Abstract

A microphone unit positioned in one ear and including a microphone, noise cancellation tube and ear tube, and a headphone unit positioned in the other ear, together with a neck attachment unit around the wearer'"'"'s neck form an assembly for connecting to a communication device such as a cellular telephone while jogging or exercising. The microphone unit has a first movable joint for holding the first wire and the first noise cancellation tube and for controlling a length of slack of the first wire. The headphone unit includes an earphone cap, a second noise cancellation tube and a second movable joint for holding the second wire and second noise cancellation tube and for controlling a length of slack of the second wire. The neck attachment unit comprises a C-shaped holder that holds the first wire and the second wire and includes two swivel arms as grippers.

Claims

1. A headphone and microphone assembly for a cellular telephone comprising:

(i) a microphone unit that fits into a first ear of a user, the microphone unit including an ear tube, a first noise cancellation tube and a microphone that has a sensor,

the ear tube having a first end for receiving vibrations from the user'"'"'s body and a second end proximate to the sensor and positioned so that sound vibrations from the ear tube strike the sensor at a first angle, the first noise cancellation tube extending from the microphone to an open air, a proximal end of the first noise cancellation tube being at a cumulative angle to the ear tube and positioned at a second angle to the sensor to receive a noise remnant of the sound vibrations, the microphone connected by a first wire to a communication device,

the microphone unit including a first movable joint for holding the first wire and the first noise cancellation tube and for controlling a length of slack of the first wire, and

(ii) a headphone unit that fits into a second ear of the user, the headphone unit including an earphone cap and a speaker and having a second noise cancellation tube, the speaker connected to a communication device by a second wire, the headphone unit including a second movable joint for holding the second wire and second noise cancellation tube and for controlling a length of slack of the second wire, and

(iii) a neck attachment unit for wearing the assembly around the neck of the user and comprising a substantially C-shaped holder that holds the first wire and the second wire, the first and second wires entering opposing sides of the holder and exiting the holder at the central portion thereof, a first end of the C-shaped holder joined to a first swivel arm that further grips the user, and a second end of the C-shaped holder joined to a second swivel arm that further grips the user.

2. The assembly of claim 1, wherein at least one of the first and second noise cancellation tubes has an accordion-like cross-section with alternating larger and smaller sections of the tube.

3. The assembly of claim 1, wherein the ear tube has a series of elongated prongs to divide and reduce dissonant sound waves.

4. The assembly of claim 3, wherein the elongated prongs are substantially parallel to one another.

5. The assembly of claim 1, wherein at least one of the first and second noise cancellation tubes has an accordion-like cross-section with alternating larger and smaller sections of the tube and wherein the ear tube has a series of elongated prongs to divide and reduce dissonant sound waves.

6. The assembly of claim 1, wherein the first and second swivel arms are capable of swiveling outside a two-dimensional plane of the holder to extend between the user'"'"'s back and clothing.

7. The assembly of claim 1, wherein the first angle and the second angle are each approximately 45 degrees and wherein the cumulative angle is approximately 90 degrees.

8. The assembly of claim 1, wherein the first end of the ear tube of the microphone unit is designed to be positioned against an ear wall of the first ear.

9. The assembly of claim 2, wherein the first and second swivel arms are capable of swiveling outside a two-dimensional plane of the holder to extend between the user'"'"'s back and clothing.

10. The assembly of claim 1, wherein the ear tube includes an ear tube cap for fitting the ear tube into the first ear.
