紅外線無線音樂鍵盤

本論文是實現一個無鍵盤電子琴系統，主要是藉由多媒體影音平台並利用硬體描述語言HDL編寫音樂發聲電子電路與鍵盤觸控LCD顯示系統。鍵盤輸入的部份是利用多顆紅外線接收裝置，以光遮罩的方式，透過多媒體平台硬體輸入介面，以程式語言來模擬鍵盤的彈奏，同時傳輸至相對應的發聲與顯示系統，其結果我們創造出一個多媒體無線電子琴系統(Wireless Keyboard System)。

This paper is addressing a preliminary multimedia application of designation and implementation for a wireless music keyboard. The music platform has used the a multimedia simulation board which consists the Altera FPGA chips, audio decoder, acoustic speaker, VGA video display and other multimedia hardware on this board. The music keyboard has used infrared sensor which are connected into the simulation platform. We have written hardware description languages VHDL and Verilog codes which are to define and implement the required functions for this music keyboard platform. The result of this system is encouraged. This keyboard worked as a basic music keyboard which generated a music notes and the key-strode will be displayed on VGA monitor. The music platform works differently than the traditional music keyboard which the player must touch the keypads physically. This music system is used infrared sensors to detect whether these keypads were pressed or not. So there is no physically touched required for this system. The system is still in the primitive stage, but it can be further expanded for a professional purpose.
