WIKIPEDIA:

A phonograph, later called a gramophone (as a trademark since 1887, as a generic name in the UK since 1910), and since the 1940s a record player, or more recently a turntable, is a device for the mechanical and analogue . The sound vibration 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 . To recreate the sound, the surface is similarly rotated while a playback (or "needle") traces the groove and is therefore vibrated by it, faintly reproducing the recorded sound. In early acoustic phonographs, the stylus vibrated a that produced sound waves coupled to the open air through a flaring , or directly to the listener's ears through -type earphones.

The phonograph was invented in 1877 by ; its use would rise the following year. 's made several improvements in the 1880s and introduced the '', including the use of wax-coated cardboard cylinders and a cutting stylus that moved from side to side in a zigzag groove around the record. In the 1890s, initiated the transition from to with a spiral groove running from the periphery to near the center, coining the term 'gramophone' for disc record players, which is predominantly used in many languages. Later improvements through the years included modifications to the turntable and its drive system, the or needle, pickup system, and the sound and systems.

The disc phonograph record was the dominant commercial audio distribution format throughout most of the 20th century, and phonographs became the first example of that people owned and used at their residences. In the 1960s, the use of and were introduced as alternatives. By 1987, phonograph use had declined sharply due to the popularity of cassettes and the rise of the . However, records have undergone a . This resurgence has much to do with vinyl records' sparing use of audio processing, resulting in a more natural sound on high-quality replay equipment, compared to many digital releases that are highly processed for portable players in high-noise environmental conditions. However, unlike "plug-and-play" digital audio, vinyl record players have user-serviceable parts, which require attention to tonearm alignment and the wear and choice of stylus, the most critical component affecting turntable sound.

Terminology

The terminology used to describe record-playing devices is not uniform across the English-speaking world. In modern contexts, the playback device is often referred to as a "turntable", "record player", or "". Each of these terms denotes distinct items. When integrated into a setup with a , turntables are colloquially known as "decks". In later versions of electric phonographs, commonly known since the 1940s as record players or turntables, the movements of the stylus are transformed into an by a . This signal is then converted back into sound through an and one or more .

The term "phonograph", meaning "sound writing", originates from the words φωνή (phonē, meaning 'sound' or 'voice') and γραφή (graphē, meaning 'writing'). Similarly, the terms "gramophone" and "graphophone" have roots in the Greek words γράμμα (gramma, meaning 'letter') and φωνή (phōnē, meaning 'voice').

In , "gramophone" may refer to any sound-reproducing machine that utilizes . These were introduced and popularized in the UK by the . Initially, "gramophone" was a proprietary of the company, and any use of the name by competing disc record manufacturers was rigorously challenged in court. However, in 1910, an English court decision ruled that the term had become generic;

United States An Edison Standard Phonograph that uses wax cylinders

In , "phonograph", properly specific to machines made by Edison, was sometimes used in a generic sense as early as the 1890s to include cylinder-playing machines made by others. But it was then considered strictly incorrect to apply it to 's Gramophone, a different machine that played nonrecordable discs (although Edison's original Phonograph patent included the use of discs.)

In , "record player" was the term; "turntable" was a more technical term; "gramophone" was restricted to the old mechanical (i.e., wind-up) players; and "phonograph" was used as in . The "phonograph" was first demonstrated in Australia on 14 June 1878 to a meeting of the by the Society's Honorary Secretary, who published "The Sounds of the Consonants, as Indicated by the Phonograph" in the Society's journal in November that year. On 8 August 1878 the phonograph was publicly demonstrated at the Society's annual conversazione, along with a range of other new inventions, including the .

Early history Phonautograph Main article:

The phonautograph was invented on March 25, 1857, by Frenchman , an editor and typographer of manuscripts at a scientific publishing house in Paris. One day while editing Professor Longet's Traité de Physiologie, he happened upon that customer's engraved illustration of the anatomy of the human ear, and conceived of "the imprudent idea of photographing the word." In 1853 or 1854 (Scott cited both years) he began working on "le problème de la parole s'écrivant elle-même" ("the problem of speech writing itself"), aiming to build a device that could replicate the function of the human ear.

