A headset with an adjustable microphone boom (1) which can be adjusted to and from a position near the mouth of a user and is mounted in a housing (7) by a friction part (6) being coupled to a flexible friction coupling which is configured in a plate (9) in that co-operating plates (20, 21) are stamped out of the plate and are connected to the plate (9) by means of flexible arms (21, 27, 28, 32). The friction part (6) has a shaft (5) which can be accommodated in a bearing defined by recesses which are configured partly in the inside (8) of the housing (7) and partly in the pate (9). The microphone boom (1), the housing (7) and the plate (9) with friction coupling are held together by means of a locking ring (11). In this way a stable, adjustable microphone boom is provided which does not become loose with time, understood in the way that no matter in which position and regardless of how frequently the position is changed, the microphone boom will remain secured with a sufficient force in the friction coupling.
L'invention concerne un casque à tige microphonique ajustable (1) pouvant être ajustée pour atteindre une position près de la bouche d'un utilisateur ou en revenir, et montée sur un compartiment (7), au moyen d'une partie de friction (6) accouplée à une partie d'accouplement de friction souple, configurée dans une plaque (9), de sorte que des plaques coopérantes (20, 21) soient découpées à partir de ladite plaque, et accouplées à ladite plaque (9) à l'aide de bras souples (21, 27, 28, 32). La partie de friction (6) présente un arbre qui peut être adapté dans un palier défini par des renfoncements configurés partiellement dans la partie intérieure (8) du compartiment (7) et partiellement dans la plaque (9). La tige microphonique (1), le compartiment (7) et la plaque (9) à accouplement de friction sont maintenus ensemble au moyen d'un anneau de verrouillage (11). Ceci permet d'obtenir une tige microphonique ajustable stable qui ne se détache pas avec le temps : quelle que soit sa position et la fréquence des changements de position qu'elle subit, cette tige reste fixée avec une force suffisante à la partie d'accouplement de friction.
