to said EAP transducer pad;

generating tonal vibrations in said EAP transducers, in response to said tonal frequency signal, that are transmitted to said top surface layer to induce tactile stimulation of a user disposed on said EAP transducer pad.

16. A combined spring and electro-active polymer transducer comprising:

a coil spring having a first end support and a second end support;

at least one central support connected to said first end support and said second end support, said central support having an integrally formed electro-active polymer structure that forms a portion of central support, and that expands and contracts in response to a tonal frequency signal applied to said electro-active polymer structure, causing said coil spring to expand and contract in response to said tonal frequency signal;

an electro-active polymer transducer connected to said first end support that expands and contracts in response to said tonal frequency signal.
