The Most Popular Music Playing Devises. By: Thomas Savell and Savannah Nimpfer Class: 3B
The Record Player!!! • Was invented in 1877 by Thomas Edison. • The record player used a needle, that was attached to a magnet. The needle would read the groves in the record which would produce a series of sounds, that would vibrate which then would be translated and amplified by a horn like speaker. • Originally tin foil was used for the recording but later was changed to a flask disk.
Record Player Continued!! • It was originally made with a funnel/speaker for amplifying the vibrations made by a series of coils. The coils would vibrate when the needle attached to a magnet would scratch against a plastic type of a record. • Many people at first it was used as a way to study the human language but then was discovered that it could play music which made it useable by everyone.
The Portable Cd Player • Was invented in 1984 by Sony Inc. • Originally the Cd player came with fast forward, rewind, play/pause, hold, stop, and liquid crystal display. • An anti-shock hardware was installed later to help stop skipping on Cds and then an electronic skip protection was also made to stop skipping too. • People of all ages.
