Abstract
A voice transmission system for a protective face mask is provided, comprising a voice transmitter attached to an external portion of the face mask, a radio receiver, and a two-way radio. The voice transmitter is attached to an external portion of the face mask and transmits the voice of a user of the face mask via a short range radio signal. The radio receiver receives the short range radio signal output by the voice transmitter, processes the short range radio signal, and outputs an audio output signal. The two-way radio (i) receives the audio output signal from the radio receiver, amplifies the audio output signal, and transmits the amplified audio output signal to a remotely located receiver, in a transmitting mode, and (ii) receives a broadcast signal from a remotely located transmitter in a receiving mode. A voice actuated switch switches the two way radio between receiving and transmitting modes. The transmitter transmits the short range radio signal in the ultra high frequency (UHF) radio range, and the receiver downconverts the short range radio signal from the UHF radio range to the audio frequency range.
