摘要
随着科技的飞速发展,人们的生活节奏越来越快,多数人长期处于压力过大的状态。音乐对于调节人的心理压力来说是一种很有效的方式,因此,各式各样的音乐盒开始普及。由于容量大、操作方便、价格便宜等优点,数字音乐盒逐渐成为人们的首选。这里以电子技术为基础,设计了一款数字音乐盒。它以单片机为核心,主要由外围控制电路、外接电路、发声电路、电源电路等组成整个系统。音乐的播放可用按键或者红外遥控器实现,同时还可以播放外接设备中的音乐。该系统电路结构简单、功能强大、具有很强的实用性;软件设计简便易懂,适用范围广,具有广泛的可移植性,对于不同音乐只需改变相应的程序即可。此外,系统还扩展了部分功能,设计了外接播放设备的接口,人们可以随意切换自己喜欢的音乐。
With the rapid development of science and technology,the life pace for us has become faster and faster. Most people are usually under the high pressure for a long time. Thus,music is the most effective pathway to release our psychological pressure,and several kinds of music boxes has been widely used in our daily life. Because of the advantages of large capacity,convenient operation and low price,the digital music box has been become the first priority for us. Therefore,based on the electronic technology a digital music box is designed here. It takes the monolithic integrated circuit as the core circuit,and is mainly constituted by the peripheral control circuit,the external circuit,the sound production circuit,the power supply circuit and so on. Music can be played by the buttons or the infrared remote control,and also can be played in external devices. In short,this digital music box is characterized with the simple circuit structure,powerful function and strong practicability,and its software design is simple and easy to understand,wide range of application and wide portability. And it can be used for different music by changing the corresponding program. In addition,some expanded functions have been also achieved including that an interface has been designed for the external playback device,and people could switch their favorite music at any moment.
