安徽師范大學(xué)皖江學(xué)院畢業(yè)論文（設(shè)計(jì)）開題報(bào)告書 題 目 基于 AT89C51 單片機(jī)的音樂(lè)盒設(shè)計(jì) 選題的意義及研究狀況： 隨著人類社會(huì)的發(fā)展，人們對(duì)視覺(jué)聽覺(jué)方面的享受提出了越來(lái)越高的要求，小小 音樂(lè)盒可以給人們帶來(lái)美好的回憶，提高人們的精神文化享受。傳統(tǒng)的音樂(lè)盒是機(jī)械的，體積笨重的，發(fā)音單調(diào)，不能實(shí)現(xiàn)批量生產(chǎn)。本文設(shè)計(jì)的音樂(lè)盒是以單片機(jī)為核心元件的電子式音樂(lè)盒，體積小，重量輕，能演奏和旋音樂(lè)，功能多，使用方便，可以批量生產(chǎn)，具有一定商業(yè)價(jià)值。 為了更好地熟悉和掌握單片機(jī)的基本功能和編程，我們以 AT89C51 為基礎(chǔ)設(shè)計(jì) 電子音樂(lè)盒 。 AT89C51 單片機(jī)電子音樂(lè)盒集成多個(gè)硬件資源模塊，每個(gè)模塊各自可以成為獨(dú)立的單元，也可以相互組合， 因此，可以為不同階層的單片機(jī)愛(ài)好者所用。 主要內(nèi)容、研究方法和思路： 本設(shè)計(jì)采用了揚(yáng)聲器發(fā)聲來(lái)實(shí)現(xiàn)歌曲的播放，能保持基本音調(diào)不變，流暢播放出歌曲。 I/O 口產(chǎn)生一定頻率的方波，驅(qū)動(dòng)蜂鳴器，發(fā)出不同的音調(diào)，從而演奏樂(lè)曲（最少三首樂(lè)曲，每首不少于 30 秒） LCD 顯示信 ，播放時(shí)顯示歌曲序號(hào)（或名稱） ，暫停，播放。 ：顯示樂(lè)曲播放時(shí)間或剩余時(shí)間 1． 準(zhǔn)備情況 （查閱過(guò)的文獻(xiàn)資料及調(diào)研情況，現(xiàn)有儀器、設(shè)備情況、已發(fā) 表或撰寫的相關(guān)文章等）： [1] 閻石 . 數(shù)字電子技術(shù)基礎(chǔ) . 北京 :
