Abstract
Abstract A speaker stand for supporting a speaker enclosure on the floor comprising a rigid planar member (11) supporting a waffled cushion pad (12) on the top surface with the pad including peaks 17 and valleys 19. Semiresilient rails (13, 14, 15, 16) positioned to the side of said pad support and stabilize the speaker enclosure such that the pad is depressed sufficiently to form air pockets between the pad and speaker enclosure in the areas of the valleys to attenuate vibratory motion and acoustic sound wave transmissions between the speaker and floor.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
139 words
A speaker stand for supporting a speaker enclosure on a floor and wherein the speaker has a base forming a planar bottom surface, said stand comprising: a rigid planar member having a top surface of sufficient size to support the base of the speaker enclosure; a waffled cushion member fixed to the top surface of said base, said cushion member comprising a top layer of resilient material forming a plurality of peaks and valleys facing upward so as to form a plurality of closed, air pockets with the speaker bottom surface to attenuate vibratory motion transmitted therebetween, a plurality of resilient members of less resiliency than said cushion member supported to the opposite sides of said cushion member to support and stabilize said speaker enclosure while preventing the leveling of said peaks with the valleys of the cushion member.
Claim 2
Dependent Claim
139 words
A speaker stand for supporting a speaker enclosure on a floor and wherein the speaker has a base forming a planar bottom surface, said stand comprising: a rigid planar member having a top surface of sufficient size to support the base of the speaker enclosure; a waffled cushion member fixed to the top surface of said base, said cushion member comprising a top layer of resilient material forming a plurality of peaks and valleys facing upward so as to form a plurality of closed, air pockets with the speaker bottom surface to attenuate vibratory motion transmitted therebetween, a plurality of resilient members of less resiliency than said cushion member supported to the opposite sides of said cushion member to support and stabilize said speaker enclosure while preventing the leveling of said peaks with the valleys of the cushion member.
Claim 3
Dependent Claim
38 words
A speaker stand as defined in claim 1 including a second base and rotatable means fixed to the bottom of the rigid planar member and said second base thereby allowing rotation of the speaker about a vertical axis.
Claim 4
Dependent Claim
45 words
A speaker stand as defined in claim 1 wherein said resilient members includes four resilient stabilizer rails fixed around the edges of said cushion member with one being raised sufficiently so as to tilt the speaker enclosure for better dispersion of sound within the room.
Claim 5
Dependent Claim
49 words
A speaker stand as defined in claim 1 including a support and means fixing said support to one edge of the rigid planar member to position said planar member at an angle to the floor so as to tilt the planar member and speaker enclosure relative to said floor.
Claim 6
Dependent Claim
47 words
A speaker stand as defined in claim 4 including a vertical planar member fixed to the opposite edge of said planar member from said one edge in a position to extend upward along said speaker enclosure to stabilize the speaker enclosure when tilted relative to the floor.
Claim 7
Independent Claim
87 words
The method of decoupling a speaker enclosure from a floor comprising the step of: supporting the speaker enclosure on a resilient pad having a top waffle surface having peaks and valleys and stabilizer rails fixed around the edges of said pad and being of sufficient rigidity to support the speaker enclosure high enough to form air pockets in the areas of the valleys and and between the speaker enclosure and the pad top surface to attenuate vibratory motion and acoustic sound waves transmitted from the speaker enclosure.
Claim 8
