GPS Triggered, Radio Frequency Controlled Audio System

Abstract

An audio information system comprising an audio player that is triggered by an RF signal. The RF signal is generated by a GPS controller that recognizes a location and sends a command to the players to play a specific track. The system consists of individual audio players and central GPS/RF transmitters. Each individual player contains all of the audio content, and the appropriate track is selected by an RF command. The GPS/RF controller contains a list of locations, and when the GPS controller is near one of the locations an RF signal is transmitted indicating which track for the audio players to play.
