据说，当亚历山大·贝尔还在十几岁时，电话的最早火花就来了。他注意到，如果他在露天钢琴附近唱着一张音符，那串音符会振动，好像在向他唱歌一样。他唱了一个A；绳子震动。通过电线连接声音的想法诞生了。但这不是一个新主意。我们呼唤；我们得到了回答。从信念的开始就一直如此，一直持续到这一刻
(It is said that the earliest spark for the telephone came when Alexander Bell was still in his teens. He noticed how, if he sang a certain note near an open piano, the string of that note would vibrate, as if singing back to him. He sang an A; the A string shook. The idea of connecting voices through a wire was born. But it was not a new idea. We call out; we are answered. It has been that way from the beginning of belief, and it continues to this very moment)
