A shielded microphone, and method for shielding a microphone, are provided for
use in a communications device having a circuit board and a microphone,
especially where the device also has an antenna in close proximity to the
microphone. The microphone is provided in an electromagnetic shield (e.g.
formed as a shielding can) and a resilient separator (e.g. o-ring or disk) 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 microphone is thereby enclosed between the circuit
board and the shield, such that the shield shields the microphone against
electromagnetic energy radiated by the proximate antenna. The resilience of
the
separator accommodates the variation in the stacking of the components.
L'invention porte sur un micro blindé et sur le procédé de blindage connexe. Ce micro est destiné à servir dans un dispositif de communication mobile équipé d'une carte de circuits imprimés et d'un micro, notamment lorsque ledit dispositif est aussi muni d'une antenne montée tout près du micro. Le micro est logé dans un réceptacle offrant une protection électromagnétique (p. ex. une boîte de blindage) et muni d'un séparateur résilient (joint torique ou disque) monté sur le blindage. Le boîtier du dispositif est monté par dessus le séparateur et le blindage, alors que ce dernier est placé au dessus de la carte de circuits imprimés, le micro étant pris en sandwich entre le boîtier et la carte. En empilant ainsi les composants, le séparateur appuie sur le blindage de façon à pousser celui-ci contre la carte de circuits pour la mettre à la masse, le micro étant aussi branché à la carte de circuits. Ce dernier se trouve donc coincé entre la carte de circuits et le blindage qui l'isole de l'énergie électromagnétique diffusée par l'antenne avoisinante. La résilience du séparateur laisse un jeu suffisant pour l'empilage des composants.
