Claim Text:
1. A microphone system comprising: a base; a lid coupled to the base to form a package having an interior chamber, the package having an inlet aperture; a member coupled with the base within the interior chamber, the member having a member aperture, the member including a circuit die with a circuit die aperture; and a microphone die connected to a substrate and having a diaphragm and coupled to the member within the interior chamber, the member being between the base and the microphone die, the member aperture and inlet aperture being laterally offset, the member aperture, member, and base forming an acoustic path between the inlet aperture and the microphone die, wherein acoustic signals enter the inlet aperture and travel laterally between the circuit die and the substrate and in direct, lateral and simultaneous contact with the circuit die and the substrate, through an acoustic channel, the acoustic channel formed laterally between the member aperture and the inlet aperture and positioned directly below the circuit die and further wherein, the acoustic signals travel from the acoustic channel through the circuit die aperture in a direction toward the diaphragm and contact the diaphragm.
