ABSTRACT:
A device for talking underwater comprising a body made of a rigid material with a large opening and a small opening. The large opening has a thin diaphragm cover and the small opening has a mouth fitting for forming an airtight seal around a users mouth. Speaking into the device through the mouth fitting sends sound waves to the diaphragm which transmits the sound vibrations to the water. One-way blow valves in the side of the body allow exhaled air to escape while speaking into the device. The blow valves do not allow water to enter the body. The blow valves are constructed such that bubbles released to the surrounding water are too small to produce excessive amounts of disruptive noise. The body is preferably cone-shaped, but can be any shape, provided it has large and small openings.
