Abstract

A system for two way communication under shallow water or between a swimmer and observer comprising a transceiver, a wire for conducting electrical signals connected to the transceiver, a watertight transducer housing that curvedly conforms to human heads incorporating a speaker/microphone transducer in watertight connection with the wire, an adjustable strap connected to the transducer housing so that it may be attached to a portion of a human body, and a hollow acoustic transmission tube in watertight connection with the transducer housing for sound transmission to an earplug which is inserted into a human ear.

Claims

1. An apparatus for two way communication comprising:

a transceiver, capable of sending and receiving radio signals of voice transmissions, said transceiver impervious to water;

a connecting line removably attachable to said transceiver, said connecting line forming a waterproof seal to said transceiver to prevent water leaking in, said connecting line capable of conducting electrical signals therethrough;

a speaker/microphone transducer removably connected to said connecting line, said speaker/microphone transducer capable of generating both electrical and acoustic signals;

a housing incorporating said speaker/microphone transducer in a watertight compartment, said housing having two external slots;

an adjustable strap by which to affix said housing to a portion of a human body, said adjustable strap attached to said housing through said external slots in said housing by loops with sliding buckles;

a hollow acoustical transmission tube connected to said housing for the transmission of acoustic signals therethrough, said hollow acoustical transmission tube being removably attachable to and forming a watertight seal with said housing; and

an earplug for the inserting into a human ear so that acoustical signals may be conducted therethrough, said earplug removably attachable to said hollow acoustic transmission tube and forming a watertight seal therewith and with the inner surface of said human ear, said earplug also capable of conducting acoustic signals from said human ear to said hollow acoustic transmission tube.
