爱迪生主要成就:
一、留声机
1877年,爱迪生发现电话传话器里的膜板随着说话声会引起振动的现象,便拿短针作了试验,从中得到很大的启发。说话的快慢高低能使短针产生相应的不同颤动。那么,反过来,这种颤动也一定能发出原先的说话声音,于是他开始研究声音重发的问题。
8月15日,爱迪生让助手按图样制出一台由大圆筒、曲柄、受话机和膜板组成的“怪机器”,制成之后,卷在刻有螺旋槽纹的金属圆筒上,让针的一头轻擦着锡箔转动,另一头和受话机连接,然后爱迪生摇动曲柄,对着受话机唱歌,之后把针又放回原处,再摇动曲柄,接着机器就回放出爱迪生的声音。
二、电灯
与人们通常的认识恰恰相反,最初电灯的发明者不是爱迪生,爱迪生是改进了电灯。早在1801年,英国一位名叫汉弗里·戴维的化学家就在实验室中用铂丝通电发光;
1810年,他又发明了用两根通电碳棒之间发生的电弧而照明的“电烛”,这算是是电灯的最早雏形。另一位英国电技工程师约瑟夫·斯旺经过近30年的研究,于1878年12月制成了以碳丝通电发光的真空灯泡。
三、电影
1889年,爱迪生发明了一种活动电影摄影机,这种摄影机用一个尖形齿轮来带动19毫米宽的没打孔的胶带,在棘轮的控制下,带动胶带间歇移动,同时打孔。这种摄影机由电机驱动,遮光器轴与一台留声机连动,摄影机运转时留声机便将声音记录下来,并且可以连续拍摄图像。
1891年,爱迪生发明了活动电影放映机,是早期电影显示设备,引入了电影放映的基本方法,通过在光源前使用发动机来高速转动带有连续图片的电影胶片条,从而产生活动的错觉,光源将胶片上的图片投射到银幕。
