ABSTRACT:
A microphone mounting structure for mounting a microphone to a respiratory mask through a hole in the respiratory mask. The microphone mounting structure is thus able to convert a conventional respiratory mask into a sound amplifying respiratory mask. The microphone mounting structure comprises a tubular plug, a sleeve, and a tubular locking mechanism. The tubular plug has a closed end, an open end and a central portion disposed therebetween. The closed end of the tubular plug has a larger outer diameter than an outer diameter of the central portion. The open end has a plurality of resilient fingers defined by slots in the open end, the resilient fingers having finger tips which project radially outwardly with respect to the tubular plug. The sleeve receives the microphone and is dimensioned so as to fit coaxially inside the tubular plug. The tubular locking mechanism has an inner diameter substantially equal to the outer diameter of the central portion and a longitudinal length slightly shorter than a combination of the central portion and the open end. Accordingly, the tubular locking mechanism is slidable over the resilient fingers after the tubular plug is inserted through the hole in the mask. This forces the resilient fingers radially inwardly until the entire tubular locking mechanism has passed over the fingers tips of the resilient fingers at which time the finger tips snap radially outwardly to thereby lock the microphone mounting structure to the respiratory mask. Amplification circuitry is also provided.
