Abstract
Abstract An electrically chargeable plate of predetermined surface area is retained in contact with the skin of each of two participants. An electrical conductor connects each plate to one of the two terminals of the audio output of one of the channels of a stereo amplifier while the other channel plays through its speaker. Physical contact between the participants completes the circuit enabling both participants to feel the modulated impulses of the sound as well as hear the output of the speaker on the other channel. Both plates may be worn by one person to experience a comparable feeling or one plate and an electrically chargeable wand used in place of or in addition to the other plate enables either one or two persons to participate.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
128 words
A device for feeling music being played through a first channel of a stereo amplifier having a pair of output terminals for said channel by applying the output of said first channel through the bodies of one or more participants while the music on the other channel is being played through a speaker, said device comprising a pair of electrically chargeable conductors, each having an exposed surface area for contacting the skin of a participant, a lead wire electrically secured at one end to each of said conductors and having an opposite end adapted to connect to one of said output terminals, at least one of said lead wires having a replaceable interposed fuse to limit the current output between the two amplifier terminals of said first channel.
Claim 2
Independent Claim
128 words
A device for feeling music being played through a first channel of a stereo amplifier having a pair of output terminals for said channel by applying the output of said first channel through the bodies of one or more participants while the music on the other channel is being played through a speaker, said device comprising a pair of electrically chargeable conductors, each having an exposed surface area for contacting the skin of a participant, a lead wire electrically secured at one end to each of said conductors and having an opposite end adapted to connect to one of said output terminals, at least one of said lead wires having a replaceable interposed fuse to limit the current output between the two amplifier terminals of said first channel.
Claim 3
Dependent Claim
44 words
The device defined in claim 1 in which one of said conductors is an elongated sheet of an electrical conductor material formed as a component of a torso encircling belt with said exposed skin contacting surface located along the interior surface of the belt.
Claim 4
Dependent Claim
109 words
The device defined in claim 2 in which said belt is a sheet of thin flexible metal forming said electrical conductor, said lead wire securing to said conductor being a wire connector terminating said lead wire first end located on the exterior facing side of said belt and connected by a rivet passing through said metal sheet, and size adjustable buckling means for said belt including a hook fastened to and extending from one end of said sheet and a series of spaced openings formed along a midline of the sheet adjacent the opposite end of the sheet, said openings being sized for selective releasable engagement by said hook.
Claim 5
Dependent Claim
27 words
The device defined in claim 3 in which said metal sheet is formed with beaded edges and an electrical insulating coating on the exterior facing surface thereof.
Claim 6
Dependent Claim
36 words
The device defined in claim 2 in which said belt is formed as a laminated structure having a supporting layer of plastic sheet material and said conductor is a metal foil layer lining said supporting layer.
Claim 7
Dependent Claim
46 words
The device defined in claim 1 in which a supporting sheet of plastic material forms a torso encircling belt and said conductors are a pair of metal foil layers arranged in spaced relation insulated from each other on an interior facing side of said supporting sheet.
Claim 8
Dependent Claim
38 words
The device defined in claim 1 in which one of said conductors is a metal tubing formed as a component of a wand sized for grasping by the hand of a participant as said skin contacting surface area.
Claim 9
Dependent Claim
58 words
The device defined in claim 7 in which a cap terminates one end of said tubing and said lead wire first end extends through an opening in said cap, said lead wire securing to the conductor being a wire connector terminating said lead wire first end and connected by a rivet passing through the wall of the tubing.
Claim 10
Dependent Claim
55 words
The device defined in claim 1 including a third electrically chargeable conductor and a lead wire electrically secured at one end thereof to said third conductor and having an opposite end adapted to connect to one of said output terminals in parallel with one of the conductors and lead wires of said first mentioned pair.
Claim 11
Dependent Claim
76 words
The device defined in claim 9 in which each of said pair of conductors is an elongated sheet of an electrical conductor material formed as a component of a torso encircling belt with said exposed skin contacting surface located along the interior facing side of the belt, said third conductor being a metal tubing formed as a component of a wand sized for grasping by the hand of a participant as said skin contacting surface area.
Claim 12
Dependent Claim
31 words
The device defined in claim 2 in which the skin contacting area of the conductor formed as a component of a torso encircling belt is between 90 to 130 sq. inches.
