Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
96 words
An acoustic apparatus which, including a reproduction mechanism portion and a container for containing the same, comprises: a suspension mechanism provided between the reproduction mechanism portion and the container, said mechanism including a first elastic element and a second elastic element; said second elastic element comprising a pillar shaped viscous-elastic body produced to include a hollow section inside thereof; the upper and the lower end of said second elastic element being fixed to the reproduction mechanism portion and the contanier, respectively; and said first elastic element comprising a coil spring provided surrounding said second elastic element.
Claim 2
Dependent Claim
96 words
An acoustic apparatus which, including a reproduction mechanism portion and a container for containing the same, comprises: a suspension mechanism provided between the reproduction mechanism portion and the container, said mechanism including a first elastic element and a second elastic element; said second elastic element comprising a pillar shaped viscous-elastic body produced to include a hollow section inside thereof; the upper and the lower end of said second elastic element being fixed to the reproduction mechanism portion and the contanier, respectively; and said first elastic element comprising a coil spring provided surrounding said second elastic element.
Claim 3
Dependent Claim
56 words
An acoustic apparatus as defined in claim 1, wherein said second elastic element is provided with an upper and lower fixing post whose one ends are provided embedded at the upper and the lower end of said second elastic element, respectively, and the other ends are fixed to the reproduction mechanism portion and the container, respectively.
Claim 4
Dependent Claim
30 words
An acoustic apparatus as defined in claim 1, wherein said first and said second elastic elements are provided in a diagonal direction between the reproduction mechanism portion and the container.
Claim 5
Dependent Claim
100 words
An acoustic apparatus which, including a reproduction mechanism portion and a container for containing the same, comprises: a suspension mechanism provided between the reproduction mechanism portion and the container, said mechanism including a first elastic element and a second elastic element; said second elastic element comprising a pillar shaped viscouse elastic body including a liquid body in a hollow section produced inside thereof; the upper and the lower end of said second elastic element being fixed to the reproduction mechanism portion and the container, respectively; and said first elastic element comprising a coil spring provided surrounding the second elastic element.
Claim 6
Dependent Claim
100 words
An acoustic apparatus which, including a reproduction mechanism portion and a container for containing the same, comprises: a suspension mechanism provided between the reproduction mechanism portion and the container, said mechanism including a first elastic element and a second elastic element; said second elastic element comprising a pillar shaped viscouse elastic body including a liquid body in a hollow section produced inside thereof; the upper and the lower end of said second elastic element being fixed to the reproduction mechanism portion and the container, respectively; and said first elastic element comprising a coil spring provided surrounding the second elastic element.
Claim 7
Dependent Claim
40 words
An acoustic apparatus as defined in claim 4, wherein said first elastic element is intended to support the weight of the reproduction mechanism portion, and said second elastic element is intended to abosrb vibrations transmitted to the reproduction mechanism portion.
