ABSTRACT:
A headset with an adjustable microphone boom which can be adjusted to and from a position near the mouth of a user and is mounted in a housing by a friction part being coupled to a flexible friction coupling which is configured in a plate in that co-operating plates are stamped out of the plate and are connected to the plate by means of flexible arms. The friction part has a shaft which can be accommodated in a bearing defined by recesses which are configured partly in the inside of the housing and partly in the plate. The microphone boom, the housing and the plate with friction coupling are held together by means of a locking ring. 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.
