In the ear auxiliary microphone for behind the ear hearing prosthetic
First Claim
1. An apparatus for use with a Behind The Ear (BTE) Implantable Cochlear Stimulation (ICS) system, the BTE including a removable earhook and the ICS system including a speech processor, the apparatus comprising:
- a microphone assembly, wherein the microphone assembly includes a microphone which converts audio sounds into electrical signals which are processed by the speech processor to generate signals provided to an implantable circuit adapted to generate electrical pulses to stimulate nerves in the cochlea;
means for positioning the microphone assembly to receive sound waves through a port, wherein the sound waves are directed from a volume between a user'"'"'s ear and the earpiece of a communications handset held to the ear; and
means for electrically connecting the microphone to the speech processor, wherein the positioning means includes a first end attached to the earhook and a second end directed towards the inside of a user'"'"'s ear, wherein the microphone assembly is attached to the second end of the positioning means.

Abstract
An In The Ear (ITE) microphone which converts audio sounds into electrical signals which are then processed by a speech processor to generate electrical pulses to stimulate nerves in the cochlea, improves the acoustic response of a Behind The Ear (BTE) Implantable Cochlear Stimulation (ICS) system during telephone use. An acoustic seal provided by holding a telephone earpiece against the ear provides improved coupling of low frequency (up to about 1 KHz) sound waves, sufficient to overcome losses due to the near field acoustic characteristics common to telephones. In an exemplary embodiment, the ITE microphone is connected to a removable ear hook of the BTE ICS system by a short bendable stalk.
