Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
88 words
An acoustic energy transmission device comprising, first and second electro-acoustic transducers, each said transducer including an electrical circuit and a force exerting surface, an elongated substantially void free wave guide having first and second end portions, said guide comprising not less than 40% of inorganic electrically non-conducting low mass density fibers and a plastic binder bonding said fibers together, first means holding said surface of said first transducer to said first end portion and second means holding said surface of said second transducer to said second end portion.
Claim 2
Dependent Claim
88 words
An acoustic energy transmission device comprising, first and second electro-acoustic transducers, each said transducer including an electrical circuit and a force exerting surface, an elongated substantially void free wave guide having first and second end portions, said guide comprising not less than 40% of inorganic electrically non-conducting low mass density fibers and a plastic binder bonding said fibers together, first means holding said surface of said first transducer to said first end portion and second means holding said surface of said second transducer to said second end portion.
Claim 3
Dependent Claim
17 words
The combination of claim 1 in which said fibers are not greater than 0.01 inch in diameter.
Claim 4
Dependent Claim
22 words
The combination of claim 2 in which said fibers extend parallel to each other and spiral along the axis of said guide.
Claim 5
Dependent Claim
19 words
The combination of claim 2 in which said guide comprises a plural number of separate groups of said fibers.
Claim 6
Dependent Claim
21 words
The combination of claim 4 in which said groups are spaced from each other to provide integral groups of said fibers.
Claim 7
Dependent Claim
60 words
The combination of claim 1 in which said holding means includes a supporting member secured to the end portion of said guide with which it is associated, each said holding means further including means supported by its said supporting member and resiliently holding the said surface of the associated said transducer against the associated said end portion of said guide.
