Phonograph \Pho"no*graph\, n. [Phono- + -graph.]
   1. A character or symbol used to represent a sound, esp. one
      used in phonography.

   2. (Physics) An instrument for the mechanical registration
      and reproduction of audible sounds, as articulate speech,
      etc. It consists of a rotating cylinder or disk covered
      with some material easily indented, as tinfoil, wax,
      paraffin, etc., above which is a thin plate carrying a
      stylus. As the plate vibrates under the influence of a
      sound, the stylus makes minute indentations or undulations
      in the soft material, and these, when the cylinder or disk
      is again turned, set the plate in vibration, and reproduce
      the sound.
