Wharfedale (company)
Wharfedale is a Chinese audio equipment manufacturer best known for loudspeakers. It is currently part of the International Audio Group. Wharfedale also used to brand televisions, DVD players, set-top boxes and Mini-System, Hi-Fi players. Since 2008, they have only manufactured and sold audio equipment. History Wharfedale Wireless Works was founded in 1932 by Gilbert Briggs, and became one of Britain's leading manufacturers of audiophile equipment, particularly loudspeakers. In addition to winning awards by groups such as the Bradford Radio Society, in mass public testing at Carnegie Hall Wharfedale speakers proved indistinguishable from live music. Innovations introduced by Wharfedale under Briggs included such basics as the Audio crossover#Classification based on the number of filter sections, two-way Loudspeaker#Multi driver systems, loudspeaker and the ceramic magnet. In the 1950s and 1960s, Wharfedale became famous for its technique of eliminating cabinet resonances by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Resonance
Resonance describes the phenomenon of increased amplitude that occurs when the frequency of an applied periodic force (or a Fourier component of it) is equal or close to a natural frequency of the system on which it acts. When an oscillating force is applied at a resonant frequency of a dynamic system, the system will oscillate at a higher amplitude than when the same force is applied at other, non-resonant frequencies. Frequencies at which the response amplitude is a relative maximum are also known as resonant frequencies or resonance frequencies of the system. Small periodic forces that are near a resonant frequency of the system have the ability to produce large amplitude oscillations in the system due to the storage of vibrational energy. Resonance phenomena occur with all types of vibrations or waves: there is mechanical resonance, orbital resonance, acoustic resonance, electromagnetic resonance, nuclear magnetic resonance (NMR), electron spin resonance (ESR) and reso ...

Electronics Companies Established In 1932
The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using Electronic component, electronic devices. Electronics uses Passivity (engineering), active devices to control Electric current, electron flow by Amplifier, amplification and Rectifier, rectification, which distinguishes it from classical electrical engineering, which only uses Passive electronic component, passive effects such as Electrical resistance and conductance, resistance, capacitance and inductance to control electric current flow. Electronics has hugely influenced the development of modern society. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $481 billion as of 2018. The largest industry sector is e-commerce, which generated over $29 trillion in 2017. History and development Electronics has hugely influenced the development of modern s ...

Manufacturing Companies Based In Bradford
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed into a final product. T ...

Idle, West Yorkshire
Idle is a residential suburban area in the city of Bradford, West Yorkshire, in England and was a separate village, and before that it was the Manor of Idle. Idle is loosely bordered by the areas of Eccleshill, Wrose, Thackley, Apperley Bridge, and Greengates, in the north-east of the city. History The Manor of Idle contained the villages of Idle and Windhill and hamlets of Thackley, Thorpe-Green, Parkhill, Cross-Keys, Buckmill, and Wrose. The Manor of Idle was bounded by the River Aire in the north and in the east Pighill Beck (now named Haigh Beck) up to Blakehill Tongue and across westwards down a small beck to Bradford Beck. The name is thought to be a corruption of ''Idlawe'' meaning Ide's Hill, where Ida is supposed to be an Anglo Saxon settler. Thorpe middle school is in the centre of the village. Church history Idle was once part of the parish of Calverley but in 1584 a chapel of ease was built on Town Lane and later in 1630 rebuilt on the same site. The buildin ...

Argos (retailer)
Argos Limited, trading as Argos, is a catalogue retailer operating in the United Kingdom and Ireland, acquired by Sainsbury's supermarket chain in 2016. It was established in November 1972 and is named after the Greek city of Argos, Peloponnese, Argos. The company trades both through physical shops and online, with 29 million yearly shop customers, and nearly a billion online visitors per annum. It has also franchised overseas to countries such as China. History The company was founded by Richard Tompkins who had previously established Green Shield Stamps in the United Kingdom. He came up with the idea that people could purchase goods from his "Green Shield Gift House" with cash rather than savings stamps. He rebranded the original Green Shield Stamps catalogue shops as ''Argos'' beginning in July 1973, the first purpose-built shop opening on the A28 road, A28 Sturry Road, Canterbury in late 1973. Green Shield House was in Station Road, Edgware. Argos was launched with thousand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sand
Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass. The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz. Calcium carbonate is the second most common type of sand, for example, aragonite, which has mostly been created, over the past 500million years, by various forms of life, like coral and shellfish. For example, it is the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years like the Caribbean. Somewhat more rarely, sand may be composed of calciu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceramic Magnet
A ferrite is a ceramic material made by mixing and firing large proportions of iron(III) oxide (Fe2O3, rust) blended with small proportions of one or more additional metallic elements, such as strontium, barium, manganese, nickel, and zinc. They are ferrimagnetic, meaning they can be magnetized or attracted to a magnet. Unlike other ferromagnetic materials, most ferrites are not electrically conductive, making them useful in applications like magnetic cores for transformers to suppress eddy currents. Ferrites can be divided into two families based on their resistance to being demagnetized (magnetic coercivity). Hard ferrites have high coercivity, so are difficult to demagnetize. They are used to make permanent magnets for applications such as refrigerator magnets, loudspeakers, and small electric motors. Soft ferrites have low coercivity, so they easily change their magnetization and act as conductors of magnetic fields. They are used in the electronics industry to make effici ...
