Abstract

Claims (44)

1. A microphone coupler for a microphone located within a housing of a communication device, said coupler comprising:

a body section shaped to fit around said microphone, said body section having a port through a wall of said body section connecting to an internal cavity within said body section shaped to receive at least a portion of said microphone and to define a spaced relationship between said microphone and said body section;

a conduit having an internal channel therein, a distal end, a proximal end, a first opening in said distal end connecting to said internal channel and a second opening in said proximal end connecting to said internal channel; and

a support member connected to said conduit and attached to a location within said housing to provide a brace for conduit, wherein

for said conduit, said proximal end is connected to said body section and said second opening mates with said port; and said distal end extends towards a microphone opening in said housing.

2. The microphone coupler for a microphone as claimed in claim 1 , wherein said proximal end of said conduit is mateable with a side wall of said body section.

3. The microphone coupler for a microphone as claimed in claim 1 , wherein said conduit and said body section are formed as a single piece.

4. The microphone coupler for a microphone as claimed in claim 1 , wherein said conduit has a longitudinal length of between 10 mm and 15 mm.

5. The microphone coupler for a microphone as claimed in claim 1 , wherein said coupler is comprised of a plastic material.

6. A communication device for communicating signals in a wireless manner, said device comprising:

a housing;

a printed circuit board;

a microphone located within said housing on said printed circuit board;

an antenna located at least in part within said housing;

a microphone coupler for said microphone located within said housing, said coupler comprising:

a body section shaped to fit around said microphone, said body section having a port through a wall of said body section and an internal cavity within said body section shaped to receive at least a portion of said microphone and to define a spaced relationship between said microphone and said body section; and a conduit having an internal channel therein, a distal end, a proximal end, a first opening in said distal end connecting to said internal channel and a second opening in said proximal end connecting to said internal channel, wherein

said proximal end is connected to said body section and said second opening mates with said port; and

said distal end extends towards a microphone opening in said housing.

7. The communication device as claimed in claim 6 , wherein said antenna is located within said housing in a volume between said body section to said microphone.

8. The communication device as claimed in claim 6 , wherein said antenna is located in a bottom portion of said housing.

9. The communication device as claimed in claim 6 , wherein said microphone and coupler are located on a bottom side of said circuit board.

10. The communication device as claimed in claim 6 , wherein said conduit spans said volume, connecting said port with said microphone opening.

11. The communication device as claimed in claim 6 , further comprising an RF shield can for isolating said microphone from interference caused from signals associated with said antenna, said RF shield can located between said microphone and said coupler.

12. The communication device as claimed in claim 6 , further comprising a support member providing a brace for said conduit, said support member attached at one end to a location within said housing and at another end to said conduit.

13. The communication device as claimed in claim 6 , wherein keypad devices are located on a top side of said circuit board.

14. The portable communication device as claimed in claim 6 , further comprising a gasket located about said microphone providing a channel from said microphone to outside said RF shield can.

15. A communication device for communicating signals in a wireless manner, said device comprising:

a housing;

a printed circuit board;

a microphone located within said housing on said printed circuit board, said microphone having a port facing towards said circuit board and aligned with an opening through said circuit board;

an antenna located at least in part within said housing;

a microphone coupler for said microphone located within said housing, said coupler comprising:

a conduit having an internal channel therein, a distal end, a proximal end, a first opening in said distal end connecting to said internal channel and a second opening in said proximal end connecting to said internal channel, wherein

said proximal end is located about said opening of said circuit board and

said second opening is mated to said opening of said circuit board; and

said distal end extends towards a microphone opening in said housing.

16. The communication device as claimed in claim 15 , wherein said antenna is located within said housing in a volume between said conduit to said microphone and in a bottom portion of said housing.

17. The communication device as claimed in claim 15 , wherein:

said microphone is located on a bottom side of said circuit board;

said coupler is located on a top side of said circuit board; and

said coupler spans said volume, connecting said opening of said circuit board with said microphone opening.

18. The communication device as claimed in claim 15 , further comprising an RF shield can for isolating said microphone from interference caused from signals associated with said antenna.

19. The communication device as claimed in claim 15 , wherein keypad devices are located on a top side of said circuit board.

20. The microphone coupler for a microphone as claimed in claim 1 , wherein said body section is oblong in shape.
