Edison's phonograph involved a cylinder covered in a thin sheet of tin foil. Sound was collected by a horn, which caused a diaphragm to vibrate. This was connected to an arm, so when the diaphragm vibrated (because of the sounds) - indents or grooves were made on the foil. This "stored" the sound. In order to playback the sound - the arm went over the grooves, causing the diaphragm to vibrate in the same way it had before. These vibrations reproduced the original sound.
