1、 摘 要随着电磁式交互电子白板运用的设计制造日渐成熟,其运用也日渐广泛。 在电子白板的用户中,近 90%来自教育行业,近 10%来自商业用户,其它为 军事、政府等机构,由此可看出电子白板在教育领域受到了广大师生的亲睐。 但电子白板属于精密的电子仪器,对于其内部结构的紧密性和稳定性又很高的 要求,所以设计一台电子白板振动装置是很具有重要的理论意义和实用价值的。本设计通过对振动装置的调查和研究,对装置的原理和结构进行了探讨和 分析,提出了装置运动系统的设计思路。其次,讨论和确定了装置的总体结构 布局。本装置的运动系统分为主运动系统和振动系统,主运动系统采用卷扬机 控制吊机起吊以吊起载物台达到多角度
2、振动的目的,振动系统选择了电磁式激 振器,内部电磁线圈通入交流电后,铁心与衔铁发生相对振动而达到起振的目 的。再次,对装置电路结构和组件部件的选用进行了详细的计算和选取。 本设计所述的电子白板振动装置,有着安装方便、结构简单、制造成本低 等优点,主要运用与中型电子白板的检验。关键词:电子白板;电磁振动;运动系统。IAbstractWith the electromagnetic interactive whiteboard application in design and manufacture of increasingly mature, its use has become wides
3、pread. The electronic whiteboard users nearly 90% from the education industry nearly 10% from business users, the other for military, government and other institutions, which can be seen in the field of education electronic whiteboard by teachers and students of the pro-lai. But the electronic white
