ABSTRACT:
A new voice tube assembly for post-auricle headsets is disclosed. In one aspect of the invention, first and second curved, rigid tubular sections are employed to connect a flexible main voice tube section with the top of a post-auricle capsule containing a microphone and a receiver. The curved, rigid tubing sections are rotatable to maximize positional flexibility. In a second aspect of the invention, a shaping wire is included throughout a substantial portion of the length of the main voice tube section. The shaping wire is employed in order to permit the use of thinner and lighter material for the main voice tube section, and to facilitate shaping of the main voice tube section to the geometry of the wearer's face and locating of the open end of the main voice tube section adjacent the wearer's mouth.
