    摘要: A tamper detection apparatus includes a housing defining an internal cavity. A sensing device embodied as a microphone is positioned within the internal cavity of the housing, which may also be a protective grommet. A conductive element spans the internal cavity and is positioned in front of the microphone. The conductive element initiates a fault signal when a specified electrical condition is met to indicate a tampering or an attempted tampering with the microphone. The specified electrical condition may include an open circuit or a short circuit. The conductive element is in the form of a membrane or wire mesh.
