A phonograph usually consists of:
-
a mandrel to hold a wax, celluloid or coated cardboard cylinder
- a motor to turn the mandrel at a constant speed. Usually spring driven, but could be directly hand wound, and in some cases equipped with an electric motor. The motor could be alongside the mandrel, so that you can see it functioning, or below it, encased usually in a wood case.
- a reproducer, usually a metal housing with a diaphram and a glass or sapphire stylus.
- a horn for amplifying the sound, usually in Brass or tin, but also wood, copper, papermache and even glass.
- a cabinet
that could take many forms. The most common resemble sewing machine cases where the mechanism is covered with a domed wooden lid when the machine is not in use. With some european machines , a style of reversible case was used where the machine and case flipped over into its case.
The variations in the way inventors approached the primary issue of moving a cylinder under a stylus and amplifying the sound, are many and varied, as you will see in the various
makes and models you see in the menu at the left of the screen.
