Abstract
Abstract An acoustical-electrical transducer and support assembly is composed of an elongated tubular member which supports a microphone capsule of a condenser microphone at one end and the preamplifier of the microphone at the other end with electrical circuitry extending through the tubular member connecting the capsule and the preamplifier. A counterweight member is movably positionable on the end of the tubular member opposite the microphone capsule and incorporates the preamplifier. The tubular member and its attached parts are pivotally supported on a support member at the center of gravity of the assembly. In this arrangement the microphone capsule can be selectively positioned about the support member with its preamplifier disposed in a spaced nonobstructing location on the tubular member.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
222 words
An acoustical-electrical transducer and support assembly comprising a condenser microphone, said condenser microphone comprising a microphone capsule, a preamplifier, and electrical means connecting said microphone capsule and preamplifier, an elongated tubular member for supporting said condenser microphone, said microphone capsule secured to one end of said tubular member, a counterweight member adjustably positioned on said tubular member adjacent the opposite end thereof from said microphone capsule, said preamplifier mounted within said counterweight member, said electrical means connecting said microphone capsule and preamplifier extending through said tubular member and comprising a low-capacitance line, a support member for pivotally supporting said tubular member condenser microphone and counterweight membeR at the center of gravity thereof with a short section of said tubular member on which said counterweight is mounted extending from one side of said support member and a considerably longer section of said tubular member having said microphone capsule mounted on its end extending from the other side of said support member and the length of the longer section being a multiple of the length of the short section, so that a relatively small microphone capsule can be positioned on the end of a lightweight boomlike said tubular member for positioning the counterbalanced microphone capsule for sound pickup with its preamplifier spaced at the other end of said tubular member in a nonobstructing position.
Claim 2
Dependent Claim
222 words
An acoustical-electrical transducer and support assembly comprising a condenser microphone, said condenser microphone comprising a microphone capsule, a preamplifier, and electrical means connecting said microphone capsule and preamplifier, an elongated tubular member for supporting said condenser microphone, said microphone capsule secured to one end of said tubular member, a counterweight member adjustably positioned on said tubular member adjacent the opposite end thereof from said microphone capsule, said preamplifier mounted within said counterweight member, said electrical means connecting said microphone capsule and preamplifier extending through said tubular member and comprising a low-capacitance line, a support member for pivotally supporting said tubular member condenser microphone and counterweight membeR at the center of gravity thereof with a short section of said tubular member on which said counterweight is mounted extending from one side of said support member and a considerably longer section of said tubular member having said microphone capsule mounted on its end extending from the other side of said support member and the length of the longer section being a multiple of the length of the short section, so that a relatively small microphone capsule can be positioned on the end of a lightweight boomlike said tubular member for positioning the counterbalanced microphone capsule for sound pickup with its preamplifier spaced at the other end of said tubular member in a nonobstructing position.
Claim 3
Dependent Claim
29 words
An acoustical-electrical transducer and support assembly, as set forth in claim 1, wherein said counterweight member is a sleevelike member disposed about said tubular member and incorporating said preamplifier.
Claim 4
Dependent Claim
40 words
An acoustical-electrical transducer, as set forth in claim 1, wherein said support member is a fork-shaped bracket, and a pin extending through said tubular member and supported in said bracket for pivotally positioning said tubular member about said support member.
Claim 5
Dependent Claim
55 words
An acoustical-electrical transducer and support assembly, as set forth in claim 1, wherein a base member supports said support member, said base member comprises a heavily weighted plate and a layer of resilient material secured to the lower surface of said plate and arranged to contact the supporting surface on which said assembly is positioned.