Dictionary illustration of a . This version uses a barrel made of .

Scott coated a plate of glass with a thin layer of . He then took an acoustic trumpet, and at its tapered end affixed a thin membrane that served as the analog to the . At the center of that membrane, he attached a rigid boar's bristle approximately a centimetre long, placed so that it just grazed the lampblack. As the glass plate was slid horizontally in a well formed groove at a speed of one meter per second, a person would speak into the trumpet, causing the membrane to vibrate and the stylus to trace figures that were scratched into the lampblack. On March 25, 1857, Scott received the French patent #17,897/31,470 for his device, which he called a phonautograph. The earliest known surviving recorded sound of a human voice was conducted on April 9, 1860, when Scott recorded someone singing the song "" ("By the Light of the Moon") on the device. However, the device was not designed to play back sounds, as Scott intended for people to read back the tracings, which he called phonautograms. This was not the first time someone had used a device to create direct tracings of the vibrations of sound-producing objects, as had been used in this way by English physicist in 1807. By late 1857, with support from the Société d'encouragement pour l'industrie nationale, Scott's phonautograph was recording sounds with sufficient precision to be adopted by the scientific community, paving the way for the nascent science of acoustics.

The device's true significance in the history of recorded sound was not fully realized prior to March 2008, when it was discovered and resurrected in a Paris patent office by First Sounds, an informal collaborative of American audio historians, recording engineers, and sound archivists founded to make the earliest sound recordings available to the public. The phonautograms were then digitally converted by scientists at the in California, who were able to play back the recorded sounds, something Scott had never conceived of. Prior to this point, the earliest known record of a human voice was thought to be an 1877 phonograph recording by . The phonautograph would play a role in the development of the , whose inventor, Emile Berliner, worked with the phonautograph in the course of developing his own device.

Paleophone

, a French poet and amateur scientist, is the first person known to have made the conceptual leap from recording sound as a traced line to the theoretical possibility of reproducing the sound from the tracing and then to devising a definite method for accomplishing the reproduction. On April 30, 1877, he deposited a sealed envelope containing a summary of his ideas with the , a standard procedure used by scientists and inventors to establish of unpublished ideas in the event of any later dispute.

An account of his invention was published on October 10, 1877, by which date Cros had devised a more direct procedure: the recording stylus could scribe its tracing through a thin coating of acid-resistant material on a metal surface and the surface could then be etched in an acid bath, producing the desired groove without the complication of an intermediate photographic procedure. The author of this article called the device a phonographe, but Cros himself favored the word paleophone, sometimes rendered in French as voix du passé ('voice of the past').[]

Cros was a poet of meager means, not in a position to pay a machinist to build a working model, and largely content to bequeath his ideas to the free of charge and let others reduce them to practice, but after the earliest reports of Edison's presumably independent invention crossed the Atlantic he had his sealed letter of April 30 opened and read at the December 3, 1877 meeting of the French Academy of Sciences, claiming due scientific credit for priority of conception.

Throughout the first decade (1890–1900) of commercial production of the earliest crude disc records, the direct acid-etch method first invented by Cros was used to create the metal master discs, but Cros was not around to claim any credit or to witness the humble beginnings of the eventually rich phonographic library he had foreseen. He had died in 1888 at the age of 45.

