What are the motions of the phonograph?

Answer 1

That depends on if it plays cylinders or flat records. Or what paticular motions are considered. Here are the motions that most phonographs, gramophones, and victrolas include. 1. The crank is usually external and usually is hand-wound in a clockwise motion. 2. Internally the spring is wound tight and its loosening produces the force for the motion of the motor. 3. Gears under the influence of the spring power the governor, usually two or three weights on spring steel on a sliding spindle, their centrifugal force steadies the motion of the unwinding spring and there is usually a felt covered stop connected to a turn screw or lever that enables the user to set the speed at a particular RPM. 4. The governor controls the spin of the turntable which rotates on a horizontal plane as in disc records or in a clockwise motion of the spindle as in cylinder phonographs. 5. the arm of the phonograph is connected to the amplifying horn; and the reproducing head which moves across the record or cylinder usually from right to left if you are looking at the machine fromthe front. disc machine arms usually swing on a fixed pivot and cylinder machines usually have some sort of worm gear and half nut that move the head and arm horizontally across the cylinder. Some machines, such as the Edison disc phonograph, have a combination of central pivot and worm gear. One note, due to the experimental nature of phonographs in the early twentieth century, many variations of this basic arrangement I've described can and do exist.

Answer 2

The phonograph typically rotates the record at a constant speed while the stylus traces the grooves on the record, causing vibrations. These vibrations are then converted into electrical signals by the cartridge, which are then amplified and played back through speakers.
