The Phonograph
The phonograph is a device that was used for playing sound recordings. The recordings played on such a device generally consisting of wavy lines that are either scratched, engraved, or grooved onto a rotating cylinder or disc. As the cylinder or disc rotates, a needle on the device traces the wavy lines and vibrates, reproducing sound waves. It was not until 1877 when thomas edison successfully conceived the principle of recording and reproducing sound, and demonstrated the phonograph for the first time. Edison's early devices recorded sound onto a tinfoil sheet phonograph cylinder. The idea of this invention led to many other inventions it aided in the production of movies, eventually popularizing music, as the technology was the baseline for record players which led to the the compact disc or cd which would be played in a "cd" player, which is used today. This invention greatly affected common life over time, movies and music became popular and still are today, this baseline invention has become a daily part of our life whether it be listening to a cd in your car to watching a movie, it has given a way to record history.
