Abstract

A communications earpiece is disclosed which can be used by hearing impaired and non-hearing impaired users so as to be able to communicate with an external device such as personal communications node or cellular phone via a wireless link. A communications earpiece comprises an ear canal tube sized for positioning in an ear canal of a user so that the ear canal is at least partially open for directly receiving ambient sounds. A sound processor amplifies the received ambient sounds to produce a processed analog signal. The processed analog signal is then converted into digital signals and transmitted to a remote unit via a wireless link. The earpiece also receives signals from the remote unit which are then processed and applied to a speaker in the earpiece.

Claims

1. A communications earpiece, comprising:

an ear canal tube sized for positioning in an ear canal of a user so that the ear canal is at least partially open for directly receiving ambient sounds;

a sound processor for processing ambient sounds received by a microphone to produce processed signals;

means for transmitting said processed signals to at least one remote unit over a wireless link; and

means for receiving signals from said remote unit which are processed and applied to a speaker in said earpiece and broadcast into the ear canal by said ear canal tube.

2. A communications earpiece according to claim 1, wherein said remote unit is a personal communications node.

3. A communications earpiece according to claim 2, wherein said personal communications node includes means for manipulating signals to correct for hearing impairment.

4. A communications earpiece according to claim 2, wherein said personal communications node prevents feedback in said earpiece.

5. A communications earpiece according to claim 2, wherein said personal communications node can perform the operations of a two-way communications.

6. A communications earpiece according to claim 2, wherein said personal communications node connects to a two-way communications device so as to allow signals to pass between the earpiece and the two-way communications device.

7. A communications earpiece according to claim 6, wherein said personal communication node adjusts the gain of signals sent to said two-way communications device and received from said two-way communications device so that the personal communications node and said two-way communications device are compatible.

8. A communications earpiece according to claim 6, wherein said two-way communications device is a cellular phone.

9. A communications earpiece according to claim 1, wherein said remote unit is a two-way communications device.

10. A communications earpiece according to claim 1, further comprising:

a second ear canal tube, wherein a first end of said second ear canal tube is connected to the input of said microphone and a second end of said ear canal tube is open and is positioned near the ear canal, wherein ambient sounds enter said second end and propagate through the second ear canal tube to the input of the microphone.

11. A communications earpiece according to claim 1, wherein said speaker is located at one end of said first ear canal tube located in said ear canal and is electrically connected to said sound processor via wires in said first ear canal tube.

12. A communications earpiece according to claim 1, wherein said sound processor includes an analog-to-digital converter and wherein the transmitted processed signals are digital.

13. A communications earpiece according to claim 1, wherein said ambient sound is mixed with said signals from said remote unit in the ear canal of said user.

14. A communications earpiece according to claim 1, wherein said ear canal tube is at least partially open to directly pass ambient sound external of said ear canal to a tympanic membrane of the user.

15. A communications earpiece, comprising:

an ear canal tube sized for positioning in an ear canal of a user so that the ear canal is at least partially open for directly receiving ambient sounds;

a sound processor for processing ambient sounds received by a microphone to produce processed signals;

means for transmitting said processed signals to at least one remote unit over a wireless link;

means for receiving signals from said remote unit which are processed and applied to a speaker in said earpiece and broadcast into the ear canal by said ear canal tube; and

a second ear canal tube, wherein a first end of said second ear canal tube is connected to the input of said microphone and a second end of said ear canal tube is open and is positioned near the ear canal, wherein ambient sounds enter said second end and propagate through the second ear canal tube to the input of the microphone, wherein said second end is located in said ear canal.

16. A communications earpiece comprising:

an ear canal tube sized for positioning in an ear canal of a user so that the ear canal is at least partially open for directly receiving ambient sounds;

a sound processor for processing ambient sounds received by a microphone to produce processed signals;

means for transmitting said processed signals to at least one remote unit over a wireless link;

means for receiving signals from said remote unit which are processed and applied to a speaker in said earpiece and broadcast into the ear canal by said ear canal tube; and

a second ear canal tube wherein the microphone is located at one end of said second ear canal tube in said ear canal and is electrically connected to said sound processor via wires in said second ear canal tube.

17. A communications earpiece according to claim 16, wherein said speaker is located at one end of said first ear canal tube located in said ear canal and is electrically connected to said sound processor via wires in said first ear canal tube.

18. A communications earpiece, comprising:

a sound processor for processing ambient sounds received by a microphone to produce processed signals;

means for transmitting said processed signals to at least one remote unit over a wireless link; and

means for receiving signals from said remote unit which are processed and applied to a speaker in said earpiece and broadcast into the ear canal, said communications earpiece being configured for positioning in said ear of a user so that the ear canal is at least partially open for directly receiving ambient sounds.

19. A communications earpiece according to claim 18, wherein said remote unit is a personal communications node.

20. A communications earpiece according to claim 19, wherein said personal communications node includes means for manipulating signals to correct for hearing impairment.

21. A communications earpiece according to claim 19, wherein said personal communications node prevents feedback in said earpiece.

22. A communications earpiece according to claim 19, wherein said personal communications node can perform the operations of a two-way communications device.

23. A communications earpiece according to claim 19, wherein said personal communications node connects to a two-way communications device so as to allow signals to pass between the earpiece and the two-way communications device.

24. A communications earpiece according to claim 23, wherein said two-way communications device is a cellular phone.

25. A communications earpiece according to claim 24, wherein said personal communication node adjusts the gain of signals sent to said two-way communications device and received from said two-way communications device so that the personal communications node and said two-way communications device are compatible.

26. A communications earpiece according to claim 18, wherein said remote unit is a two-way communications device.

27. A communications earpiece according to claim 18, wherein said sound processor includes an analog-to-digital converter and wherein the transmitted processed signals are digital.
