   A phonograph is another word for a record player. I have one at home as I still have my vinyl records collection.

   They are still in production and a lot of these are for those people who do those "scracthy' sounds for rap music.

   A phonograph is also known as a record player or turntable. At one time, all music was produced only on records. (This answer assumes that the word 'phonograph' is being used in the most traditional sense.)

   The phonograph was the way people used to play records. It has the large, trumpet shaped metal cone, which changes the vibrations engraved on the discs (or cylinders, depending on model) into sounds that we can hear (music, etc.). People would be interested in buying one for antique purposes, or possibly they posses some old records, or cylinders that they would like to play.

   Of course you'd want to buy one. It was the only way you would be able to hear records.
   The original phonograph was invented by Emile Berliner, and played a flat disc spinning (at about 80rpm and driven by a clockwork motor) about 7 inches in diameter with grooves (on one side only) that carried the music or the speech message.
   A cylinrical disc was available later on a machine built by Edison.
   About 1907, discs were available with grooves on both sides, and speed was standardised at 78 rpm. Discs were then either 10 or 12 inches in diameter.
   In 1947 Columbia Broadcasting introduced the microgroove record, 10 or 12 inches diameter which revolved at at 33 1/3 rpm. Then came the 7" single or minigroove record. The single has one track per side, the Extended Play minigroove has 2 or 3.
   If you didn't have a phonograph these records were useless.
   The CDs I bought in 1920, I had to stow away 'til the mid 90s before I could hear what was on them. Wow, what patience!
