摘要： A microphone system includes a microphone and a pre-amplification conditioning circuit configured within a housing and comprising a pair of matched JFETs configured in a differential pair with common-source configuration and, when biased, are operable to receive and amplify the differential microphone output signal. The microphone further includes a pair of BJTs configured as a complimentary feedback transistor pair with each of the pair of BJTs coupled in parallel to a corresponding one of the pair of matched JFETs, and a current sink coupled to the matched JFETs and corresponding emitter electrodes of the BJTs and operable to maintain a fixed total direct current through each of the matched JFETs and BJTs, which reduces the JFETs corresponding electrical load, reduces signal noise, and increases a maximum amplified microphone output signal level at the drains of the matched JFETs.

摘要： A microphone capsule assembly includes a first microphone capsule oriented to face a first direction that is parallel to a first plane, a second microphone capsule oriented to face in a direction opposite to the first direction, where a front face of the second microphone capsule is spaced a distance from a front face of the first microphone capsule in the first direction, a third microphone capsule oriented to face in a second direction that is at a first acute angle to the first direction when measured parallel to the first plane, and a fourth microphone capsule oriented to face in a third direction that is at a second acute angle to the first direction when measured parallel to the first plane, where the third and fourth microphone capsules are spaced a distance from the front face of the first microphone capsule in the first direction.

摘要： A microphone includes a housing. The microphone includes a windscreen coupled with the housing. The windscreen and the housing define a central volume. The microphone includes an audio module within the central volume. The audio module includes a receiver capsule, a carrier unit coupled with the receiver capsule, and a counterweight coupled with the carrier unit. The microphone includes a suspension element that is coupled with the housing and carrier unit to suspend the audio module within the central volume. The suspension element includes an inner body that contacts the carrier unit. The suspension element includes first and second flanges extending outward from the inner body. The first and second flange are fixedly coupled with the housing. A cross-section of the first and second flange includes an arched region that extends at least partially to an inner wall of the housing. The arched regions are oriented in opposite directions.
