【導(dǎo)讀】為了實(shí)現(xiàn)單片機(jī)控制音樂播放，此次畢業(yè)設(shè)計(jì)做出了嘗試，即電子音樂盒的設(shè)計(jì)?，F(xiàn)選用AT89S51單片機(jī)。主要設(shè)計(jì)模塊包括數(shù)碼管顯示部分，功能鍵盤部分，蜂鳴器發(fā)聲部分，彩燈部分。采用按鍵開關(guān)，通過單片機(jī)P3口控制，實(shí)現(xiàn)歌曲播放順序的調(diào)換和暫停播放功能；現(xiàn)單色長亮和閃爍效果。子電工等方面知識,用KeilC51編程軟件編程，用PROTEUS單片機(jī)仿真軟件仿真。出不同的音調(diào)，從而演奏樂曲。音樂盒的起源，可追溯至中世紀(jì)歐洲文藝復(fù)興時期。當(dāng)時為使教會的的鐘塔報時。，而將大小的鐘表上機(jī)械裝置，被稱為“可發(fā)出聲音的組鐘”。300多年來席卷全球市場的機(jī)械音樂盒的最大魅力，也許就在于它能。成為人們表達(dá)美好情感，追思逝去歲月的最佳。機(jī)械音樂盒的發(fā)展史，可追溯至14世紀(jì)初期，所發(fā)明掛在教堂鐘樓上的排鐘,1811年以來，瑞士曾經(jīng)是這項(xiàng)技藝的中心，它和瑞士鐘表工業(yè)一樣，兩者相輔相成，一段時間名領(lǐng)風(fēng)騷，稱霸全球。音樂盒300多年的產(chǎn)品發(fā)展，同時也是人類文明300多年發(fā)展的歷史鑒證。
