Abstract
A microphone assembly includes a housing having an interior with a front volume and a back volume. The housing has an acoustic input port coupling the front volume to an exterior of the housing. An acoustic sensor is disposed at least partially within the interior of the housing. At least a portion of the acoustic sensor is disposed at an interface between the front volume and the back volume. The acoustic sensor has an electrical signal output. A circuit board is disposed at least partially within the back volume of the housing and has a conductive member and an electrical contact. The circuit board also has a first portion carrying a first portion of the conductive member, and a second portion of the conductive member extending from the first portion of the circuit board toward the acoustic sensor. The second portion of the conductive member is electrically connected to the electrical signal output of the acoustic sensor.
