ABSTRACT:
An electronic artificial larynx supported and operated without the use of an operator's hands. The electronic larynx includes a headband which fits securely around the operator's head. A switch is attached to the headband for opening and closing an electrical circuit that includes a signal generator and a tone generator. The switch has a displaceable actuator extending beyond the headband and adherable to the operator's forehead for movement with the forehead relative to the headband. A hollow, non-toxic plastic tube has one end rotatably connected to a stem of the tone generator and another end for placement in the operator's mouth. A linkage assembly connects the tone generator to the headband for permitting universal adjustment of positioning of the tube.
