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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stroh Violin
The Stroh violin or Stroviol is a type of String instrument, 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. Johannes Matthias Augustus Stroh, an electrical engineer from Frankfurt, invented the instrument in London 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phonograph
A phonograph, later called a gramophone, and since the 1940s a record player, or more recently a turntable, is a device for the mechanical and analogue reproduction of sound. The sound vibration Waveform, waveforms are recorded as corresponding physical deviations of a helical or spiral groove engraved, etched, incised, or impressed into the surface of a rotating cylinder or disc, called a ''Phonograph record, record''. To recreate the sound, the surface is similarly rotated while a playback #Stylus, stylus traces the groove and is therefore vibrated by it, faintly reproducing the recorded sound. In early acoustic phonographs, the stylus vibrated a Diaphragm (acoustics), diaphragm that produced sound waves coupled to the open air through a flaring Horn loudspeaker, horn, or directly to the listener's ears through stethoscope-type earphones. The phonograph was invented in 1877 by Thomas Edison; its use would rise the following year. Alexander Graham Bell's Volta Laboratory an ...

Mica
Micas ( ) are a group of silicate minerals whose outstanding physical characteristic is that individual mica crystals can easily be split into fragile 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, and fillers, especially in parts for automobiles, roofing, and in electronics. The mineral is used in cosmetics and food to add "shimmer" or "frost". Properties and structure The mica group comprises 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 translucent to opa ...

Acoustic Recording
A phonograph record (also known as a gramophone record, especially in British English) or a vinyl record (for later varieties only) is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the outside edge and ends near the center of the disc. The stored sound information is made audible by playing the record on a phonograph (or "gramophone", "turntable", or "record player"). Records have been produced in different formats with playing times ranging from a few minutes to around 30 minutes per side. For about half a century, the discs were commonly made from shellac and these records typically ran at a rotational speed of 78 rpm, giving it the nickname "78s" ("seventy-eights"). After the 1940s, "vinyl" records made from polyvinyl chloride (PVC) became standard replacing the old 78s and remain so to this day; they have since been produced in various sizes and speeds, most commonly 7-inch discs pla ...

The Temperance Seven
The Temperance Seven is a British band originally active in the 1950s, 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 Dougie Gray, of the Alberts. In 1960, they recorded "Ukulele Lady" with vocal refrain by Peter Sellers, produced by George Martin. It was featured on Parlophone PMC 1131, a 12-inch album called ''Peter and Sophia'' (Loren). In 1961, the Temperan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
