CLPGS
The City of London Phonograph and Gramophone Society (CLPGS)In the United Kingdom, the term ' phonograph' is used for a player of cylinders, while a 'gramophone' plays disc records. In many other parts of the world the term 'phonograph' is used for both. is a British society and registered charity dedicated to the research in all aspects of early recorded sound. Founded in 1919, the CLPGS is likely to be the oldest society of its type in the world. History The CLPGS was founded under the name "The London Edison Society" in 1919, when Norman Hillyer and some members of the North London Phonograph and Gramophone Society decided that a group was needed within the City of London. The founding members agreed to approach Thomas Edison to ask if he would become a Patron of the new venture. Edison would only agree if the group changed its name to the City of London Phonograph Society, so this was done. The group's initial membership numbered about forty.

Phonograph A phonograph, in its later forms also called a gramophone (as a trademark since 1887, as a generic name in the UK since 1910) or since the 1940s called a record player, or more recently a turntable, is a device for the mechanical and analogue recording and reproduction of sound. The sound vibration waveforms are recorded as corresponding physical deviations of a spiral groove engraved, etched, incised, or impressed into the surface of a rotating cylinder or disc, called a "record". To recreate the sound, the surface is similarly rotated while a playback stylus traces the groove and is therefore vibrated by it, very faintly reproducing the recorded sound. In early acoustic phonographs, the stylus vibrated a diaphragm which produced sound waves which were coupled to the open air through a flaring horn, or directly to the listener's ears through stethoscope-type earphones. The phonograph was invented in 1877 by Thomas Edison. Alexander Gra |
