Abstract
Abstract An arrangement for supporting electroacoustic transducers such as a microphone within a housing comprises a housing casing with a transducer within the casing supported by at least one elastic support ring provided between the transducer and the casing. The supporting ring is made of electrically conducting material providing electrical connection means to the housing. The housing itself or a portion thereof provides electrical terminal means for connecting the electrical transducer to an energy source.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
57 words
An arrangement for supporting electroacoustic transducers in a preferably rotationally symmetrical housing, comprising at least one elastic support ring provided between the transducer and the housing being made of an electrically conducting material providing electrical connection to said housing, an electrical terminal means connected to the outside of the housing and through said ring to said transducer.
Claim 2
Dependent Claim
57 words
An arrangement for supporting electroacoustic transducers in a preferably rotationally symmetrical housing, comprising at least one elastic support ring provided between the transducer and the housing being made of an electrically conducting material providing electrical connection to said housing, an electrical terminal means connected to the outside of the housing and through said ring to said transducer.
Claim 3
Dependent Claim
28 words
An arrangement according to claim 1, wherein the elastic material of said support ring comprises predominantly silicone rubber having an electrical resistivity of about 0.5 Ohms per cm.
Claim 4
Dependent Claim
37 words
An arrangement according to claim 1, wherein said elastic support ring comprises a butyl rubber and has an electrical resistivity of about 0.5 Ohms per cm. and a frequency dependent internal friction which decreases the increasing frequency.
Claim 5
Dependent Claim
50 words
A microphone comprising a cylindrical housing, a cylindrical transducer located within said housing and spaced from the interior thereof and an elastic ring supporting said transducer extending between said transducer and the housing and being of electrically conducting material and providing an electrical connection between said transducer to said housing.
Claim 6
Dependent Claim
50 words
A microphone comprising a cylindrical housing, a cylindrical transducer located within said housing and spaced from the interior thereof and an elastic ring supporting said transducer extending between said transducer and the housing and being of electrically conducting material and providing an electrical connection between said transducer to said housing.
Claim 7
Dependent Claim
36 words
A microphone according to claim 4, wherein said ring includes a plurality of radial extending spoke portions and including an inner hub ring portion surrounding said transducer and an outer ring portion engaged with said housing.
