摘要：
A microphone module for non-invasive ventilation mask includes a microphone housing that defines and adapter configured to be removably inserted into a port of a non-invasive ventilation mask and form a seal with the port. The microphone module includes microphone elements for generating a speech signal and electrical circuitry for transmitting the mic signal to a cable outside the mask. A microphone system includes an audio processing system and the microphone module connected through a cable. The audio processing system receives the speech signal, amplifies the speech signal and outputs the amplified signal to a loudspeaker.
