ABSTRACT:
A microphone mounting structure for mounting a microphone to a respiratory mask and/or bubble suit through a hole therein. The microphone mounting structure is thus able to convert a conventional respiratory mask and/or bubble suit into a sound amplifying mask and/or bubble suit. The microphone mounting structure comprises a tubular plug 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 microphone is dimensioned so as to fit coaxially inside the tubular plug, and preferably, a grommet is provided around the microphone. 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 finger tips of the resilient fingers at which time the finger tips snap outwardly to thereby lock the microphone mounting structure to the respiratory mask/bubble suit. Amplification circuitry is also provided.
