Abstract
A voice transmission system for a conventional gas mask or face mask includes a body enclosing a microphone, an amplifier assembly and a speaker. The microphone is mounted within a cavity formed in the body, while the amplifier assembly and speaker are mounted within a main compartment of the body. The microphone, amplifier assembly, speaker and a set of batteries are electrically interconnected. The batteries are enclosed within one or more battery compartments in the body. A mounting assembly having a bracket with threaded, resilient segments is also connected to the body. The resilient segments of the bracket are designed to releasably couple the body to the voice emitter passage of the mask without penetration or structural modification of the mask. The voice transmission system is designed to receive a person's voice from a voice diaphragm located in the voice emitter passage of the mask, amplify the voice, and externally transmit the voice through the speaker.
