Abstract

A mirror-based audio system for a vehicle preferably includes an electrochromic interior rearview mirror system including an electrochromic interior rearview mirror assembly. The electrochromic interior rearview mirror assembly includes electronic circuitry for at least adjusting the reflectivity of an electrochromic reflector element. The electrochromic interior rearview mirror system further includes a plurality of microphones for receiving audio signals from within a cabin of the vehicle. The plurality of microphones generate output signals indicative of sound generated within the vehicle cabin. The microphones are positioned at the electrochromic interior rearview mirror assembly, adjacent to the electrochromic interior rearview mirror assembly, in an attachment to the electrochromic interior rearview mirror assembly, and/or within a module mounted to the windshield.
