Abstract
A vehicle interior rearview mirror assembly (10) comprises an accessory (24), a reflective element (18) and a bezel (20). The mirror assembly may define portions of a pocket (23) that at least partially receives and secures the accessory therebetween when the reflective element is at least partially received in the bezel. The mirror assembly (110) may include a microphone (124) and an acoustic cover (126) positioned at least partially over one or more inlet ports (124j, 124k) of the microphone. The acoustic cover may include an outer air flow limiting layer (130b) that substantially limits air flow therethrough and a diffusing material (130a) that may space and support the outer layer from the inlet ports to substantially diffuse air flow that penetrates the outer layer. An acoustic barrier (132) may be positioned between a pair of inlet ports of the microphone to enhance the directivity of the microphone.

25. An interior rearview mirror system of a vehicle comprising:
-
an interior rearview mirror assembly comprising a reflective element and a casing, said interior rearview mirror assembly being adapted for attachment to an interior portion of the vehicle;
at least one microphone positioned in, at or adjacent to said interior rearview mirror assembly and having first and second inlet ports for receiving audible signals from within the vehicle cabin;
an acoustic cover positioned over said first and second inlet ports of said at least one microphone, said acoustic cover comprising an outer air flow limiting layer and at least one inner air flow limiting layer, said at least one inner air flow limiting layer being disposed at least partially over said first and second inlet ports and said outer air flow limiting layer being disposed at least partially over and spaced from said at least one inner air flow limiting layer and defining a space therebetween, said outer air flow limiting layer and said at least one inner air flow limiting layer being configured to substantially limit air flow therethrough; and
an acoustic barrier positioned across said microphone and between said first and second inlet ports, said acoustic barrier being configured to substantially acoustically isolate said first inlet port from said second inlet port. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

54. An interior rearview mirror system of a vehicle comprising:
-
an interior rearview mirror assembly comprising a reflective element and a casing, said interior rearview mirror assembly being adapted for attachment to an interior portion of the vehicle;
a microphone system positioned at, near or partially within said interior rearview mirror assembly and comprising;
a directional microphone having separated inlet ports for receiving audible signals from within the vehicle cabin;
a diffuser positioned at least partially over said inlet ports of said directional microphone, said diffuser being configured to substantially diffuse air flow around said inlet ports; and
an acoustic barrier positioned between said inlet ports and configured to substantially acoustically isolate one of said inlet ports from the other of said inlet ports, said diffuser being positioned at both sides of said acoustic barrier and over the respective inlet ports to diffuse air flow at both sides of said acoustic barrier, said acoustic barrier being adapted to delay reception of a sound signal by one of said inlet ports relative to the other of said inlet ports, said sound signal traveling through said diffuser. - View Dependent Claims (55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66)
