基于单片机的数字式音乐盒设计
基于单片机的数字式音乐盒设计数字式音乐盒是一种音乐播放器，它通过数字技术存储和播放音乐。
基于单片机的数字式音乐盒可以使用单片机控制音乐的播放，实现音符和旋律的发声和控制。
本文将介绍如何设计一款基于单片机的数字式音乐盒。
一、音乐盒基本原理音乐盒是通过一个带有齿轮的转子，以弹簧的力量驱动，使得钢片受到磁力响应并发声，从而发出旋律。
数字式音乐盒是通过数字技术将音乐编码为数字信号，并存储在芯片中，通过解码器将数字信号还原为音符和旋律发声。
二、单片机控制电路设计1.芯片选择要设计一个数字式音乐盒，需要先选择一款合适的单片机，常用的有AT89C51、STC89C52等。
这里选择一款性能好且价格适中的STC89C52单片机。
2.存储器选型数字式音乐盒的数字信号需要存储在内存中，为了方便起见，使用一个4Mbit的Flash记忆芯片作为存储器。
3.音频输出电路数字信号需要通过解码器进行还原后才能通过音频输出电路输出。
可以使用一对耳机或者喇叭，同时需要用到音量电位器控制音量。
三、软件程序设计1.数字信号编解码算法的设计，可以使用目前较为流行的MIDI编码格式。
2.音乐信号输入模块设计，可以使用USB接口或SD卡接口。
3.数据接收模块设计，可以使用串行通信或者并行通信。
4.数字信号存储模块设计，使用Flash记忆芯片。
5.控制模块设计，实现单片机控制音乐盒的所有操作。
四、实现效果基于单片机的数字式音乐盒实现较为简单，但是需要注意以下几点：1.考虑使用定时器计算控制音乐的播放时间，保证旋律按照要求执行。
2.使用ADC(模拟-数字转换器)读取音量电位器值，对音量进行控制。
3.在使用USB接口时，需要有电路板，使得USB通信接口稳定，可靠。
基于单片机的数字式音乐盒是一种方便实用的音乐盒，通过数字技术的运用，实现了音乐的存储和播放，可广泛应用于各个领域中。

【关键字】音乐盒；STC 12c5608ad单片机； KEIL； PROTEUS；课程设计目的应用单片机，利用它的原理组成一个音乐随身听。
本课程设计是主干实践课。
课程大幅提高的任务在于提高学生综合运用所学知识理论、分析解决问题的能力。
课程设计任务∙以单片机为核心部件组成一个音乐；∙利用单片机的定时器产生乐谱的各种频率方波，由蜂鸣器发出声音设计原理音调的确定：不同音高的乐音是用C 、D 、E 、F 、G 、A 、B 来表示，这7个字母就是音乐的音名，它们一般依次唱成DO 、RE 、MI 、FA 、SO 、LA 、SI, 即唱成简谱的1、2、3、4、5、6、7，相当于汉字“多来米发梭拉西”的读音，这是唱曲时乐音的发音，所以叫“音调”，即Tone 。
把C 、D 、E 、F 、G 、A 、B 这一组音的距离分成12个等份，每一个等份叫一个“半音”。
两个音之间的距离有两个“半音”，就叫“全音”。
在钢琴等键盘乐器上，C –D 、D –E 、F –G 、G –A 、A –B 两音之间隔着一个黑键，他们之间的距离就是全音；E –F 、B –C 两音之间没有黑键相隔，它们之间的距离就是八度。

其类型从音乐卡片到CD、MP3 等多种多样，制作原理也各不相同。
声音是通过振动产生的。
单片机对某一I/O 引脚以一定的频率循环置1和清0，这一引脚便产生一定频率的方波，该方波通过放大后作用于扬声器便产生一定频率的声音。
若改变输出方波的频率，产生的声音也就改变了。
通过控制输出方波的时间长短,声音的长短也就得到控制。
因此，根据乐谱，单片机就可产生电子音乐。
音乐中最关键的两个要素是音符和节拍。
单片机控制的音乐发生器系统由硬件电路和软件两部分构成。
利用单片机控制的电子音乐发生器软硬件上具有独特的优点，系统的开发周期短，成本低，电路制作容易。
更换歌曲时，硬件电路无需作任何修改，只需修改软件即可实现。
软件编程时，可用51系列单片机的汇编语言。
同时还可根据个人的习好通过软件改变节拍的延时时间，增加电子音乐的趣味性。
1.2 设计思路采用汇编语言程序设计的方法结合硬件电路设计方法，利用Lab6000实验箱上已有芯片来实现音乐盒的各项功能。
1)提出方案利用定时器计时这个半周期时间，每当计时到后就将输出脉冲的I/O反相，然后重复计时此半周期时间再对I/O口反相就可在I/O脚上得到此频率的脉冲。
当键盘有键按下时，判断键值，启动计数器T0，产生一定频率的脉冲，驱动蜂鸣器，放出乐曲。

我通过仿真发现，按下按8 总结通过对单片机的学习，发现对单片机的硬件设计，软件设计掌握的a您好，为你提供优秀的毕业论文参考资料，请您删除以下内容，O(∩_∩)O谢谢！！！A national survey was recently launched to evaluate the eye health of Chinese children andteenagers.On June 6, China 's annual National Day for Eye Care, the China Youth Development ServiceCenter and Zhejiang Medicine, a leading li sted Chinese pharmaceutical company, jointlyannounced the kickoff of the survey.In about one month, a questionnair e compiled by top eye care medical experts in China willbe distributed through multiple online partners, including He , as well asthrough offline survey events held in universities, middle schools and primary schools acrosst he country.A report will be released based on the survey statistics and analysis, and most importantly,guidelines for pa rents and youth on how to care for the eyes and prevent myopia — agrowing problem in China's digitized society, will also be attached on the report."Myopia is not only a disease that makes people see things blurrily, but also leads to sev erecomplications, such as glaucoma (increased pressure within the eyeball), and can causeblindness," said Zhou Yueh ua, an established eye care specialist with Beijing TongrenHospital."It is very important for parents and children to k now about the risk and care for their eyes."There are about 450 million myopia patients in China. Among Chinese my opia patients,30million are severe patients, according to ZhouThe prevalence of myopia among high school and colleg e students is more than 70 percent,and the situation is continuously worsening, he added.Sun Zhu, director with the C hina Youth Development Service Center, said long hours ofstudy, lack of exercise, especially outdoor activities, and att achment to electronic screen aresome of the top reasons behind the widespread myopia problems, and the increase ofy ounger patients, although China has made great progress in improving the hardwarefacilities and lighting conditions i n schools.He said he hopes the survey will alert people on the threatening situation, and also helpmedical experts to be tter guideline parents and children's behaviors to care for eyes, basedon the timely and factual statistics the survey col lected.A series of follow-up events will also be held in six cities, including Jinan in Shandongprovince, and Changsha i n Hunan province, to educate people on how to care for eyes afterthe survey started. More and more Chinese are jogging to get and stay fit. Most joggers will run alone, but some will jog with friends or even coaches. The Beijing Olympic Forest Park is one of the most popular spots. It is packed with runners in the afternoon, usually after work, and at weekends. Jogging after a whole day's work can be a way to unwind. It is true for He Wenjun, whose workplace is right near the forest park. She