Abstract

A method, system, and apparatus for an improved wireless headset configuration is provided. The apparatus is an open-air headset, which includes an ear attachment, a transceiver, a speaker, and a microprocessor. The headset further includes a directional microphone having a sensitivity field such that the sensitivity field is mutually exclusive from a non-sensitivity field, and is configured such that the speaker is placed in a region within the non-sensitivity field. The system further includes an audio gateway device, whereas the method includes the steps of transmitting a signal from an audio gateway device to the open-air wireless headset and receiving a signal from the headset into the audio gateway device.

Claims

1. A wireless headset comprising:

an ear attachment coupled to the body of an open-air headset;

a transceiver;

a speaker;

a microprocessor; and

a directional microphone having a sensitivity field, wherein said sensitivity field is mutually exclusive from a non-sensitivity field, and wherein said speaker is placed in a region within said non-sensitivity field.

2. The headset of claim 1, wherein said microphone is a bidirectional microphone such that said sensitivity field includes a first and second sensitivity field.

3. The headset of claim 2, wherein said first and second sensitivity fields are symmetrically opposed to each other.

4. The headset of claim 1, wherein said microprocessor includes a digital signal processor (DSP).

5. The headset of claim 4, wherein said DSP executes firmware that performs a real-time extraction of a signal received into said headset from a signal transmitted out of said headset.

6. A wireless headset comprising:

an ear attachment coupled to the body of an open-air headset;

a transceiver;

a speaker;

a microprocessor; and

a bidirectional microphone having a first sensitivity field, a second sensitivity field, and a non-sensitivity field, wherein said first sensitivity field, said second sensitivity field, and said non-sensitivity field are each mutually exclusive from each other, and wherein said speaker is placed in a region within said non-sensitivity field.

7. The headset of claim 6, wherein said first and second sensitivity fields are symmetrically opposed to each other.

8. The headset of claim 6, wherein said ear attachment is an ear hook.

9. The headset of claim 6, wherein said microphone is coupled to a vibration shield.

10. The headset of claim 6, wherein said microprocessor is adaptable to a Bluetooth communications protocol.

11. An wireless headset comprising:

an ear hook coupled to the body of an open-air headset;

a transceiver;

a speaker;

a microprocessor comprising a digital signal processor (DSP); and

a directional microphone having a sensitivity field, wherein said sensitivity field is mutually exclusive from a non-sensitivity field, and wherein said speaker is placed in a region within said non-sensitivity field.

12. The headset of claim 11, wherein said microprocessor is adaptable to a Bluetooth communications protocol.

13. The headset of claim 11, wherein said DSP executes firmware that performs a real-time echo-cancellation procedure.

14. The headset of claim 11, wherein said microphone is a bidirectional microphone such that said sensitivity field includes a first and second sensitivity field.

15. The headset of claim 14, wherein said first and second sensitivity fields are symmetrically opposed to each other.

16. A method for routing a wireless signal comprising:

transmitting a signal from an audio gateway device to an open-air wireless headset;

receiving a signal from said headset into said audio gateway device, wherein said headset comprises;

an ear attachment;

a transceiver;

a speaker;

a microprocessor; and

a directional microphone having a sensitivity field, wherein said sensitivity field is mutually exclusive from a non-sensitivity field, and wherein said speaker is placed in a region within said non-sensitivity field.

17. The method of claim 16, wherein said microphone is a bidirectional microphone such that said sensitivity field includes a first and second sensitivity field.

18. The method of claim 17, wherein said first and second sensitivity fields are symmetrically opposed to each other.

19. The method of claim 16, wherein said microprocessor is adaptable to a Bluetooth communications protocol.

20. The method of claim 16, wherein said microprocessor includes a digital signal processor (DSP).

21. A system for routing a wireless signal comprising:

an audio gateway device; and

an open-air wireless headset, wherein said headset comprises;

an ear attachment;

a transceiver;

a speaker;

a microprocessor; and

a directional microphone having a sensitivity field, wherein said sensitivity field is mutually exclusive from a non-sensitivity field, and wherein said speaker is placed in a region within said non-sensitivity field.

22. The system of claim 21, wherein said microphone is a bidirectional microphone such that said sensitivity field includes a first and second sensitivity field.

23. The system of claim 22, wherein said first and second sensitivity fields are symmetrically opposed to each other.

24. The system of claim 21, wherein said microprocessor is adaptable to a Bluetooth communications protocol.

25. The system of claim 21, wherein said microprocessor includes a digital signal processor (DSP).
