Abstract

The present invention discloses a method and apparatus for hands free communication using a PDA. The method includes sensing a bone conduction signal from the bone conduction sensor disposed within an external auditory cannel of the user, transmitting the sensed bone conduction signal from a transmitter to a PDA, and processing the sensed bone conduction signal at the PDA to create a processed audio signal.

Claims

1. A method for hands free voice communications using a personal communications device comprising:

sensing a bone conduction signal from a bone conduction sensor fitted to the contours of a posterior superior wall of an external auditory canal of a user such that the posterior inferior wall of the external auditory canal remains unobstructed to allow ambient sound into the external auditory canal and to avoid an occlusive effect;

transmitting the sensed bone conduction signal from a transmitter to the personal communications device; and

processing the sensed bone conduction signal at the personal communications device to create a processed audio signal.

2. The method of claim 1 wherein the personal communications device includes a PDA.

3. The method of claim 1 further comprising transmitting the processed audio signal from the personal communications device over a cellular transceiver.

4. The method of claim 1 further comprising transmitting the processed audio signal from the personal communications device to a receiver disposed within an earpiece worn by the user;

and sending the processed audio signal from the receiver to a speaker disposed within the earpiece.

5. The method of claim 1 further comprising performing a yoke recognition function using the processed signal.

6. The method of claim 1 further comprising performing a voice activation function using the processed signal.

7. A method for hands free voice communications using a personal communications device comprising:

sensing an air conduction signal from an air conduction sensor nonocclusively disposed within an external auditory canal of a user such that at least one wall of the external auditory canal remains unobstructed;

sensing a bone conduction signed from a bone conduction sensor nonocclusively disposed within the external auditory canal of the user and positioned against a posterior superior wall of the external auditory canal;

transmitting the sensed air conduction signal and the sensed bone conduction signal from a transmitter located in an earpiece to a personal communications device; and

processing the sensed air conduction signal and the sensed bone conduction signal at the personal communications device to create a processed audio signal.

8. The method of claim 7 further comprising transmitting the processed audio signal from the personal communications device over a cellular transceiver.

9. The method of claim 7 further comprising transmitting the processed audio signal from the personal communications device to a receiver disposed within an earpiece worn by the user;

and sending the processed audio signal from the receiver to a speaker disposed within the earpiece.

10. The method of claim 7 further comprising performing a voice recognition function using the processed signal.

11. The method of claim 7 further comprising performing a voice activation function using the processed signal.

12. A method for hands free voice communications using a personal communications device comprising:

sensing an air conduction signal from an air conduction sensor proximate an external auditory canal of a user;

sensing a bone conduction signal from a bone conduction sensor fitted to a posterior superior wall of the external auditory canal of a user such that at least one wall of the external auditory canal remains unobstructed;

transmitting the air conduction signal and the bone conduction signal from a transmitter disposed within an earpiece to a personal communications device; and

processing the bone conduction signal and the air conduction signal at the personal communications device to create a processed audio signal.

13. The method of claim 12 wherein the air conduction sensor is in a position proximate the posterior superior wall of the external auditory canal and an opposite wall is unobstructed.

14. The method of claim 12 wherein the personal communications device includes a PDA.

15. The method of claim 12 further comprising transmitting the processed audio signal from the personal communications device over a cellular transceiver.

16. The method of claim 12 further comprising transmitting the processed audio signal from the personal communications device to a receiver disposed within an earpiece worn by the user;

and sending the processed audio signal from the receiver to a speaker disposed within the earpiece.

17. The method of claim 12 further comprising performing a voice recognition function using the processed signal.

18. The method of claim 12 further comprising performing a voice activation function using the processed signal.

19. A system for hands free voice communication using the processing capabilities of a personal communications device comprising:

an earpiece housing;

an air conduction sensor adapted to be nonocclusively disposed within an external auditory canal of a user and operatively connected to the earpiece housing and capable of transducing air conduction signals;

a bone conduction sensor adapted to be nonocclusively disposed within an external auditory canal of a user and operatively connected to the earpiece housing and capable of transducing bone conduction signals;
