Voice amplification adapter assembly for face mask
First Claim
1. A protective respirator, comprising:
- a face mask having an inhalation port through which a wearer of the mask inhales ambient air;
an air filter for filtering the inhaled ambient air and providing filtered air to said inhalation port;
a microphone assembly which is removably detachable from a location between said inhalation port and said air filter, said microphone assembly including a spacer for separating said filter from said inhalation port, said spacer having a body with a passage extending the entire length thereof through which filtered air may pass from said filter to said inhalation port, said spacer further having a microphone extending therefrom;
an amplifier connected to said microphone for receiving and amplifying sound transmitted by said microphone and outputting an amplified signal; and
a loudspeaker connected to said amplifier for receiving and radiating said amplified signal.

Abstract
A voice transmission system for a protective respirator, having a face mask with an inhalation port and a filter attached to the inhalation port, is provided. The voice transmission system comprises a microphone assembly adapted to be located between the inhalation port and the air filter, the microphone assembly including a spacer for separating the filter from the inhalation port and a microphone extending therefrom and into an interior space of the face mask, and a combined amplifier/loudspeaker assembly remotely connected to the microphone. The spacer of the microphone assembly provides an airtight seal between the filter and the face mask and includes a one-way inhalation valve. The spacer is provided with an outer surface configuration which matches the face mask on one side and the filter on another so that the microphone assembly may be attached intermediate the face mask and the filter without using any additional fasteners.