discovered her athletic aptitude at the age of seven, when she began playing tennis. Then she turned to jogging, and she has persevered with it for 10 years. "I come to jog almost every day after work, whenever I have time. I think jogging is good for my health. And for me, a girl, it helps me to achieve to eternal goal, to keep slim," He said. He says she prefers jogging alone, so she can focus better. She loves jogging, even during Beijing's smoggy days. "If the smog is severe, I'll hold off jogging for a while. But if I really want to get away from work, I'll wear a mask, or just ignore the smog and go on jogging," she said. For those who are not so athletic, jogging also has its attractions. Wu Houbin started roughly two years ago, when he was severely obese. Within two months, his weight dropped from 82 kilograms to 64 kilograms. The success helped him recover health, and he has made friends. "Jogging does not require speed, but stamina. If you want to stick to the game, you need to take it as a mission, a habit, and then eventually a hobby," Wu said. But persevering with jogging is not always easy. Jogging is beneficial for heart-lung function, and the skeletal system, but doctors say improper technique damages the joints, especially the knees and ankles. "Excessive jogging wears down the body, and harms one's health. Poor technique harms the muscles and skeleton, and can cause secondary injures. And, jogging in a bad environment can cause circulation problems," said Lu Zhiyong, attending doctor, Sports Hospital, General Admin. of Sports.Dr. Lu has some tips for joggers, and thosewho are thinking of taking it up.He says peoplesh ould first evaluate their physical condition, to decide the amount and type of exercise, and jogging in the open air is better running on a treadmill. Conrad Macaowill run special programs for the entire month of October this year to support the Hong Kong Cancer Fund's Pink Revolution, an annual campaign that seeks to raise awareness and funds for breast cancer research, the hotel recently announced. A major sponsor of the campaign for three years in a row, Conrad Macao has pledged to donate a portion of its proceeds to the fund,includ ing those collected from selling its popular bear and rubber duck merchandise, in limited pink editions. Pink is the theme for floral arrangements and decorations in the hotel in October. In addition, on Fridays that month, members of the management and staff will add something pink to their uniforms, regular e-mails and handwritten guest cards. "Breast cancer is the most prevalent type of cancer among women in Hong Kong and is also of significant concern in Macao and around the world, regardless of age," general manager Bede Barry said in a statement. The hotel has enlisted the support of a number of international and local celebrities to help drive the cause, including South Korean actor Jung Suk Won. This year, a lucky guest who stays at the hotel during the campaign and also donates money for the cause will win a necklace specially designed by Arte Madrid, a Spanish jewelry brand. Women should strive to balance quality of work and life, and have children at a young age. As a doctor I see much suffering because of this imbalance. Xiao Ying, 36, works for a large law firm. Her job means lots of travel, a heavy caseload and a large number of meetings, so her schedule is hectic. She has been pregnant twice, but had abortions on both occasions because she felt her busy,high-pressure career wasn't conducive to raising a child. She planned to have children once she had achieved career success so she could provide a stable environment for her baby. After 10 years, Xiao felt the time was right, and she tried to conceive for about six months, but was unable to become pregnant. I conducted comprehensive physicalcheckups. The results suggested that Xiao's ovarian function has declined and a bilateral oviduct blockage has occurred, meaning that in vitro fertilization is her only option. So, after reducing her workload, Xiao underwent IVF treatment. Luckily, she got pregnant after just one treatment cycle, but later experienced vaginal bleeding, and rushed to the hospital. I told her to rest and carry on with the treatment (to prevent a miscarriage). As Zubin Zarthoshtimanesh, a yoga guru, demonstrated postures at a high school stadium in Dujiangyan city, Sichuan province, some 200 students sat on colorful mats watching him closely. It was part of the first India-China international yoga festival in the provincial capital, Chengdu, in Southwest China, where more than 1,000 fans from home and abroad gathered for lessons from 20 leading