Ear microphone apparatus and method
First Claim
1. An earset, comprising:
- a housing positionable with respect to an ear of a person;
a microphone disposed with respect to the housing for insertion into the ear of a person, the microphone operable to detect a change in air pressure within the ear while the person speaks and to produce an electrical microphone signal corresponding to the internally detected change in air pressure;
a speaker disposed with respect to the housing and operable to produce a sound corresponding to an electrical speaker signal; and
a circuit coupled to receive the microphone signal and the speaker signal and operable to produce a corrected microphone signal having a reduced feedback component of the microphone signal, the feedback component resulting from the detection by the microphone of the sound produced by the speaker to produce a corrected microphone signal.

Abstract
An earset including a housing positionable with respect to an ear of a person, a microphone disposed with respect to the housing for insertion into the ear of a person, the microphone operable to detect a change in air pressure within the ear while the person speaks and to produce an electrical microphone signal corresponding to the internally detected change in air pressure and a speaker disposed with respect to the housing and operable to produce a sound corresponding to an electrical speaker signal. The earset also includes a circuit coupled to receive the microphone signal and the speaker signal and operable to produce a corrected microphone signal having a reduced feedback component of the microphone signal, the feedback component resulting from the detection by the microphone of the sound produced by the speaker to produce a corrected microphone signal.

11. A method of detecting speech of a person, comprising the steps of:
-
placing a microphone at least partially within an ear of the person;
detecting a change in air pressure within the ear of the person using the microphone, the change in air pressure corresponding to the speech of the person;
producing an electrical microphone signal corresponding to the internally detected change in air pressure;
placing a speaker with respect to the ear of the person;
generating a sound with the speaker corresponding to an electrical speaker signal; and
generating a corrected microphone signal by reducing a feedback component of the microphone signal, the feedback component resulting from the detection by the microphone of the sound generated by the speaker to produce a corrected microphone signal. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
