湯瑪斯‧愛迪生 (Thomas Edison) 和第一部留聲機

下一次你聽到一張喜歡的唱片，你應該要感謝湯瑪斯‧愛迪生發明錄製聲音的功勞。在還沒有光碟音響和錄音帶之前，只有留聲機可以放出音樂。1877年8月12日是大眾紀念湯瑪斯‧愛迪生完成第一部留聲機的日子

愛迪生本來是想要改善電報傳輸的方式，不過他注意到紙帶高速劃過機器時會發出微弱的聲音，很像是說話的聲音。經過運用唱針和錫瓶進行實驗，愛迪生對著機器說話。你知道最先錄製的話是什麼嗎？


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?
