Abstract

Un sistema de audio comunicacion para un vehiculo incluye una fuente primaria de audio que produce una senal primaria de audio; una fuente secundaria de audio que produce una senal secundaria de audio; un altoparlante; un conmutador de ignicion de vehiculo, que tiene una posicion de encendido y una posicion de apagado, y un relevador. Las fuentes de audio primaria y secundaria pueden ser conectadas alternativamente, de manera transmisible, al altoparlante, por el relevador. El relevador recibe la senal primaria de audio y trasmite sustancialmente la senal primaria de audio al altoparlante cuando el conmutador de ignicion del vehiculo esta en la posicion de encendido y no esta presente la senal secundaria de audio. El relevador recibe las senales primaria y secundaria de audio y trasmite sustancialmente la senal secundaria de audio al altoparlante cuando el conmutador de ignicion del vehiculo esta en la posicion de encendido. El relevador recibe la senal secundaria de audio y trasmite sustancialmente la senal secundaria de audio al altoparlante durante un periodo de tiempo predeterminado despues que se ha conmutado el conmutador de ignicion del vehiculo de la posicion de encendido a la posicion de apagado. Se puede usar el sistema de audio comunicacion recibiendo una senal primaria de audio desde una fuente primaria de audio en un vehiculo; excitando un altoparlante con la senal primaria de audio; recibiendo una primera senal secundaria de audio desde una fuente secundaria de audio en el vehiculo; interrumpiendo la senal primaria de audio y excitando el altoparlante con la primera senal secundaria de audio; apagando la ignicion del vehiculo; iniciando un periodo de tiempo predeterminado; recibiendo una segunda senal secundaria de audio desde una fuente secundaria de audio, dentro del periodo de tiempo predeterminado; y excitando el altoparlante con la segunda senal secundaria de audio.
