Microphone assembly for use with an aftermarket telematics unit
First Claim
1. A microphone assembly for use with an aftermarket telematics unit mounted in a passenger compartment of a vehicle, the aftermarket telematics unit having a chamber having an opening that generally faces towards a rear of the vehicle, the microphone assembly comprising:
- a directional wideband microphone disposed within the chamber, anda preamplifier mounted at least partially within the directional wideband microphone, the preamplifier having a pair of electrical leads for both electrically connecting and structurally attaching to the aftermarket telematics unit,wherein the directional wideband microphone and the preamplifier are mounted to the aftermarket telematics unit via the pair of electrical leads such that the pair of electrical leads are the sole points of attachment of the directional wideband microphone and the preamplifier with the aftermarket telematics unit, wherein each electrical lead of the pair of electrical leads are spaced apart from one another, and wherein the pair of electrical leads cooperate to stand off a rear surface of the directional wideband microphone and a rear surface of the preamplifier from a surface of the aftermarket telematics unit.

Abstract
A microphone assembly for use with an aftermarket telematics unit mounted in a passenger compartment of a vehicle is disclosed herein. The aftermarket telematics unit has a chamber having an opening that generally faces towards a rear of the vehicle and the microphone assembly includes, but is not limited to, a directional wideband microphone disposed within the chamber. A preamplifier is internally mounted within the directional wideband microphone. The preamplifier has an electrical lead and is both electrically and structurally attached to the aftermarket telematics unit via the electrical lead. The electrical lead is the sole means of physical attachment between the directional wideband microphone and the preamplifier, on the one hand, and the aftermarket telematics unit on the other hand.

20. A microphone assembly for use with an aftermarket telematics unit mounted in a passenger compartment of a vehicle, the aftermarket telematics unit having a Printed Circuit Board (PCB board) to control various functions of the aftermarket telematics unit, the aftermarket telematics unit further having a chamber having an opening that generally faces towards a rear of the vehicle, the microphone assembly comprising:
-
a directional wideband microphone disposed within the chamber and having an acoustic axis, the directional wideband microphone being oriented within the chamber such that the acoustic axis is directed through the opening and towards the rear of the vehicle; a preamplifier mounted at least partially within the directional wideband microphone, the preamplifier having a pair of electrical leads for both electrically connecting and structurally attaching to the PCB board, a grill member positioned to cover the opening, the grill member having a plurality of grill openings that are sized to render the grill member acoustically transparent; a foam body disposed within the chamber, the foam body being positioned between the directional wideband microphone and the opening and the foam body having a density that is effective to resist a transmission of sound energy of a predetermined frequency; and a boot positioned around the directional wideband microphone, the boot being acoustically transparent, the boot comprising an elastomeric material, and an outer surface of the boot being contoured to substantially conform to an internal portion of the chamber, wherein the directional wideband microphone and the preamplifier are mounted to the aftermarket telematics unit via the pair of electrical leads such that the pair of electrical leads are the sole points of attachment of the directional wideband microphone and the preamplifier with the aftermarket telematics unit, wherein each electrical lead of the pair of electrical leads are spaced apart from one another, wherein the pair of electrical leads cooperate to stand off a rear surface of the directional wideband microphone and a rear surface of the preamplifier from a surface of the aftermarket telematics unit and wherein the directional wideband microphone is disposed within the chamber such that a rear surface of the directional wideband microphone is spaced apart from any other surface by at least two millimeters.
