An MP3 audio play system is designed and created under a radio frequency (RF) signal coverage environment for exhibition narration. The proposed system contains wall sets to be installed to pronounce address code by RF interrogation, and user sets to be hand-carried to activate the audio contents on MP3 by RF receiver. Both wall set and user set are controlled using microprocessors. The proposed system is termed as e-narrator system for application in different exhibition environments. Based on the proposed system configuration, program content can easily be edited, selected and download to MP3. The wall set pronounces each exhibition works on sequential number as address code; while the user set receives this address code and can correctly search for audio narration record on MP3 memory very quickly. Control program is designed to play MP3 from any previous location, instead of the beginning, by a block shift control. The e-narrator system is a very simple organization system with easy installation for implementations. Many humanization functions can also be built into the proposed system and tested with different scenarios.