The early phonographs for Edison's phonograph, May 18, 1880

conceived the principle of recording and reproducing sound between May and July 1877 as a byproduct of his efforts to "play back" recorded messages and to automate speech sounds for transmission by . His first experiments were with waxed paper. He announced his invention of the first phonograph, a device for recording and replaying sound, on November 21, 1877 (early reports appear in and several newspapers in the beginning of November, and an even earlier announcement of Edison working on a "talking-machine" can be found in the on May 9), and he demonstrated the device for the first time on November 29 (it was on February 19, 1878, as US Patent 200,521). "In December, 1877, a young man came into the office of the Scientific American, and placed before the editors a small, simple machine about which few preliminary remarks were offered. The visitor without any ceremony whatever turned the crank, and to the astonishment of all present the machine said: 'Good morning. How do you do? How do you like the phonograph?' The machine thus spoke for itself, and made known the fact that it was the phonograph..."

Close up of the mechanism of an Edison Amberola, c. 1915

The music critic attended an early demonstration (1881–82) of a similar machine. On the early phonograph's reproductive capabilities he wrote in retrospect: "It sounded to my ear like someone singing about half a mile away, or talking at the other end of a big hall; but the effect was rather pleasant, save for a peculiar nasal quality wholly due to the mechanism, although there was little of the scratching that later was a prominent feature of the flat disc. Recording for that primitive machine was a comparatively simple matter. I had to keep my mouth about six inches away from the horn and remember not to make my voice too loud if I wanted anything approximating to a clear reproduction; that was all. When it was played over to me and I heard my own voice for the first time, one or two friends who were present said that it sounded rather like mine; others declared that they would never have recognised it. I daresay both opinions were correct."

newspaper from Melbourne, Australia, reported on an 1878 demonstration at the , writing "There was a large attendance of ladies and gentlemen, who appeared greatly interested in the various scientific instruments exhibited. Among these the most interesting, perhaps, was the trial made by Mr. Sutherland with the phonograph, which was most amusing. Several trials were made, and were all more or less successful. 'Rule Britannia' was distinctly repeated, but great laughter was caused by the repetition of the convivial song of 'He's a jolly good fellow,' which sounded as if it was being sung by an old man of 80 with a cracked voice."

Edison's early phonographs recorded onto a thin sheet of metal, normally , which was temporarily wrapped around a grooved mounted on a correspondingly supported by plain and threaded . While the cylinder was rotated and slowly progressed along its , the airborne vibrated a connected to a stylus that indented the foil into the cylinder's groove, thereby recording the vibrations as "hill-and-dale" variations of the depth of the indentation.

By 1890, record manufacturers had begun using a rudimentary duplication process to mass-produce their product. While the live performers recorded the master phonograph, up to ten tubes led to blank cylinders in other phonographs. Until this development, each record had to be custom-made. Before long, a more advanced -based process made it possible to simultaneously produce 90–150 copies of each record. However, as demand for certain records grew, popular artists still needed to re-record and re-re-record their songs. Reportedly, the medium's first major African-American star was obliged to perform his "" (or the separate "The Whistling Coon") up to thousands of times in a studio during his recording career. Sometimes he would sing "The Laughing Song" more than fifty times in a day, at twenty cents per rendition. (The average price of a single cylinder in the mid-1890s was about fifty cents.)[]

Oldest surviving recordings Early phonograph at Deaf Smith County Historical Museum in ,

's cylinder recording for an experimental talking clock is often identified as the oldest surviving playable sound recording, although the evidence advanced for its early date is controversial. Wax recordings of 's choral music made on June 29, 1888, at in London were thought to be the oldest-known surviving musical recordings, until the recent playback by a group of American historians of a recording of recorded on April 9, 1860.

The 1860 phonautogram had not until then been played, as it was only a transcription of sound waves into graphic form on paper for visual study. Recently developed optical scanning and image processing techniques have given new life to early recordings by making it possible to play unusually delicate or physically unplayable media without physical contact.

A recording made on a sheet of tinfoil at an 1878 demonstration of Edison's phonograph in St. Louis, Missouri, has been played back by optical scanning and digital analysis. A few other early tinfoil recordings are known to survive, including a slightly earlier one that is believed to preserve the voice of U.S. President , but as of May 2014 they have not yet been scanned.[] These antique tinfoil recordings, which have typically been stored folded, are too fragile to be played back with a stylus without seriously damaging them. Edison's 1877 tinfoil recording of Mary Had a Little Lamb, not preserved, has been called the first instance of .

