毕业设计(论文) 题目: 音频功率放大器专业: XXXXXXXXXXX 班级: XXXXXXXXX 学号: XX 姓名: XXXXX 指导老师: XXXX XXXXXXXXXXXXXX 二〇一四年六月 I 摘要音频功率放大器,简称功放。随着经济的发展和社会进步,人们对功放的使用的越来越多,对功放的品质要求也逐渐变高。要有高品质的音质就需要好的元器件,好的电路。音频功放( APA ) 技术的最新发展进一步提高了音响的音质以及人们生活水平的不断提高,各种新型家庭影院的新技术、新品种器材不断涌现, 市场中的音响设备品种繁多,音响爱好者被商店里的设备搞得眼花缭乱本设计采用的是曾被誉为功放之王的 NE5532 芯片做前级放大和音调电路。后级部分采用 TDA2030 做功率放大, 可以很方便的将声道进行功率放大。配合 10W 的全音喇叭,能很好的将音频信号进行较小失真的放大。关键词:功放; NE5532 ; TDA2030 ; 10W II Abstract Audio power amplifier, referred toasthe power amplifier. With the economic development and social progress, more and more people use the power amplifier, the required quality ofpower amplifier has e high. Tohave high quality sound requires ponents, good circuit. Audio power amplifier (APA) the latest development oftechnology tofurther improve the sound quality and the improvement ofpeople's living standard, various kinds ofnew home theater ofthe new technology, new varieties are emerging market equipment, sound equipment ofvariety, audio enthusiasts bythe store equipment tosee things inablur The design isadopted byNE5532 power amplifier chip known asthe king ofpreamplifier and tone circuit. After the class part adopts TDA2030 power amplifier, can bevery convenient tothe channel power amplifier. With the 10W Tritone horn, can bevery good tothe audio signal isless distortion amplifier.
