1. A communication system for a vehicle passenger compartment comprising:
- a first microphone generating first microphone signals located at a first position within said passenger compartment;
a second microphone generating second microphone signals located at a second position within said passenger compartment, said second microphone separated from said first microphone by a first distance;
a digital signal processor receiving said first and second microphone signals;
a first speaker located proximate said first microphone, said first speaker connected to said digital signal processor to output said second microphone signals in response to said digital signal processor;
a second speaker located proximate said second microphone, said second speaker connected to said digital signal processor to output said first microphone signals in response to said digital signal processor; and
an audio entertainment system electrically coupled to said digital signal processor, said audio entertainment system outputting audio signals through said first and second speakers;
said digital signal processor substantially canceling communication of said first and second speaker output from said first and second microphone signals.

Abstract
An audio communication system for use in the passenger compartment of a vehicle providing full duplex communication through a plurality of speakers and microphones while substantially eliminating unwanted external interference and feedback. A digital signal processor further integrates an audio entertainment and mobile transceiver subsystems. The subsystems are operated by the microphone from one or more positions within the vehicle so that each passenger has access to a cellular phone or can control the audio entertainment system.
