Uku dug under the bed and returned with a case of graphophone ‘Columbia’ and a stack of vinyl gramophone records. Astonishing how loud noise can come out of an instrument with no electronics included. Only tool for any adjustment was the knob for adjusting the rotation speed. We could not find any way for adjusting the volume, which was actually rather loud.
As entertaining and nostalgic as it was it seemed to be obvious that the graphophone is just an interesting piece of antique with not much use today. One record lasted for about 3 minutes, which is average length of mp3 tracks You can already have hundreds in Your phone.
See the graphophone in action.
Turns out, the idea behind gramophone is not that antique and useless after all. Phonofone is based on similar powerless passive amplification designed to amplify sound from ..mp3 players and headsets! Information about Phonofone was mediated right on time for this post by[EST].