On the occasion of the 50th anniversary of the phonograph, Edison recounted reciting Mary Had a Little Lamb to test his first machine. The 1927 event was filmed by an early camera, and an audio clip from that film's soundtrack is sometimes mistakenly presented as the original 1877 recording. Wax cylinder recordings made by 19th-century media legends such as and Shakespearean actor are amongst the earliest verified recordings by the famous that have survived to the present.

Improvements at the Volta Laboratory Main article:

and his two associates took Edison's phonograph and modified it considerably to make it reproduce sound from wax instead of tinfoil. They began their work at Bell's in Washington, D. C., in 1879, and continued until they were granted basic patents in 1886 for recording in wax.

Although Edison had in 1877, the fame bestowed on him for this invention was not due to its efficiency. Recording with his tinfoil phonograph was too difficult to be practical, as the tinfoil tore easily, and even when the stylus was properly adjusted, its reproduction of sound was distorted, and good for only a few playbacks; nevertheless Edison had discovered the idea of . However immediately after his discovery he did not improve it, allegedly because of an agreement to spend the next five years developing the system.

Volta's early challenge

Meanwhile, Bell, a and experimenter at heart, was looking for new worlds to conquer after having patented the . According to , it was through that Bell took up the phonograph challenge. Bell had married in 1879 while Hubbard was president of the Edison Speaking Phonograph Co., and his organization, which had purchased the Edison patent, was financially troubled because people did not want to buy a machine that seldom worked well and proved difficult for the average person to operate.

Volta Graphophone See also: A 'G' (Graham Bell) model Graphophone being played back by a typist after its cylinder had recorded dictation.

The sound vibrations had been indented in the wax that had been applied to the Edison phonograph. The following was the text of one of their recordings: "There are more things in heaven and earth, Horatio, than are dreamed of in your philosophy. I am a Graphophone and my mother was a phonograph." Most of the disc machines designed at the Volta Lab had their disc mounted on vertical turntables. The explanation is that in the early experiments, the turntable, with disc, was mounted on the shop lathe, along with the recording and reproducing heads. Later, when the complete models were built, most of them featured vertical turntables.

One interesting exception was a horizontal seven inch turntable. The machine, although made in 1886, was a duplicate of one made earlier but taken to Europe by . Tainter was granted on July 10, 1888. The playing arm is rigid, except for a pivoted vertical motion of 90 degrees to allow removal of the record or a return to starting position. While recording or playing, the record not only rotated, but moved laterally under the stylus, which thus described a spiral, recording 150 grooves to the inch.

The basic distinction between the Edison's first phonograph patent and the Bell and Tainter patent of 1886 was the method of recording. Edison's method was to indent the sound waves on a piece of tin foil, while Bell and Tainter's invention called for cutting, or "engraving", the sound waves into a wax record with a sharp recording stylus.

In 1885, when the Volta Associates were sure that they had a number of practical inventions, they filed applications and began to seek out investors. The of Alexandria, Virginia, was created on January 6, 1886, and incorporated on February 3, 1886. It was formed to control the patents and to handle the commercial development of their sound recording and reproduction inventions, one of which became the first .

After the Volta Associates gave several demonstrations in the City of Washington, businessmen from created the on March 28, 1887, in order to produce and sell the machines for the budding phonograph marketplace. The Volta Graphophone Company then merged with American Graphophone, which itself later evolved into .

A coin-operated version of the Graphophone, , was developed by Tainter in 1893 to compete with nickel-in-the-slot entertainment phonograph demonstrated in 1889 by Louis T. Glass, manager of the Pacific Phonograph Company.

The work of the Volta Associates laid the foundation for the successful use of in business, because their wax recording process was practical and their machines were durable. But it would take several more years and the renewed efforts of Edison and the further improvements of and many others, before the became a major factor in .

