By 1913, phonographs had evolved from playing wax cylinders to the disc records we are familiar with today, which was cheaper and easier to store. Like the wax cylinders, disc records stored music in the ridges of the material, which is read with a needle.
Phonographs often have a horn (like the one here) attached to the side of it so that the sound is projected out into the room instead of just hanging above the device. The cone shape of the horn amplifies the sound without electricity.
