| The most prominent feature of the early phonographs was the horn, or bell, a megaphone-shaped extension used to focus and amplify the sound. Phonograph recordings were initially made on tinfoil wrapped around the recording drum. However, the foil only held a few minutes of sound and wore out quickly. It was replaced with the more durable wax cylinder. This model was designed by Thomas Edison in 1905. It features the “new” wax cylinder as well as a sapphire stylus. | ||||||