Disc vs. cylinder as a recording medium

Discs are not inherently better than cylinders at providing audio fidelity. Rather, the advantages of the format are seen in the manufacturing process: discs can be stamped, and the matrixes to stamp disc can be shipped to other printing plants for a global distribution of recordings; cylinders could not be stamped until 1901–1902, when the gold moulding process was introduced by Edison.

A Victor V phonograph, circa 1907

Through experimentation, in 1892 Berliner began commercial production of his disc records and "gramophones". His "" was the first disc record to be offered to the public. They were five inches (13 cm) in diameter and recorded on one side only. Seven-inch (17.5 cm) records followed in 1895. Also in 1895 Berliner replaced the hard rubber used to make the discs with a compound. Berliner's early records had poor sound quality, however. Work by eventually improved the sound fidelity to a point where it was as good as the cylinder.

Dominance of the disc record A 1930s portable wind-up gramophone from ()

In the 1930s, (originally known as vinylite) was introduced as a record material for radio , and for radio commercials. At that time, virtually no discs for home use were made from this material. Vinyl was used for the popular 78-rpm issued to US soldiers during . This significantly reduced breakage during transport. The first commercial vinylite record was the set of five 12" discs "" (Asch Records album S-800, dubbed from Soviet masters in 1945). Victor began selling some home-use vinyl 78s in late 1945; but most 78s were made of a compound until the 78-rpm format was completely phased out. (Shellac records were heavier and more brittle.) 33s and 45s were, however, made exclusively of vinyl, with the exception of some 45s manufactured out of .

First all-transistor phonograph Philco all-transistor model TPA-1 phonograph, developed and produced in 1955 Philco all-transistor model TPA-1 phonograph – Radio and Television News magazine, issue October 1955

In 1955, developed and produced the world's first all- phonograph models TPA-1 and TPA-2, which were announced in the June 28, 1955 edition of . Philco started to sell these all-transistor phonographs in the fall of 1955, for the price of $59.95. The October 1955 issue of Radio & Television News magazine (page 41), had a full page detailed article on Philco's new consumer product. The all-transistor portable phonograph TPA-1 and TPA-2 models played only 45rpm records and used four 1.5 volt "D" batteries for their power supply. The "TPA" stands for "Transistor Phonograph Amplifier". Their circuitry used three Philco germanium PNP alloy-fused junction audio frequency transistors. After the 1956 season had ended, Philco decided to discontinue both models, for transistors were too expensive compared to vacuum tubes, but by 1961 a $49.95 ($509.29 in 2023) portable, battery-powered radio-phonograph with seven transistors was available.

Turntable designs A

There are presently three main phonograph designs: , , and .

In a belt-drive turntable the is located off-center from the platter, either underneath it or entirely outside of it, and is connected to the platter or counter-platter by a made from material.

The direct-drive turntable was invented by Shuichi Obata, an engineer at (now Panasonic). In 1969, Matsushita released it as the SP-10, the first direct-drive turntable on the market. The most influential direct-drive turntable was the , which, following the spread of in culture, became the most widely-used turntable in DJ culture for several decades.

Arm systems A 3012 tonearm fitted on a TD124 MkII turntable

In some high quality equipment the arm carrying the pickup, known as a tonearm, is manufactured separately from the motor and turntable unit. Companies specialising in the manufacture of tonearms include the English company .

Cue lever

More sophisticated turntables were (and still are) frequently manufactured so as to incorporate a "cue lever", a device that mechanically lowers the tonearm on to the record. It enables the user to locate an individual track more easily, to pause a record, and to avoid the risk of scratching the record, which may require practice to avoid when lowering the tonearm manually.

Linear tracking

Early developments in linear turntables were from Rek-O-Kut (portable lathe/phonograph) and Ortho-Sonic in the 1950s, and Acoustical in the early 1960s. These were eclipsed by more successful implementations of the concept from the late 1960s through the early 1980s.

