    (b) said first housing defining a sound inlet portion in said top portion, said microphone being positioned adjacent said sound inlet portion, whereby said first person is able to speak into said microphone through said inlet portion;

    (c) said first housing further including a DC battery power source for providing power for said microphone and amplifier, said microphone and amplifier being electrically interconnected so as to detect sound and amplify the same;

    (d) said first housing including a switch for manually switching said communication apparatus on and off, said switch further being adapted for regulating the amount of amplification by said communication apparatus;

    (e) a second housing separate and distinct from said first housing, said second housing being constructed and arranged to fit over the ear of said second person, said second housing having a U-shaped configuration and being necessarily configured for carrying on the body of said first person, said U-shaped second housing having a side wall and flexible edge walls extending perpendicular to the side wall and extending along the sides and top of said sidewall, the edge walls and side wall defining a cavity for placement of the ear, said second housing having means for receiving electrical signals from said amplifier, and for converting said electrical signals into sound waves;

    (f) an electrical connector electrically connecting said receiving means in said second housing with said amplifier in said first housing, whereby the voice of said first person is amplified and transmitted to said means in the second housing, thereby enabling the second person to hear the first person, said second housing including a pivotal adaptor for interconnecting said electrical connector thereto; and
