汤玛斯．爱迪生 (Thomas Edison) 和第一部留声机

下一次你听到一张喜欢的唱片，你应该要感谢汤玛斯．爱迪生发明录制声音的功劳。在还没有光盘音响和录音带之前，只有留声机可以放出音乐。1877年8月12日是大众纪念汤玛斯．爱迪生完成第一部留声机的日子

爱迪生本来是想要改善电报传输的方式，不过他注意到纸带高速划过机器时会发出微弱的声音，很像是说话的声音。经过运用唱针和锡瓶进行实验，爱迪生对着机器说话。你知道最先录制的话是什么吗？


The next time you listen to a favorite album, you can thank Thomas Edison for discovering the secret to recording sound. Before there were CD players and tape decks, there was the phonograph. August 12, 1877 is the date popularly given for Thomas Edison's completion of the model for the first phonograph.

Edison was trying to improve the telegraph transmitter when he noticed that the movement of the paper tape through the machine produced a noise resembling spoken words when played at a high speed. Experimenting with a stylus (hard-pointed instrument like a large needle) on a tinfoil cylinder, Edison spoke into the machine. Do you know the first words ever recorded?