Pickup systems Typical magnetic cartridge

The pickup or cartridge is a that converts mechanical vibrations from a stylus into an electrical signal. The electrical signal is and converted into sound by one or more . Crystal and ceramic pickups that use the have largely been replaced by .

The pickup includes a stylus with a small or tip that runs in the record groove. The stylus eventually becomes worn by contact with the groove, and it is usually replaceable.

Styli are classified as spherical or elliptical, although the tip is actually shaped as a half-sphere or a half-. Spherical styli are generally more robust than other types, but do not follow the groove as accurately, giving diminished high frequency response. Elliptical styli usually track the groove more accurately, with increased high frequency response and less distortion. For DJ use, the relative robustness of spherical styli make them generally preferred for back-cuing and scratching. There are a number of derivations of the basic elliptical type, including the shibata or fine line stylus, which can more accurately reproduce high frequency information contained in the record groove. This is especially important for playback of quadraphonic recordings.

Optical readout

A few specialist read the groove optically using a laser pickup. Since there is no physical contact with the record, no wear is incurred. However, this "no wear" advantage is debatable, since vinyl records have been tested to withstand even 1200 plays with no significant audio degradation, provided that it is played with a high quality cartridge and that the surfaces are clean.

An alternative approach is to take a high-resolution photograph or scan of each side of the record and interpret the image of the grooves using . An amateur attempt using a flatbed scanner lacked satisfactory fidelity. A professional system employed by the produces excellent quality.

Stylus Stylus for using 78 rpm records, 1940s

A development in stylus form came about by the attention to the sound modulation process, which requires up to 50 kHz frequency response, with cartridges like EPC-100CMK4 capable of playback on frequencies up to 100 kHz. This requires a stylus with a narrow side radius, such as 5 μm (or 0.2 ). A narrow-profile elliptical stylus is able to read the higher frequencies (greater than 20 kHz), but at an increased wear, since the contact surface is narrower. For overcoming this problem, the Shibata stylus was invented around 1972 in Japan by Norio Shibata of JVC.

The Shibata-designed stylus offers a greater contact surface with the groove, which in turn means less pressure over the vinyl surface and thus less wear. A positive side effect is that the greater contact surface also means the stylus reads sections of the vinyl that were not touched (or "worn") by the common spherical stylus. In a demonstration by JVC records "worn" after 500 plays at a relatively high 4.5 gf tracking force with a spherical stylus, played "as new" with the Shibata profile.[]

Other advanced stylus shapes appeared following the same goal of increasing contact surface, improving on the Shibata. Chronologically: "Hughes" Shibata variant (1975), "Ogura" (1978), Van den Hul (1982). Such a stylus may be marketed as "Hyperelliptical" (Shure), "Alliptic", "Fine Line" (Ortofon), "Line contact" (Audio Technica), "Polyhedron", "LAC", or "Stereohedron" (Stanton).

A keel-shaped diamond stylus appeared as a byproduct of the invention of the . This, together with laser-diamond-cutting technologies, made possible the "ridge" shaped stylus, such as the Namiki (1985) design, and Fritz Gyger (1989) design. This type of stylus is marketed as "MicroLine" (Audio technica), "Micro-Ridge" (Shure), or "Replicant" (Ortofon).

To address the problem of steel needle wear upon , which resulted in the cracking of the latter, devised unbreakable records in 1930, by mixing polyvinyl chloride with plasticisers, in a proprietary formula they called Victrolac, which was first used in 1931, in motion picture discs.

Equalization Since the late 1950s, almost all phono input stages have used the RIAA equalization standard. Before settling on that standard, there were many different equalizations in use, including EMI, HMV, Columbia, Decca FFRR, NAB, Ortho, BBC transcription, etc. Recordings made using these other equalization schemes typically sound odd if they are played through a RIAA-equalized preamplifier. High-performance (so-called "multicurve disc") preamplifiers, which include multiple, selectable equalizations, are no longer commo
