Phonofiddle
A phonofiddle is a class of stringed musical instruments that are played with a bow and use a phonograph type reproducer as a voice-box. The sound producing diaphragm may be a metal cone as in the Stroh violin or a mica sheet as in the instruments made by A. T. Howson, London and the Stroviols company of Britain. The sound generated by the vibrations from the string or strings are transferred through the bridge to a connecting arm into the center of the diaphragm within the reproducer. The vibrating column of air is then directed into one or several horns. On 4 May 1899, Johannes Matthias Augustus Stroh applied for a patent in Great Britain, GB9418 titled ''Improvements in Violins and other Stringed Instruments'' which was accepted on 24 March 1900. This described the use of a flat metal (other materials are also mentioned) diaphragm in the voice-box (reproducer) of a violin to mechanically amplify the sound. Then on 16 February 1901 he applied for a second Great British patent, G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stroh Violin
The Stroh violin or Stroviol is a type of stringed musical instrument that is mechanically amplified by a metal resonator and horn attached to its body. The name Stroviol refers to a violin, but other instruments have been modified with the amplification device, including the viola, cello, double bass, ukulele, mandolin, and guitar. John Matthias Augustus Stroh, an electrical engineer in London, invented the instrument in 1899. Description The Stroh violin has a horn at the end of the fingerboard to project the sound to an audience or recording horn, and often a smaller monitoring horn that the performer placed at their ear to hear what was being played more distinctly. The Stroh violin is much louder than a standard wooden violin, and its directional projection of sound made it particularly useful in the early days of phonographic recording. Wooden violins recorded poorly with the early acoustic-mechanical recording method, and the Stroh violin improved this by producin ...

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 Graham Bell's Volta Laboratory made s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mica
Micas ( ) are a group of silicate minerals whose outstanding physical characteristic is that individual mica crystals can easily be split into extremely thin elastic plates. This characteristic is described as perfect basal cleavage. Mica is common in igneous and metamorphic rock and is occasionally found as small flakes in sedimentary rock. It is particularly prominent in many granites, pegmatites, and schists, and "books" (large individual crystals) of mica several feet across have been found in some pegmatites. Micas are used in products such as drywalls, paints, fillers, especially in parts for automobiles, roofing and shingles, as well as in electronics. The mineral is used in cosmetics and food to add "shimmer" or "frost." Properties and structure The mica group is composed of 37 phyllosilicate minerals. All crystallize in the monoclinic system, with a tendency towards pseudohexagonal crystals, and are similar in structure but vary in chemical composition. Micas are ...

Acoustic Recording
A phonograph record (also known as a gramophone record, especially in British English), or simply a record, is an analog signal, analog sound Recording medium, storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the periphery and ends near the center of the disc. At first, the discs were commonly made from shellac, with earlier records having a fine abrasive filler mixed in. Starting in the 1940s polyvinyl chloride became common, hence the name vinyl. The phonograph record was the primary medium used for music reproduction throughout the 20th century. It had co-existed with the phonograph cylinder from the late 1880s and had effectively superseded it by around 1912. Records retained the largest market share even when new formats such as the compact cassette were mass-marketed. By the 1980s, digital audio, digital media, in the form of the compact disc, had gained a larger market share, and the record left the main ...

The Temperance Seven
The Temperance Seven is a British band originally active in the 1960s, specialising in 1920s-style jazz music. They were known for their surreal performances. Career The Temperance Seven was founded at Christmas 1955 by students at the Chelsea School of Art, though the band mythologized its foundation as dating from 1904 at the fictitious Pasadena Cocoa Rooms, Balls Pond Road, North London. The three founder members were Paul McDowell (who originally played trombone), Philip Harrison (who originally played banjo) and Brian Innes (drums). Gradually the band evolved into a nine-piece ensemble with a light-hearted and humorous performing style, although they were all serious musicians. The name "Temperance Seven" was suggested by Douggie Gray, of the Alberts fame. The Alberts were cult figures in the art scene in the mid 1950s and were forerunners of the sort of humour that became Monty Python. (This was not the band's only link with Monty Python; see below).
