Integrated diver face mask and ultrasound underwater voice communication apparatus
First Claim
1. An integrated diver'"'"'s face mask and ultrasound underwater communication apparatus having, in combination with the face mask, a pair of adjacent first and second enclosures integrally connected transversely along and to the top of the mask, the first enclosure containing ultrasound frequency transmitting-receiving electronics and the second containing a battery power supply, with an ultrasound transducer provided at the forward end of the first enclosure;
- earphone means connected at the sides of the mask integrally therewith and exposed inwardly thereof;
microphone means supported near the lower portion of the mask within the same and on one side thereof; and
electrical connections laid along the mask surfaces to interconnect the microphone to the transmitting electronics and the earphones to the receiving electronics in the first enclosure, and the said transmitting-receiving electronics in the first enclosure to the battery power supply in the second enclosure; and
the microphone means being provided with means for responding to the diver'"'"'s voice sounds within the face mask while substantially cancelling ambient mask vibrations produced by bubbles, air regulation, and breathing sounds.

8. An underwater communication apparatus having, in combination, a waterproof microphone comprising a pair of spaced inner and outer piezoelectric surfaces facing in opposite directions so as to be mechanically out-of-phase, the inner surface facing inwardly to receive voice sounds and both surfaces receiving ambient vibrations from bubbles and air regulation;
- means for electrically connecting the surfaces in phase to receiving electronics such that the voice sounds transduced into electrical signals by the inner surface are fed to the receiving electronics, but vibrations are transduced by both surfaces into opposite substantially cancelling electrical signals.
