Abstract
A voice transmission system for a conventional gas mask or face mask includes an amplifier body and a remote microphone assembly. The amplifier body encloses an amplifier electronic components assembly, a speaker and one or more batteries, and is designed to be attached with a belt clip to the belt of a user. The microphone assembly is electrically connected by a flexible cord to the amplifier assembly and is designed to be removably coupled to the face mask. The microphone assembly includes a microphone and a microphone adapter. The microphone adapter includes a resilient mounting bracket which can be easily coupled to and uncoupled from the exhalation passage of the mask without penetration or structural modification of the mask such that the microphone is proximate a check valve in the exhalation passage of the mask. The microphone is designed to receive a person's voice through or around the check valve in the exhalation passage of the mask and communicate a signal to the amplifier assembly. The amplifier assembly then amplifies the voice signal, and the speaker externally transmits the signal.
