Abstract

A wireless speakerphone with a pivoting microphone boom is provided. The speakerphone communicates via a wireless network to a cellular telephone, cellular telephone adaptor, land-line telephone, land-line telephone adaptor, computer, personal digital assistant, or other device capable of communicating via the wireless network. The microphone contained in the pivoting boom is a directional microphone, the design of the boom being such that the location of minimal microphone sensitivity is always directed towards the speakerphone'"'"'s speaker. The wireless speakerphone may also include an integral display, thereby allowing various types of system information to be displayed, aid speakerphone/system configuration and provide expanded speakerphone functionality.

Claims

1. A speakerphone comprising:

a housing;

a speaker mounted to said housing;

a unidirectional microphone;

a microphone boom pivotably coupled to said housing, said microphone boom capable of being placed at a plurality of positions, said unidirectional microphone mounted at a distal end of said microphone boom, wherein a region of said microphone having a lowest sensitivity is aimed at said speaker when said microphone boom is located in any of said plurality of positions; and

a wireless networking module adapted to transmit first signals via a short distance wireless network to a peripheral electronic device and to receive second signals via said short distance wireless network from said peripheral electronic device, wherein said first signals are initially received by said unidirectional microphone, and wherein said second signals are output by said speaker after receipt by said wireless network module.

2. The speakerphone of claim 1, wherein said peripheral electronic device forwards said first signals via a long distance communication network and wherein said second signals are transmitted to said peripheral electronic device via said long distance communication network.

3. The speakerphone of claim 2, wherein said long distance communication network is a cellular telephone network.

4. The speakerphone of claim 1, wherein said peripheral electronic device is a cellular telephone.

5. The speakerphone of claim 1, wherein said wireless networking module is a Bluetooth enabled networking module and said peripheral electronic device is a Bluetooth enabled cellular telephone.

6. The speakerphone of claim 1, wherein said wireless networking module is a Bluetooth enabled networking module and wherein said peripheral electronic device further comprises a Bluetooth enabled adaptor.

7. The speakerphone of claim 1, wherein said wireless networking module is an IEEE802.11 enabled networking module and said peripheral electronic device is an IEEE802.11 enabled cellular telephone.

8. The speakerphone of claim 1, wherein said wireless networking module is an IEEE802.11 enabled networking module and wherein said peripheral electronic device further comprises an IEEE802.11 enabled adaptor.

9. The speakerphone of claim 1, further comprising at least one status indicator.

10. The speakerphone of claim 1, further comprising a display means coupled to said housing.

11. The speakerphone of claim 10, wherein said display means is capable of displaying at least one of battery level, signal level, volume level, call status, speakerphone status, pairing status, caller identification, time, elapsed time, date, phone history, phone lists, and calendar.

12. The speakerphone of claim 10, wherein said display means is capable of displaying a text message.

13. The speakerphone of claim 10, wherein said display means is selected from the group of display means consisting of liquid crystal displays, light emitting polymer displays, electroluminescent displays, active matrix electroluminescent displays, organic thin film transistor displays, active matrix organic light emitting diode displays, amorphous silicon integrated displays, and pliable display technology displays.

14. The speakerphone of claim 1, further comprising a sound processor.

15. The speakerphone of claim 1, further comprising a portable power source.

16. The speakerphone of claim 15, further comprising means for coupling an external power source to said speakerphone.

17. The speakerphone of claim 1, further comprising means for coupling a mounting bracket to said housing.

18. The speakerphone of claim 1, further comprising a power switch.

19. The speakerphone of claim 1, further comprising a volume control.

20. The speakerphone of claim 1, wherein the microphone exhibits a cardioid polar pattern.

21. The speakerphone of claim 1, wherein the microphone is most sensitive to sound arriving from only one direction.

22. A speakerphone comprising:

a housing;

a speaker mounted to said housing;

a unidirectional microphone;

a sound processor coupled to said unidirectional microphone;

a portable power source coupled to said sound processor;

a microphone boom pivotably coupled to said housing, said microphone boom capable of being placed at a plurality of positions, said unidirectional microphone mounted at a distal end of said microphone boom, wherein a region of said microphone having a lowest sensitivity is aimed at said speaker when said microphone boom is located in any of said plurality of positions; and

a Bluetooth enabled networking module adapted to transmit first signals to a Bluetooth enabled cellular telephone and to receive second signals from said Bluetooth enabled cellular telephone.

23. The speakerphone of claim 22, wherein the microphone exhibits a cardioid polar pattern.

24. The speakerphone of claim 22, wherein the microphone is most sensitive to sound arriving from only one direction.
