Abstract
Abstract A vibrationless speaker assembly includes a speaker, an enclosure, and a speaker mount within the enclosure. The speaker mount is formed from alternate layers of rigid mounting blocks and vibration damping material with a split collar attached to one end of the mount. The other end of the mount is fixed in a speaker enclosure spaced from a baffle board having an orifice. An annular member of vibration damping material is secured around the periphery of the orifice. The speaker is mounted in the enclosure by pressing the speaker cone firmly against the annular member on the baffle board and securing the driving portion of the speaker by friction in the split collar to hold the speaker in position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
135 words
A vibrationless speaker assembly comprising, a speaker including a driving portion and a cone attached thereto, an enclosure having a baffle wall with an opening therein, an annular member of relatively rigid resilient material fixed to said baffle wall about said opening, a plurality of rigid support members fixed in said enclosure in spaced relation to said baffle wall, a plurality of vibration damping layers interleaved with said plurality of rigid support members, means securing each rigid support member to its immediately adjacent rigid support members through the adjacent vibration damping layer in a series of pairs, and collar means carried by said interleaved rigid support members and said vibration damping layers, said collar means engaging the driving portion of said speaker and retaining said speaker with the cone thereof disposed against said annular member.
Claim 2
Dependent Claim
135 words
A vibrationless speaker assembly comprising, a speaker including a driving portion and a cone attached thereto, an enclosure having a baffle wall with an opening therein, an annular member of relatively rigid resilient material fixed to said baffle wall about said opening, a plurality of rigid support members fixed in said enclosure in spaced relation to said baffle wall, a plurality of vibration damping layers interleaved with said plurality of rigid support members, means securing each rigid support member to its immediately adjacent rigid support members through the adjacent vibration damping layer in a series of pairs, and collar means carried by said interleaved rigid support members and said vibration damping layers, said collar means engaging the driving portion of said speaker and retaining said speaker with the cone thereof disposed against said annular member.
Claim 3
Dependent Claim
21 words
The invention as recited in claim 1 wherein each said vibration damping layer comprises multiple individual layers of vibration damping material.
Claim 4
Dependent Claim
16 words
The invention as recited in claim 1 wherein each said vibration damping layer comprises fibrous material.
Claim 5
Dependent Claim
16 words
The invention as recited in claim 1 wherein each said vibration damping layer comprises expanded material.
Claim 6
Dependent Claim
17 words
The invention according to claim 1 wherein said annular member comprises a ring of high density rubber.
Claim 7
Dependent Claim
42 words
The invention as recited in claim 1 wherein the interleaved rigid sUpport members and vibration damping layers are dimensioned to define a mount having a stepped configuration whereby a clearance precludes any contact between the mount and the cone of said speaker.
Claim 8
Dependent Claim
33 words
The invention as recited in claim 6 wherein the stepped configuration of said mount defines a generally pyramidal arrangement with each rigid support member being carried by its adjacent larger rigid support member.
