A Small Unidirectional Dynamic Probe Microphone
This paper describes a unidirectional dynamic microphone of small size utilizing the -uniphase- system. Under idealized conditions the elements of the phase shift network employed can be shown to be functions of the independent variables: (a) the inertance of the back entry, (b) its resistance and (c) the distance of the two sound-entries. Under real conditions certain modifications of the phase shift network are necessary; these are described as is a partially laminated Mylar diaphragm used.
