Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
69 words
A sound reproduction chember, comprising: a diaphragm enclosure including a pair of parabolic diaphragm covers disposed at a suitable distance apart and opposingly with their foci juxtapositioned in cross-sectional alignment, a frame enclosing the space between said diaphragm covers about the perimeter of said diaphragm covers; and a resonating generator communicating into the interior of said diaphragm enclosure being connected directly to vibrate said diaphragm enclosure to produce sound.
Claim 2
Dependent Claim
69 words
A sound reproduction chember, comprising: a diaphragm enclosure including a pair of parabolic diaphragm covers disposed at a suitable distance apart and opposingly with their foci juxtapositioned in cross-sectional alignment, a frame enclosing the space between said diaphragm covers about the perimeter of said diaphragm covers; and a resonating generator communicating into the interior of said diaphragm enclosure being connected directly to vibrate said diaphragm enclosure to produce sound.
Claim 3
Dependent Claim
39 words
The apparatus of claim 1 wherein each of said parabolic diaphragm covers are disposed concavely with respect to the outside of said diaphragm enclosure with their points of deepest curvature disposed adjacently at a suitable distance to one another.
Claim 4
Dependent Claim
24 words
The apparatus of claim 1 wherein each of said parabolic diaphragm covers are disposed convexly with respect to the outside of said diaphragm enclosure.
Claim 5
Dependent Claim
30 words
The apparatus of claim 3 wherein said frame is rectangular and each side forming said frame is substantially ellipitical configuration to mate with the perimeter edges of said diaphragm covers.
Claim 6
Dependent Claim
23 words
