基於單片機的音樂盒設計

⑴ 單片機音樂盒自己放歌

可以。單片機音樂盒依據單片機技術原理，通過硬體電路製作以及軟體編譯，設計製作出一個多功能多功能音樂盒，按照生產設定，可以進行自動放歌。單片機又稱微控制器，是一種面向控制領域嵌入式應用的集成化計算機晶元，主要用於工業控制、數據處理、信號處理、智能儀器、通信產品及民用消費產品等自動控制產品。

⑵ 急急急!!! 求AT89C51單片機實訓製作音樂盒程序編寫！以下為電路原理圖。謝謝...晶振是12M

⑶ 單片機怎麼做音樂盒啊

我也在做只是還沒做好下面的程序可以實現放1234567的音 如果換成譜子的話也是可以播放的，只是比較煩 還沒做譜子

⑷ 求一份C51單片機數字音樂盒（LCD1602顯示歌詞，歌詞需與音樂同步）的課程設計。程序為C語言程序的。

蜂鳴器不能唱歌，只會有調子，不知道顯示歌詞有什麼用，

此外，你給的分太少了，我只給你蜂鳴器唱歌的程序，

一個是單純的如何讓蜂鳴器播放音樂，

一個是紅外遙控播放音樂，音樂部分就只在MUSIC.C裡面，你看一下就行了，

樂音是由物體振動發出的，如果你的蜂鳴器的發聲頻率大約等於樂音的頻率，那麼就能發出類似的調子，具體的音符頻率表在我給的PDF的第30頁。

再奉送你一個專門單片機編歌譜曲的軟體。
