Abstract

Disclosed, in general, are devices that provide a substantially active noise canceling area over a sound source by causing disruptive interference to all frequency fields of speech sounds from the sound source. In some embodiments, active noise control or active noise cancellation means (“ANC means”) are provided to the device. Said means include one or more active noise canceling speakers for the addition of sound specifically designed to cancel noise from the speech sound source without interfering with the sound source going to the microphone, so the listener can clearly hear what the user is saying.

Claims

1. A telephone headset comprising:

a support arm that defines a telephone component housing;

at least a mouthpiece disposed at a first end of the support arm, said mouthpiece positioned adjacent to a mouth of a user, said mouth piece featuring a plurality of active noise canceling speakers and a microphone for receiving sounds to be telecommunicated, wherein said microphone for receiving sounds is directed toward said mouth of the user, and wherein said plurality of active noise canceling speakers are configured to destructively envelop sound from said mouth by the provision of antiphase sound in an area around said mouth via broadcasting antiphase noise in directions that are away from said mouth of the user and toward the face of the user;

an ear chamber disposed at a second end of the support arm with an ear opening for engaging the ear of a user;

a speaker, disposed within the component housing and configured to communicate sound into the ear chamber;

means for receiving and transmitting a telephonic or other electronic communication disposed within the component housing, said means electronically coupled to said speaker, said microphone, and said noise canceling means.

2. The headset of claim 1 wherein the support arm is configured so that the ear chamber engages the ear of a user while the mouth piece simultaneously resides in front of the mouth of a user.

3. The headset of claim 2 wherein the support arm is supported between the ear piece and mouth piece so that said arm is positioned along the jaw of a user when worn at a metocervical angle in a range of fifteen and twenty five degrees.

4. The headset of claim 3 wherein the support arm is supported between the ear piece and mouth piece so that said arm is positioned along the jaw of a user when worn at a metocervical angle of about nineteen degrees for female users and about twenty three degrees for male users.

5. The headset of claim 1 wherein a circuit board is disposed within the support arm, wherein the circuit board is further defined by

a female jack, wherein the female jack receives a lever operated quick disconnect male jack,

a mechanical switch defined by a physical switch, whereby the physical switch moves when a registered jack phone cord is inserted into the female jack, and

a mechanical physical analog to digital and then digital to analog sensing switch.

6. The headset of claim 5, wherein the circuit board:

determines voltage levels used for a speaker and the bias voltage in a microphone;

gathers the information from a-sensor;

determines which signal is present in at least one wire; and

activates a switch to create a route for audio and voltage signals, whereby the headset may be employed with different land line wiring configurations.

7. A method of privately communicating comprising the steps of:

obtaining a telephone headset comprising—

a support arm,

a mouthpiece disposed at a first end of the support arm, said mouthpiece featuring a plurality of active noise canceling speakers and a microphone for receiving sounds to be telecommunicated, wherein said microphone for receiving sounds is directed toward said mouth of the user, and wherein said plurality of active noise canceling speakers are configured to destructively envelop sound from said mouth by the provision of antiphase sound in an area around said mouth via broadcasting antiphase noise in directions that are away from said mouth of the user and toward the face of the user,

an ear chamber disposed at a second end of the support arm with an ear opening for engaging the ear of a user;

simultaneously positioning the mouth opening in front of the mouth of a user and engaging the ear opening with an ear respectively; and

,

communicating via the mouth so that air is received over the mouthpiece and sound energy is destructed via antiphase noise from the noise canceling means.

8. The method of claim 7 wherein the arm is supported between the ear piece and mouth piece so that said arm is positioned along a jaw at a metocervical angle in a range of fifteen and twenty five degrees after the step of simultaneously engaging the mouth opening and ear opening with a mouth and ear respectively.

9. The method of claim 8 wherein the metocervical angle is about nineteen degrees for female users.

10. The method of claim 9 wherein the metocervical angle is about twenty three degrees for male users.
