Definition: A gramophone is a type of audio recording device that converts sound waves into electric signals, which are then amplified and sent to the speakers. Gramophones typically have an electronic circuitry with 20 or more rotary switches that allow users to select different notes or tones for playback. The term "gramophone" comes from the English word "gram", meaning a small piece of wood used in making musical instruments, such as the violin or cello.
