Abstract

A system of wearable or personal area devices includes a first earpiece and a second ear piece each of the first ear piece and the second ear piece comprising an ear piece housing, an induction circuit disposed within the ear piece housing for short range communications, and a radio transceiver disposed within the ear piece housing for radio communications. The induction circuit of the first ear piece and the induction circuit of the second ear piece are adapted for communication there between using high bandwidth audio.

Claims

1. A set of earpieces, comprising:

a first earpiece comprising;

(a) a first earpiece housing, wherein the first earpiece housing is watertight;

(b) an induction circuit disposed within the first earpiece housing for short range communication of high bandwidth audio, wherein the induction circuit is a near field magnetic induction circuit;

(c) a radio transceiver disposed within the first earpiece housing for radio communications;

(d) a speaker disposed within the first earpiece housing;

(e) an intelligent control disposed within the first earpiece housing, the intelligent control operatively connected to the induction circuit, the radio transceiver and the speaker;

(f) an emitter and a detector operatively connected to the intelligent control for receiving user input; and

(g) a solid state memory operatively connected to the intelligent control for storing one or more audio files; and

a second earpiece comprising;

(a) a second earpiece housing, wherein the second earpiece housing is watertight,

(b) a speaker disposed within the second earpiece housing; and

(c) an induction circuit disposed within the second earpiece housing for short range communication with the first earpiece wherein the induction circuit is a near field magnetic induction circuit, wherein the high bandwidth audio received from the first earpiece induction circuit is greater than 10 kHz with less than 3 dB loss.

2. The system of claim 1, wherein the radio transceiver is a Bluetooth radio transceiver.

3. The system of claim 1, further comprising a mobile device in operative communication with the first earpiece via the radio transceiver disposed within the earpiece housing of the first earpiece.

4. The system of claim 1, further comprising at least one microphone with a frequency response suitable for ambient sounds.

5. The system of claim 4, wherein the at least one microphone can pick up sounds well above the 7 kHz or so associated with the vocal range.

6. The system of claim 5, wherein the first earpiece housing forms a barrier between the at least one microphone and the speaker.

7. The system of claim 6, wherein the at least one microphone captures unmodified environmental sounds on one side of the barrier and the speaker reproduces the environmental sounds for the user at an opposite side of a barrier formed by earpiece housing.

8. An earpiece comprising:

an earpiece housing, wherein the earpiece housing is watertight;

a near field magnetic induction circuit disposed within the earpiece housing for short range communication, wherein the near field magnetic induction circuit within the earpiece is adapted for communications using a high bandwidth audio of greater than 10 kHz and less than 20 kHz with less than 3 dB loss;

a Bluetooth transceiver disposed within the earpiece housing for radio communications;

at least one microphone disposed with the earpiece housing, wherein the at least one microphone is configured to allow environmental sounds to be captured;

a speaker disposed within the earpiece housing, wherein the speaker reproduces the environmental sounds captured by the at least one microphone;

an intelligent control disposed within the earpiece housing, the intelligent control operatively connected to the near field magnetic induction circuit, the radio transceiver, the speaker and the at least one microphone;

an emitter and a detector operatively connected to the intelligent control for receiving user input; and

a solid state memory operatively connected to the intelligent control for storing one or more audio files.

9. The earpiece of claim 8, further comprising a battery disposed within the earpiece, the battery operatively connected to the intelligent control and the radio transceiver.

10. A method for communication between a set of earpieces, comprising the steps of:

receiving ambient or environmental sound at at least one microphone operatively coupled to a first or a second earpiece housing;

communicating information between a first earpiece and a second earpiece using an induction circuit of the first earpiece and an induction circuit of the second earpiece; and

reproducing the information in an audible form by a speaker operatively coupled to the second or the first earpiece housing;

wherein the induction circuit disposed within the earpiece housing for short range communication uses high bandwidth audio of between 10 kHz and 20 kHz bandwidth with less than a 3 dB loss.

11. The method of claim 10, further comprising the steps of combining the step of combining the ambient or the environmental sound with an audio stream with a processor operatively coupled to the at least one microphone within the first or the second earpiece housing.

12. The method of claim 11, further comprising the step of processing the information to be sent between the first earpiece and the second earpiece.

13. The method of claim 12, further comprising the step of storing the audio stream within a memory operatively coupled to the processor within the first or the second earpiece housing.

14. The method of claim 13, further comprising the step of communicating with a mobile device through a radio transceiver operatively coupled to the processor within the first earpiece housing.

15. The method of claim 14, wherein the induction circuit disposed within the earpiece housing for short range communication uses high bandwidth audio of between 12 kHz and 20 kHz bandwidth with less than a 3 dB loss.

16. The method of claim 15, wherein the first and the second earpiece housing act as a barrier between the at least one microphone and the speaker.
