Abstract
A shielded microphone, and method for shielding a microphone, are provided for use in a communications device having a circuit board and a microphone. The microphone is provided in an electromagnetic shield and a resilient separator is provided over the shield. The device housing is stacked over the separator and shield, while the latter are stacked over the circuit board so that the separator and shield, with microphone there under, are sandwiched between the housing and the circuit board. By this sandwiching the separator is loaded onto the shield to drive the shield directly against the circuit board to make an electrical ground connection therewith, the microphone also being electrically connected to the printed circuit board. The resilience of the separator accommodates the variation in the stacking of the components.
