ABSTRACT:
A sound powered headset has a curved headband with stirrups mounted at its opposite ends for pivotal movement about first axes. Earphone assemblies are supported by the stirrups for pivotal movement about second axes extending transversely to the first axes. The headband is configured to operatively position the earphone assemblies over the user's ears. A microphone assembly is supported by tubular arm members which are connected to each of the earphone assemblies for rotation about a third axis extending transversely to the aforesaid first and second axes. The microphone assembly contains a known device for converting sound waves to electrical impulses and the earphone assemblies likewise contain known devices for converting electrical impulses to sound waves. The arm members are sufficiently rigid to maintain the microphone assembly spaced in front of the user's mouth when the earphone assemblies are operatively positioned. The arm members are also sufficiently flexible to permit limited positional adjustment of the microphone assembly. The microphone assembly and the earphone assemblies are electrically interconnected by conductor wires extending through the arm members.
