Abstract
Abstract A boom for adjustably mounting a microphone in proximity to the mouth of an operator. A housing is rotatably disposed on a headphone and includes internally disposed commutators which are operable to provide a switching and slidable contacting function. A boom member is slidably disposed in a laterally extending aperture in the housing and includes an internally disposed extendable conductor that is conductively connected to the commutators and to a microphone that is rotatably mounted on the remote end of the boom.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
132 words
In apparatus of the class above described, a rotatable, extensible microphone boom comprising in combination; a generally flat housing, said housing having an axis of rotation about an axis extending normal to the flat surfaces thereof and an interior chamber having an aperture extending outwardly through a minor sidewall of said housing and conductive terminal means adopted to slidably conductively engage stationary conductive means, adapted to be connected to a source of electrical signal, as said housing is rotated about said axis of rotation; an elongated hollow boom member slidably disposed in said aperture for limited lateral movement with respect to said axis of rotation; and conductor means having one end extending outwardly through said boom and a second end connected to said terminal means in the chamber in said flat housing.
Claim 2
Dependent Claim
132 words
In apparatus of the class above described, a rotatable, extensible microphone boom comprising in combination; a generally flat housing, said housing having an axis of rotation about an axis extending normal to the flat surfaces thereof and an interior chamber having an aperture extending outwardly through a minor sidewall of said housing and conductive terminal means adopted to slidably conductively engage stationary conductive means, adapted to be connected to a source of electrical signal, as said housing is rotated about said axis of rotation; an elongated hollow boom member slidably disposed in said aperture for limited lateral movement with respect to said axis of rotation; and conductor means having one end extending outwardly through said boom and a second end connected to said terminal means in the chamber in said flat housing.
Claim 3
Dependent Claim
68 words
The apparatus of claim 1 in which the flat housing is rotatably mounted upon an earcup of a headset and the headset includes arcuate conductive means and the terminal means on said flat housing and the arcuate conductive means are disposed concentrically of the axis of rotation of said flat housing on said earcup whereby conductive engagement of the arcuate conductive means by the terminal means is effected.
Claim 4
Dependent Claim
24 words
The apparatus of claim 2 in which at least one of the arcuate conductive means extends over an arc of less than 360 *.
Claim 5
Dependent Claim
37 words
The apparatus of claim 2 in which the conductor means are comprised of a plurality of parallel insulated conductors formed in a longitudinally elongated helix through at least a portion of the inside of the hollow boom.
Claim 6
Dependent Claim
37 words
The apparatus of claim 3 in which the conductor means are comprised of a plurality of parallel insulated conductors formed in a longitudinally elongated helix through at least a portion of the inside of the hollow boom.
