Abstract
Abstract A mobile microphone mounting system is disclosed for a mobile microphone having an encasement surrounding a microphone element. A rear wall of the encasement has a pocket with a thin wall at a base thereof. A ring-shaped magnet is positioned within the pocket with a flat major surface alongside the thin wall. A mounting member is mounted through a central aperture of the magnet to provide alternative mounting for the microphone. The magnet is positioned between a metal plate and the thin wall. A lip surrounding the pocket retains the plate and magnet therein. The microphone may be conveniently attached by magnetic attraction to any nearby surface or preferably to a cup-shaped metal mounting plate. A compatible clip assembly is also provided for alternative mounting.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
73 words
A mobile microphone mounting system, comprising: a mobile microphone having an encasement surrounding a microphone element; a rear wall of the encasement having a pocket with a thin wall at a base thereof; a magnet positioned within the pocket with a major surface thereof positioned alongside said thin wall; a thickness of the thin wall being sufficiently small to permit significant magnetic attraction therethrough; and means for retaining the magnet in the pocket.
Claim 2
Dependent Claim
73 words
A mobile microphone mounting system, comprising: a mobile microphone having an encasement surrounding a microphone element; a rear wall of the encasement having a pocket with a thin wall at a base thereof; a magnet positioned within the pocket with a major surface thereof positioned alongside said thin wall; a thickness of the thin wall being sufficiently small to permit significant magnetic attraction therethrough; and means for retaining the magnet in the pocket.
Claim 3
Dependent Claim
31 words
The system of claim 1 wherein the magnet has a ring-shape with a cylindrical side wall and flat end-surfaces, one of which is positioned parallel and adjacent to said thin wall.
Claim 4
Dependent Claim
20 words
The system of claim 2 wherein a mounting element is secured by a fastening member passing through the ring-shaped magnet.
Claim 5
Dependent Claim
13 words
The system of claim 3 wherein the mounting element comprises a mounting post.
Claim 6
Dependent Claim
19 words
The system of claim 1 wherein the thin wall is thinner than adjacent portions of the encasement rear wall.
Claim 7
Dependent Claim
22 words
The system of claim 1 wherein the pocket extends substantially outwardly of a plane defined by surrounding portions of the rear wall.
Claim 8
Dependent Claim
49 words
The system of claim 1 wherein a metal plate is positioned adjacent a surface of the magnet opposite said major surface and the magnet is secured within the pocket by securing means in contact with the metal plate, said metal plate increasing magnetic attraction external to the microphone encasement.
Claim 9
Dependent Claim
11 words
The system of claim 7 wherein the metal plate comprises zinc.
Claim 10
Dependent Claim
25 words
The system of claim 7 wherein a mounting member is attached to the metal plate by a screw passing through an aperture in the magnet.
Claim 11
Dependent Claim
35 words
The system of claim 1 wherein said means for retaining comprises a portion of the encasement forming a lip surrounding the pocket and the magnet and staked inwardly to retain the magnet within the pocket.
Claim 12
Dependent Claim
23 words
The system of claim 1 wherein a boss having a cup-shaped interior depends from said thin wall into an aperture of the magnet.
Claim 13
Dependent Claim
12 words
The system of claim 10 wherein a step portion defines the lip.
Claim 14
Dependent Claim
32 words
The system of claim 1 wherein a cup-shaped steel plate adapted to fit over a portion of the encasement retaining the magnet is provided to which the microphone may be magnetically attached.
Claim 15
Dependent Claim
39 words
The system of claim 1 wherein a metal mounting plate is fastened to a flexible aluminum plate, the aluminum plate being mounted to a surface in the vehicle and the microphone being magnetically attached to the metal mounting plate.
Claim 16
Dependent Claim
62 words
A mobile microphone mounting system, comprising: a microphone having an encasement surrounding a microphone element; a rear wall of the encasement having a plastic pocket with a thin plastic wall defining a portion of said rear wall; a magnet means within the encasement and within the pocket for mounting the microphone by magnetic attraction through said thin wall to nearby metal surfaces.
Claim 17
Dependent Claim
62 words
A mobile microphone mounting system, comprising: a microphone having an encasement surrounding a microphone element; a rear wall of the encasement having a plastic pocket with a thin plastic wall defining a portion of said rear wall; a magnet means within the encasement and within the pocket for mounting the microphone by magnetic attraction through said thin wall to nearby metal surfaces.
Claim 18
Dependent Claim
133 words
A mobile microphone mounting system, comprising: a mobile microphone having an encasement surrounding a microphone element; a rear wall of the encasement having a pocket with a base wall thinner than adjacent rear wall portions and sufficiently thin to permit mounting of the microphone to metal surfaces by magnetic attraction by a magnet positioned in the pocket; said magnet positioned within the pocket having a closed-loop shape with flat side walls perpendicular to the base wall and a central aperture; said magnet having flat parallel opposite faces lying between and in respective contact with the base wall and a metal plate; a mounting lip acting against said metal plate to retain said magnet in the pocket; and means for securing a mechanical mounting member to the metal plate through the magnet central aperture.
Claim 19
Dependent Claim
133 words
A mobile microphone mounting system, comprising: a mobile microphone having an encasement surrounding a microphone element; a rear wall of the encasement having a pocket with a base wall thinner than adjacent rear wall portions and sufficiently thin to permit mounting of the microphone to metal surfaces by magnetic attraction by a magnet positioned in the pocket; said magnet positioned within the pocket having a closed-loop shape with flat side walls perpendicular to the base wall and a central aperture; said magnet having flat parallel opposite faces lying between and in respective contact with the base wall and a metal plate; a mounting lip acting against said metal plate to retain said magnet in the pocket; and means for securing a mechanical mounting member to the metal plate through the magnet central aperture.
