Patent ID: 8774439

Claim:
A communication headset comprising: a housing, a peripheral slot extending along at least 180 degrees of the periphery of the housing in an intersecting plane that intersects the housing, a space extending in the intersecting plane and communicating with the slot, a porous material being arranged in the space, a first microphone transducer arranged in the housing, the first microphone transducer comprising a microphone opening, which is connected to the space, wherein the peripheral slot extends along the main part of the periphery of the housing and wherein the housing comprises a first housing part and a second housing part, which are divided by the peripheral slot which is bridged by a plate shaped part of said porous material provided between the first and second housing parts and extending around at least a portion of the periphery in said slot, the porous materials extending up to the outer surfaces of the housing parts at the slot so to define a contiguous smooth outer housing surface across the slot flush with the surfaces of said first and second parts and wherein said porous material together with said housing parts creates a substantial aerodynamically smooth surface and said material fills out the slot and provides a continuous surface with the housing surface, and wherein a plate shaped part of acoustically said porous material said material being rigid and largely wind impervious and which is self supporting to be able to support the interconnection between the housing parts is provided between the first housing part and the second housing part, and wherein said microphone is located immediately adjacent said plate shaped part but generally perpendicular to the plane of the said plate shaped part, thereby providing a substantially acoustically barrier free path audio path, aside from the porous material, between said slot and said microphone.
