pho·no·graph /ˈfonəˌgræf/
 留聲機,電唱機(vi.)灌入留聲機


 Pho·no·graph n.
 1. A character or symbol used to represent a sound, esp. one used in phonography. [archaic]
 2. Physics An instrument for the mechanical registration and reproduction of audible sounds, as articulate speech, etc. An early simple version consisted 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.  Modern versions use electronic circuitry and various more stable recording media to record sound more accurately.
