摘   要
單放機(jī)——又名隨身聽，是一種集娛樂性和學(xué)習(xí)性為一體的小型電器，因?yàn)榭梢噪S身攜帶，方便價(jià)廉，曾經(jīng)一度流行。隨著大學(xué)英語四級的要求，隨身聽給廣大學(xué)子們帶來了很大的便利，不論在什么時(shí)候都可以想練習(xí)聽力就練習(xí)聽力，而且不會打擾別的學(xué)生，正因?yàn)檫@樣曾經(jīng)在各個(gè)大學(xué)幾乎普及，市場容量巨大。它是用蓄電池驅(qū)動電機(jī)來提供電力，將磁信號轉(zhuǎn)換成為聲音信號來工作的，為了滿足不同人群的需求隨身聽做出了很多造型，其中超薄的一款很受歡迎。
同時(shí)在三維流行的今天，各種三維軟件陸續(xù)成為熱點(diǎn)，CAD/CAM技術(shù)在產(chǎn)品研發(fā)當(dāng)中所占的比例越來越重。本文運(yùn)用了CATIA三維軟件實(shí)現(xiàn)AEY-304B型單放機(jī)進(jìn)行簡單的逆向設(shè)計(jì)，主要是結(jié)構(gòu)和外形的設(shè)計(jì)，運(yùn)用了CATIA的強(qiáng)大曲面功能來做外形，以及自頂向下的設(shè)計(jì)模式來設(shè)計(jì)機(jī)械結(jié)構(gòu)部分，配合仿真模塊的強(qiáng)大功能快速、簡潔的模擬出了其內(nèi)部機(jī)構(gòu)的工作原理。從而縮短設(shè)計(jì)周期，降低設(shè)計(jì)成本，使設(shè)計(jì)效率大大提高。

AEY-304B-type-player reverse design of CATIA
Abstract：Player also named suishenting, is a set of entertainment and learning as one of the small electrical appliances, Because it can carry easyly and cheap, once popular。And CET-4 has been more and more important,a lots of students used it because they can get more facilitates. and at any moment can be used when you want practice listening and will not disturb other students. Because of this the University has almost universal in all, a huge market capacity. It is battery-driven motor to provide power, the magnetic signal is converted into sound signals to work, in order to meet the needs of different groups of people made a lot of players shape, a very popular one was the thin.
At the same time the 3D is popular today, all gradually become a hot three-dimensional software, CAD / CAM technology has be more and more inportant,In this paper, the CATIA software AEY-304B D-type reverse-player simple design, primarily the design of the structure and shape, the use CATIA`s powerful capabilities to do surface shape, and top-down design patterns to design the mechanical structure of simulation module, simple to simulate its internal organization works. Thus shortening the design cycle, reduce design costs, design efficiency greatly improved.
