Abstract

An improved portable voice communication device is provided which comprises a speaker-microphone unit having a transducerspeaker disposed in a sealed housing and an elongated acoustical pick-up tube and an ear funnel communicating with opposite sides of the speaker and projecting from the housing. A radio transceiver is disposed in a second separate housing. The transceiver'"'"''"'"'s signal converting section is electrically linked to the speaker-microphone unit through an elongated cable. Anchoring means attached to the exterior of the first housing adjacent the ear funnel cooperate therewith for releasably securing that housing in place adjacent the ear and mouth of the user on a helmet or headpiece. Pivoting or other movement of the first housing relative to the support device is prevented by the projecting ear funnel which engages an opening on the headwear.

Claims

1. a transducer;

2. The improved device of claim 1 wherein said acoustical pick-up tube is in communication with one side of said transducer and said ear funnel is in communication with the opposite side of said transducer.

3. a first hollow housing enclosing said transducer, from which housing said pick-up tube extends;

4. The improved device of claim 1 wherein said headwear comprises a helmet.

5. anchoring means attached to the exterior of said housing adjacent said ear funnel for releasably securing said unit adjacent the ear of the user;

B. a radio transceiver disposed within a second separate housing; and

C. an elongated cable means electrically linking said transducer and the signal converting portion of said radio transceiver, said anchoring means including headwear defining an aperture releasably receiving said funnel and also including snap means releasably cooperatively engaged on the exterior of said headwear and said first housing, to prevent pivoting of said first housing relative to said headwear.

6. The improved device of claim 1 wherein said headwear comprises a head set.

7. The improved device of claim 2 wherein said transceiver comprises a walkie-talkie unit and wherein said funnel is coaxial with said transducer.

8. The improved device of claim 7 wherein said cable electrically by-passes the portion of said walkie-talkie unit.

9. A portable voice communication device comprising:

a unitary transducer mounted in a sealed housing so as to establish two separate chambers on opposite sides of the transducer;

a hollow ear funnel extending through the housing wall from one said chamber at a point next to the transducer;

an elongated hollow tube extending through the housing wall from the other chamber and coupled to an acoustical pick-up, said tube being supported by the housing and in turn supporting the pick-up in position adjacent a user'"'"''"'"'s mouth when the ear funnel is in line with and adjacent a user'"'"''"'"'s ear;

means electrically coupling the transducer with the input and output of an associated ratio transceiver; and

anchoring means attached to the exterior of said housing adjacent said ear funnel, said anchoring means including headwear defining an aperture releasably receiving said funnel and also including snap means releasably cooperatively engaged on the exterior of said headwear and said housing to prevent pivoting of said housing relative to said headwear.

10. The device of claim 9 further including adjustable support means extending along at least a portion of said hollow tube and adapted to maintain the shape of said tube as adjusted by the user in order to support the pick-up in a selected position adjacent the user'"'"''"'"'s mouth.

11. The device of claim 10 wherein the support means comprises a relatively rigid wire extending within the tube and affixed at one end to the housing, said wire being sufficiently pliant to be manually adjustable as to the shape thereof along its length.
