Method and apparatus for tooth bone conduction microphone
First Claim
Patent Images
1. A two-way tooth microphone communication apparatus comprising:
- a sound transducer element directly in contact with at least one tooth in a user'"'"'s mouth, said transducer producing an electrical signal in response to speech by a user in a high ambient noise environment;
a first transceiver module transmitting said electrical signal to an external apparatus, external apparatus in proximity to said user;
a second transceiver module in said external apparatus retransmitting said electrical signal to a second user.

Abstract
A two-way communication system particularly valuable for noisy environments where a user has a tooth bone conduction microphone in his mouth normally controlled by a tongue switch that transmits an electrical signal representing speech to a retransmit module usually worn on the user'"'"'s body or mounted on an earphone or headset where the speech electrical signal is retransmitted to a second user usually by RF. The retransmit module can also receive signals from the second user and transmit them to the earphone or headset thus providing two-way communication.

8. A method for two-way tooth microphone communication apparatus in a noisy environment comprising:
- placing a sound transducer element in a first user'"'"'s mouth, said sound transducer element directly in contact with at least one of said first user'"'"'s teeth, said sound transducer producing an electrical signal representative of speech by said user in a high ambient noise environment;
coupling an RF transmitter to said sound transducer element so that said electrical signal is transmitted to a retransmission module;
causing said retransmission module to retransmit said electrical signal to a remote station. - View Dependent Claims (9, 10, 11)
- placing a sound transducer element in a first user'"'"'s mouth, said sound transducer element directly in contact with at least one of said first user'"'"'s teeth, said sound transducer producing an electrical signal representative of speech by said user in a high ambient noise environment;
- 12. A two-way tooth microphone communication apparatus for capturing speech in a noisy environment comprising a tooth bone microphone directly in contact with at least one tooth in a user'"'"'s mouth, said tooth bone microphone producing an electrical signal representative of speech by said user in a high ambient noise environment, said electrical signal being transmitted to a module exterior to said user'"'"'s mouth, said module retransmitting said electrical signal to a remote station.
