Abstract

Claims (40)

1. A handheld, mobile communication device comprising:

a housing including a housing port;

a printed circuit board (PCB);

a microphone on the PCB in the housing;

circuitry in the housing and connected to the microphone;

a coupler including:

an acoustic conduit having a first end in communication with the housing port and a second end, and

a body section covering the microphone, contacting the PCB and being in communication with the second end of the acoustic conduit; and

a support connected to the acoustic channel to brace the coupler in the housing.

2. The mobile communication device of claim 1 , wherein the housing includes a bottom cover and the housing port is in the bottom cover.

3. The mobile communication device of claim 1 , wherein the housing includes an antenna adjacent the housing port.

4. The mobile communication device of claim 3 , wherein the antenna can send or receive information from a voice network or a data network.

5. The mobile communication device of claim 3 , wherein the housing includes a voice communication subsystem in communication with the microphone and the antenna.

6. The mobile communication device of claim 1 , wherein the body section defines an acoustic chamber adjacent the second end of the acoustic conduit.

7. The mobile communication device of claim 1 , wherein the acoustic conduit is plastic and the support is plastic.

8. The mobile communication device of claim 1 , wherein the body section covers the sides and top of the microphone.

9. The mobile communication device of claim 1 , wherein the body section includes a radio frequency shield around the microphone.

10. The mobile communication device of claim 9 , wherein the radio frequency shield includes an aperture to allow acoustic signals to the microphone.

11. The mobile communication device of claim 1 , wherein the body section includes an interior cavity.

12. The mobile communication device of claim 1 , wherein the coupler forms an air channel to the microphone from ambient surroundings outside the housing.

13. The mobile communication device of claim 12 , wherein the air channel includes a sealed acoustic chamber.

14. The mobile communication device of claim 1 , wherein the microphone is a silicon-based transducer.

15. The mobile communication device of claim 1 , wherein the acoustic conduit has an interior cross section of approximately 4 mm 2 .

16. The mobile communication device of claim 1 , wherein the acoustic conduit has a length of approximately 10 to 15 mm.

17. A mobile telephone comprising:

a housing forming a case with an acoustic port;

a printed circuit board (PCB);

an input device and supported by the housing;

an output device supported by the housing;

a communication subsystem in the housing;

a microphone located on the PCB and located in the housing;

an acoustic conduit, in the housing, having

a first end in communication with the acoustic port and a second end, and

a body, in the housing, covering the microphone, contacting the PCB and being in communication with the second end of the acoustic conduit; and

a support extending from the acoustic conduit and aligning the acoustic conduit in the housing.

18. The mobile telephone of claim 17 , wherein:

the output device is a display;

the microphone converts acoustic signals to electrical signals and sends the electrical signals to the communication subsystem;

the communication subsystem converts the electrical signal to a radio frequency signal and send the radio frequency signal to an antenna that is mounted in the housing, wherein the antenna is mounted in the housing; and

the body is affixed in the housing.
