Ortofon
__NOTOC__ Ortofon is a Danish manufacturer of electronic audio equipment. It is the world's largest producer of magnetic cartridges for phonograph turntables, with 500,000 cartridges sold annually. History Engineers Arnold Poulsen and Axel Petersen founded Ortofon in 1918. Initially focusing on sound film technology, Ortofon began to diversify into gramophone record playback and cutting equipment towards the end of World War II. The firm pioneered the use of moving coil technology in phonograph equipment; the first cutting head based on this technology was introduced in 1945. Ortofon's first moving coil magnetic cartridge, the AB model, was launched in 1948, and similar variations of that product are still manufactured today due to demand from enthusiasts. In 1959, the first Stereo Pick-Up ''SPU'', which aimed at professionals, appeared. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phonograph Manufacturers
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 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 '' record''. To recreate the sound, the surface is similarly rotated while a playback stylus traces the groove and is therefore vibrated by it, faintly reproducing the recorded sound. In early acoustic phonographs, the stylus vibrated a diaphragm that produced sound waves 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; its use would rise the following year. Alexander Graham Bell's Volta Laboratory made several improvements in the 1880s and introduced the graphophone, inclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Revox
ReVox (on-logo styling REVOX) is a brand name, registered by Studer on 27 March 1951 for Switzerland, Swiss audio equipment. History The first Studer-designed tape recorders were branded Dynavox. After the first production series of Dynavox recorders, a new marketing company was formed in 1950 called ELA AG. Revox was adopted as the brand name for amateur recorders, while the professional machines retained the Studer name. The first Revox-branded tape recorder was the T26, in 1952, successor to the Dynavox 100. The T26 was also made available as a radio-recorder combination unit. 2500 T26 recorders were made, priced at 1395.00 Swiss francs. The A36, the first 36 series recorder. became available in 1954.

Audio Equipment
Audio equipment refers to devices that reproduce, record, or process sound. This includes microphones, radio receivers, AV receivers, CD players, tape recorders, amplifiers, mixing consoles, effects units, headphones, and speakers. Audio equipment is widely used in many different scenarios, such as concerts, bars, meeting rooms and the home where there is a need to reproduce, record and enhance sound volume. Electronic circuits considered a part of audio electronics may also be designed to achieve certain signal processing operations, in order to make particular alterations to the signal while it is in the electrical form.Kadis, J. (2011). Introduction to sound recording technology. Informally published manuscript, Stanford Music Department: Center for Computer Research in Music and Acoustics, Stanford University, Stanford, California.

Audiophile
An audiophile (from + ) is a person who is enthusiastic about high-fidelity sound reproduction. The audiophile seeks to achieve high sound quality in the audio reproduction of recorded music, typically in a quiet listening space in a room with good acoustics. Audiophile values may be applied at all stages of music reproduction—the initial audio recording, the production process, the storage of sound data, and the playback (usually in a home setting). In general, the values of an audiophile are seen to be antithetical to the growing popularity of more convenient but lower-quality music, especially lossy digital file types like MP3, lower-definition music streaming services, laptop or cell phone speakers, and low-cost headphones. The term '' high-end audio'' refers to playback equipment used by audiophiles, which may be bought at specialist shops and websites. High-end components include turntables, digital-to-analog converters, equalization devices, preamplifiers and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electronics Companies Established In 1918
Electronics is a scientific and engineering discipline that studies and applies the principles of physics to design, create, and operate devices that manipulate electrons and other electrically charged particles. It is a subfield of physics and electrical engineering which uses active devices such as transistors, diodes, and integrated circuits to control and amplify the flow of electric current and to convert it from one form to another, such as from alternating current (AC) to direct current (DC) or from analog signals to digital signals. Electronic devices have significantly influenced the development of many aspects of modern society, such as telecommunications, entertainment, education, health care, industry, and security. The main driving force behind the advancement of electronics is the semiconductor industry, which continually produces ever-more sophisticated electronic devices and circuits in response to global demand. The semiconductor industry is one of the global ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO 13485
ISO 13485 ''Medical devices -- Quality management systems -- Requirements for regulatory purposes'' is a voluntary standard, published by International Organization for Standardization (ISO) for the first time in 1996, and contains a comprehensive quality management system for the design and manufacture of medical devices. The latest version of this standard supersedes earlier documents such as EN 46001 (1993 and 1996) and EN 46002 (1996), the previously published ISO 13485 (1996 and 2003), and ISO 13488 (also 1996). The current ISO 13485 edition was published on 1 March 2016. Background Though it is tailored to the industry's quality system expectations and regulatory requirements, an organization does not need to be actively manufacturing medical devices or their components to seek certification to this standard, in contrast to the automotive sector's ISO/TS 16949, where only firms with an active request for quotation, or on the bid list, of an International Automotive Task ...

Thermoplastic Elastomer
Thermoplastic elastomers (TPE), sometimes referred to as thermoplastic rubbers (TPR), are a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) that consist of materials with both thermoplastic and elastomeric properties. While most elastomers are thermosets, thermoplastic elastomers are not, in contrast making them relatively easy to use in manufacturing, for example, by injection moulding. Thermoplastic elastomers show advantages typical of both rubbery materials and plastic materials. The benefit of using thermoplastic elastomers is the ability to stretch to moderate elongations and return to its near original shape creating a longer life and better physical range than other materials. The principal difference between thermoset elastomers and thermoplastic elastomers is the type of cross-linking bond in their structures. In fact, crosslinking is a critical structural factor which imparts high elastic properties. Types There are six g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
