為了做好論文設(shè)計(jì),我先充分理解了電路的任務(wù)目的,建立了一個(gè)大致的電路工作工程概念,然后進(jìn)行細(xì)節(jié)的分析,理論的驗(yàn)證,最終得出一套最優(yōu)的方案。注意電源線不可搭在烙鐵頭上,以防燙壞絕緣層而發(fā)生事故。執(zhí)行 Tools/Auto Placement/Auto Placer,進(jìn)行自動(dòng)元件布局。若沒(méi)有所需要的元件,則需要建立一個(gè)新的原理元件庫(kù) ()。揚(yáng)聲器在電子元器件是一個(gè)最薄弱的器件,而對(duì)于音響效果而言, 它又是個(gè)最重要的器件 揚(yáng)聲器的分類 按能量方式分類:電動(dòng)(動(dòng)圈)揚(yáng)聲器、電磁揚(yáng)聲器、靜電(電容)揚(yáng)聲器、壓電晶體)揚(yáng)聲器、放電(離子)揚(yáng)聲器。外加使 P 區(qū)相對(duì) N 區(qū)為正的電壓時(shí),位壘降低,位壘兩側(cè)附近產(chǎn)生儲(chǔ)存載流子,能通過(guò)大電流,具有低的 電壓降 (典型值為 ) ,稱為正向?qū)顟B(tài)。 光耦的 結(jié)構(gòu)與種類 光電偶合器件(簡(jiǎn)稱光耦)是把發(fā)光器件(如發(fā)光二極體)和光敏器件(如光敏三極管)組裝在一起,通過(guò)光線實(shí)現(xiàn)耦合構(gòu)成電 —光和光 —電的轉(zhuǎn)換器件。光耦合器的主要優(yōu)點(diǎn)是:信號(hào)單向傳輸,輸入端與輸出端完全實(shí)現(xiàn)了電氣隔離隔離,輸出信號(hào)對(duì)輸入端無(wú)影響,抗干擾能力強(qiáng),工作穩(wěn)定,無(wú)觸點(diǎn),使用壽命長(zhǎng),傳 輸效率高 。 當(dāng) 1a 和 2a 隨發(fā)射極電流增加而使得 12( ) 1aa??時(shí),由式 () 中的分母121 ( ) 0aa? ? ? ,因此提高 了晶閘管的陽(yáng)極電流 Ia 。因此 ,特別是在大功率 UPS 供電系統(tǒng)中,晶閘管在整流電路、靜態(tài)旁路開(kāi)關(guān)、無(wú)觸點(diǎn)輸出開(kāi)關(guān)等電路中得到廣泛的應(yīng)用。具體這種功能的電路稱為雙穩(wěn)態(tài)觸 發(fā)電路。 關(guān)鍵詞 : 聲控 電路, 音樂(lè)彩燈,控制器 Sonic music lights controller design and production Author: Adilai Tutor: Tang hailing Abstract When you enjoy music, if can with music melody, flashing lights synchronization, not only can add joy change the atmosphere, it is a kind of beautiful enjoyment. Circuit is simple, low cost, especially suitable for home or work together with, the unit festival holiday lively atmosphere increase. The design principle of using sonic circuits, sonic circuits refers to strike applause, whistles, percussive sound and sound to stop such objects noise control circuit opening or closing the circuit. This design gives music lights controller scheme sonic design, but also the position and function of ponents for a more detailed analysis, use of protel software, mapped the circuit diagram, and finished PCB design. Eventually the welding and debugging by circuit after produced real.
