First Claim
Patent Images
1. An ear microphone comprising:
- a pickup piece of rigid material having a first portion configured for mating with a human external auditory canal;
means for converting bone-conducted voice vibrations from said auditory canal into electrical signals, said converting means being installed within the pickup piece;
resilient means attached to a second portion of said pickup piece, said resilient means having a resiliency greater than said pickup piece and a mass less than said pickup piece;
a rigid support body having a mass greater than and resiliency less than said resilient means and attached to said resilient means for supporting the pickup piece and the resilient means and adapted to extend outside the human external auditory canal while in use whereby the pickup piece, the resilient means, and the support body are arranged in a sandwich structure for reducing noise generated due to external vibrations on the ear microphone; and
said converting means having a converter lead wire means extending through the pickup piece, the resilient means and the support body for signal processing purposes.

Abstract
An ear microphone comprising a pickup piece having a configuration which facilitates insertion thereof into a human external auditory canal, a vibration/electrical signal converter element installed within the pickup piece, a resilient member attached to the pickup piece, and a support body to support the pickup piece by way of the resilient member. The pickup piece and support body are of a rigid material having a large mass whereas the resilient member has a large resiliency. The converter element has a lead wire extending therefrom through the pickup piece, the resilient member, and the support body for signal processing outside the ear microphone.
