Magnepan
Magnepan is a private high-end audio loudspeaker manufacturer in White Bear Lake, Minnesota, United States. Their loudspeaker technology was conceived and implemented by engineer Jim Winey in 1969. Overview Magnepan's speaker design, sold under the brand name Magneplanar (often referred to as "Maggies"), differs from that of conventional speakers in relying not on cones mounted in an enclosure, but on a planar driver system mounted in a panel. A Magneplanar's reproducing mechanism (magnetostatic loudspeaker) comprises thin conductive wires and or foil strips attached to a thin sheet of Mylar residing in a magnetic field created by a vertical array of permanent strip magnets. When an electric signal is applied to the conductors, the resultant electric current moving through the magnetic field applies a force to the wires or tape, moving the Mylar film sheet, which projects sound as a dipole. In principle, this approach relies on the same concept as a voice coil-driven cone speak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Magnetostatic Loudspeaker
A magnetostatic loudspeaker is a dipole loudspeaker that is similar to an electrostatic loudspeaker but uses high currents instead of using high voltages. Permanent magnets provide a static magnetic field and wires or strips carrying audio frequency currents are bonded to a thin diaphragm. The current flowing in the conductors interacts with the magnetic field and creates sound in much the same way as in a conventional dynamic driver. Because of its dipole structure, this kind of speaker creates sound mostly to its front and back. The impedance of a magnetostatic speaker is often mainly resistive, but in some cases may be so low that the amplifiers An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a signal (a time-varying voltage or current). It may increase the power significantly, or its main effect may be to boost the v ... have to be ready to accommodate the low impedance load. Magnetostatic speakers p ...

Electrostatic Loudspeakers
An electrostatic loudspeaker (ESL) is a loudspeaker design in which sound is generated by the force exerted on a membrane suspended in an electrostatic field. Design and functionality The speakers use a thin flat diaphragm usually consisting of a plastic sheet coated with a conductive material such as graphite sandwiched between two electrically conductive grids, with a small air gap between the diaphragm and grids. For low distortion operation, the diaphragm must operate with a constant charge on its surface, rather than with a constant voltage. This is accomplished by either or both of two techniques: the diaphragm's conductive coating is chosen and applied in a manner to give it a very high surface resistivity, and/or a large value resistor is placed in series between the EHT (Extra High Tension or Voltage) power supply and the diaphragm (resistor not shown in the diagram here). However, the latter technique will still allow distortion as the charge will migrate across the d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loudspeaker
A loudspeaker (commonly referred to as a speaker or speaker driver) is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. A ''speaker system'', also often simply referred to as a "speaker" or "loudspeaker", comprises one or more such speaker ''drivers'', an enclosure, and electrical connections possibly including a crossover network. The speaker driver can be viewed as a linear motor attached to a diaphragm which couples that motor's movement to motion of air, that is, sound. An audio signal, typically from a microphone, recording, or radio broadcast, is amplified electronically to a power level capable of driving that motor in order to reproduce the sound corresponding to the original unamplified electronic signal. This is thus the opposite function to the microphone; indeed the ''dynamic speaker'' driver, by far the most common type, is a linear motor in the same basic configuration as the dynamic microphone which uses such ...

White Bear Lake, Minnesota
White Bear Lake is a city in Ramsey County in the state of Minnesota, United States. A small portion of the city also extends into Washington County. The population was 23,769 at the 2010 census. The city is located on White Bear Lake, one of the largest lakes in the Minneapolis–Saint Paul metropolitan area. Origin of name The city is named after its largest lake, White Bear Lake. American writers have delivered differing versions of the legend that explains the origin of the name. In her book ''Indian Legends of Minnesota'', Mrs. Carl T. Thayer writes that "It is said that a Sioux maiden fell in love with a Chippewa brave. She, the daughter of the Chief, on learning that her father planned war against the Chippewa, ran to her lover and warned him. The brave went alone into the Sioux village to ask for peace and the hand of the maiden. Before the Chief would agree, the Chippewa would have to do a brave deed." "The lovers usually met on Manitou Island. One day, as the bra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quad Electroacoustics
Quad Electroacoustics is a Chinese manufacturer of hi-fi equipment, based in Shenzhen, China. Corporate history The company was founded by Peter J. Walker in 1936 in London, and was initially called ''S.P. Fidelity Sound Systems''. In 1936 the name was changed to the ''Acoustical Manufacturing Co. Ltd''. The company moved from London to Huntingdon in 1941 after being bombed out of London in World War II. The company initially produced only public address equipment but after the war they began to produce equipment designed for use in the home as a result of the rising demand for high quality domestic sound reproduction. Within a few years the company had transitioned almost entirely to manufacturing models for the home audio market. Peter Walker was quoted in December 1975 in ‘Wireless World’ magazine, "An audio power amplifier is required to produce an output signal that differs from the input signal in magnitude only. It must therefore have occurred to every circuit d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manufacturing Companies Based In Minnesota
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 ...
