Microphone Adaptor For Altering The Geometry Of A Microphone Without Altering Its Frequency Response Characteristics
US Patent:
8116499, Feb 14, 2012
Filed:
Jan 23, 2009
Appl. No.:
12/321624
Inventors:
John Grant - Baltimore MD, US

Antonino Correlli - Baltimore MD, US
International Classification:
H04R 1/38
US Classification:
381358, 381351, 381360, 381361, 381366
Abstract:
A method of improving the “tight space” usefulness of a unidirectional microphone of the type having an otherwise screw-together headpiece and handle, includes the steps of: (a) fabricating an adapter having male- and female-threaded ends and a cavity of a specified volume that extends between these ends, and where each of these ends has a centerline and these intersect at a prescribed angle, (b) fabricating the adapter's cavity so that its volume is approximately equivalent to that of the volume of handle's acoustic chamber, and (c) connecting the adapter's male-threaded end to the handle and its female-threaded end to the headpiece in such a manner as to not appreciably change the frequency response characteristics of the microphone.
