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.
