TELEPHONE COMMUNICATION HEADSET
摘要:
A telephone communication headset for attachment to the outer ear of an operator and comprising a main unit (3) which supports an arm (2) with a microphone (1) at its outer end, and an earphone (5) on the main unit. Furthermore, a U-shaped support (6) is arranged with a first and a second downwardly-directed shank, said support (6) being attached to the main unit. A connecting upper portion (9) is arranged between the two shanks, which portions is arranged, in a position of use, to rest against the uppermost 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.
