Claims
- 1. A two-way voice communication device comprising:
a receiver for transducing a first electrical signal into sound; an ear tip for insertion into an ear canal of a user, the ear tip, upon insertion into the ear canal, securing the device in an operable position on the head of the user without requiring use of additional attachment to the user, the ear tip providing a reduction of external acoustic noise of at least 7 dB; and a microphone for transducing speech of the user into a second electrical signal.
- 2. The two-way voice communication device of claim 1 wherein the reduction of external acoustic noise comprises 19 dB.
- 3. The two-way voice communication device of claim 1 further comprising a boom for supporting the microphone.
- 4. The two-way voice communication device of claim 3 wherein the boom may be deformed in order to place the microphone nearer the mouth of the user.
- 5. The two-way voice communication device of claim 1, further comprising a switch for canceling the second electrical signal.
- 6. The two-way voice communication device of claim 1, further comprising a switch supporting a push-to-talk mode of operation.
- 7. The two-way voice communication device of claim 1 further comprising a radio frequency receiver for demodulating a first radio frequency signal into the first electrical signal.
- 8. The two-way voice communication device of claim 1 further comprising a radio frequency transmitter for transmitting a second radio frequency signal, wherein the second radio frequency signal is modulated to carry the second electrical signal.
- 9. The two-way voice communication device of claim 7 or claim 8 wherein the radio frequency communication is compliant with the Bluetooth radio frequency communication standard.
- 10. The two-way voice communication device of claim 1 further comprising a cable having a plurality of electrical conductors for carrying at least the first and second electrical signals, the cable having a first end and a second end, the first end attached to the earphone and the second end for connection to an electrical audio device.
- 11. The two-way voice communication device of claim 10, wherein the cable has a coiled portion nearest the first end for reducing the audible effects of physical contact of objects with the cable.
- 12. The two-way voice communication device of claim 10 wherein the cable further comprises a switch for canceling the second electrical signal.
- 13. The two-way voice communication device of claim 10 wherein the cable further comprises a switch supporting a push-to-talk mode of operation.
- 14. The two-way voice communication device of claim 1 further comprising:
a second receiver for transducing a third electrical signal into sound; and a second ear tip for insertion into a second ear canal of a user.
- 15. The two-way voice communication device of claim 14 wherein the first electrical signal and the third electrical signal are the same signal.
- 16. A two-way voice communication device comprising:
a receiver for transducing a first electrical signal into sound; an ear piece for transmitting the sound into the ear canal of a user; a microphone for transducing speech of the user into a second electrical signal; and a cable for carrying at least the first and second electrical signals, the cable having a coiled portion nearest an end proximate the ear piece for reducing the audible effects of physical contact of objects with the cable.
- 17. The two-way voice communication device of claim 16 further comprising a boom for supporting the microphone.
- 18. The two-way voice communication device of claim 17 wherein the boom may be deformed in order to place the microphone nearer the mouth of the user.
- 19. The two-way voice communication device of claim 16 further comprising a switch for canceling the second electrical signal.
- 20. The two-way voice communication device of claim 16 further comprising a switch supporting a push-to-talk mode of operation.
- 21. A two-way voice communication device comprising:
a receiver for transducing a first electrical signal into sound; an ear tip for insertion into an ear canal of a user, the ear tip, upon insertion into the ear canal, securing the device in an operable position on the head of the user without requiring additional attachment to the user; a microphone for transducing speech of the user into a second electrical signal; and the device providing a reduction of external acoustic noise of greater than 7 dB.
- 22. The two-way voice communication device of claim 21 wherein the reduction of external acoustic noise comprises 19 dB.
- 23. The two-way voice communication device of claim 21 further comprising a boom for supporting the microphone.
- 24. The two-way voice communication device of claim 21 further comprising a radio frequency receiver for demodulating a first radio frequency signal into the first electrical signal.
- 25. The two-way voice communication device of claim 21 further comprising a radio frequency transmitter for transmitting a second radio frequency signal, wherein the second radio frequency signal is modulated to carry the second electrical signal.
