  • Patent number: 6430298
    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 is tubular plug, and preferably, a grommet is provided around the microphone.