practitioners of the ancient Indian regimen, from June 17-21. Yoga is to India what perhaps tai chi is to China. Many countries other than India and China, also held the first World Yoga Day on June 21, after the United Nations last year agreed to Indian Prime Minister Narendra Modi's suggestion that a special day be marked in the year for the global practice of the stress-busting regimen, which is already a multibillion dollar industry in the United States. Modi said in the speech: "Yoga is an invaluable gift of India's ancient tradition. ... It is not about exercise but to discover the sense of oneness with yourself, the world and nature."Zarthoshtimanesh, who runs his own yoga center, Iyengar Yogabhyasa, in the Indian financial capital of Mumbai, says: "Chinese students are very respectful. For me, all students are the same no matter what their race is and where they come from. The most important thing is to remove mental walls." Zarthoshtimanesh learned yoga from the late Yogacharya Iyengar and traveled with the master to different countries. Consulate General of India in southern China's Guangzhou city organized the Chengdu festival. A terrifying wooden bridge in China has just been replaced by a glass one. This, the world’s longest glass-bottomed walkway, is located in Shiniuzhai Geopark in Hunan, and spans 300m (984f) and is 180m (590f) above ground. The floor is made of double-layered glass that is24mm (0.94in), and is reportedly 25 times stronger than regular window glass. The bridge had previously been made of wood, linking the two peaks of Stone Buddha Mountain, but 11 engineers working 12 hours a day converted it to glass. Previously, you were considered brave if you steeled yourself to cross the wooden walkway; now, with its glass bo ttom, the bridge is already being referred to as “hero bridge.”The popular chain's longtime executive chef embraces mapo tofu and other exotic elements for the burger-driven menu, Liu Zhihua reports.At the age of 37, Shanghai native Lin Zhengu has become a star as a Western cuisine chef in the Chinese metropolis, a city that has a wealth of Western restaurants. The executive chef of Blue Frog Bar and Grill, a popular burger-based restaurant and bar chain on the Chinese mainland, Lin is the soul of the restaurant franchise's team of more than 550 chefs. Many of the franchise's most popular dishes are his brainchild. Lin says his secret of success is innovation rooted in experience: He spends months every year traveling and eating worldwide, seeking new ingredients and inspirations that could improve the offerings of Blue Frog restaurants. The restaurant chain regularly launches a new seasonal menu, usually featuring eight new dishes with fresh ingredients. The best-selling seasonal dishes later replace the least popular items on the regular menu, which is usually updated in late fall and boasts a selection of about 40 dishes. "Food should have no boundaries," Lin says. "As long as the food tastes good and is healthy, it doesn't really matter where it originates or how it is cooked." Lin likes to give the American-style restaurants' menu some culinary touches from other countries, such as China and Mexico, and customers love such innovation, he says. He started his career as an apprentice in a Chinese kitchen in 1993. By chance he learned from a French chef in 1994, and soon became enamored with the world of Western food. During the next couple of years, he received strict training in Western culinary art from French, Chinese and German chefs. That was rare for a Chinese chef in the 1990s, he says－and so was being a Chinese chef who spoke fluent English. When an American entrepreneur invited him to join in his startup Blue Frog in 2000, Lin didn't hesitate to resign from a five-star hotel to work in the new restaurant with just five chefs, eager to explore the excitement of a life that had yet to unfold. Since that Shanghai launch, Blue Frog has opened 24 branches in seven cities across China, including Beijing, Tianjin, Chongqing and Nanjing in Jiangsu province. The new menu for this fall, which was launched in early September, showcases how flavors of East and West meet to create a variety of delicious burgers and other entrees in the cozy, soft-lit restaurants. I liked the mapo burger best. Just imagine the flavorful combination of the hot, mildly numb-spicy mapo tofu sauce and grilled 100-percent Australian beef patty, along with a slice of cheddar cheese and a side of french fries. The savory sauce helped highlight the patty's juicy, tender texture and its delicious beef flavor. Matching that Sichuan flavor with cheese created a new taste experience.。
