A telephone commu- nication headset for attach- ment to the outer ear of an operator and comprising a main unit (3) which sup- ports an arm (2) with a mi- crophone (1) at its outer end, and an earphone (5) on the main unit. Further- more, a U-shaped support (6) is arranged with a first and a second downwardly- directed shank, said sup- port (6) being attached to the main unit. A con- necting upper portion (9) is arranged between the two shanks, which portions is arranged, in a position of use, to rest against the up- permost point of the outer ear, where the outer ear attaches to the skull. A weight (11) is arranged so that its mass and leverage presses the rear shank (10) of the support (6) towards the rear side of the outer ear and into the fold between the outer ear and the skull. The effect of gravity on the microphone (1) and the microphone-arm (2) is also counter-balanced. The telephone headset is hereby held in position by the pressing action of the rear shank and the torque about said suspension point by way of gravity.
Combiné téléphonique auriculaire s'attachant à l'oreille externe d'un opérateur et comprenant une unité principale (3) renfermant un écouteur (5) et portant un bras (2) pourvu à son extrémité d'un microphone (1). De plus, un support en U dont les branches partent vers le bas est fixé à l'unité principale. Les deux branches sont reliées par un élément supérieur de liaison (9) conçu pour reposer sur le sommet du point d'attache de l'oreille externe au crâne. Il est prévu un contrepoids (11) dont la masse et l'effet de levier poussent la branche arrière (10) du support (6) vers l'arrière de l'oreille externe dans le pli séparant le pavillon du crâne; l'action de la gravité sur le microphone (1) et sur son bras support (2) est ainsi contrebalancée, et le combiné se trouve maintenu en place par la pression de la branche arrière et par le couple exercé par la gravité autour du point de suspension.
