Horn Loudspeaker
A horn loudspeaker is a loudspeaker or loudspeaker element which uses an horn (acoustic), acoustic horn to increase the overall efficiency of the driving element(s). A common form ''(right)'' consists of a compression driver which produces sound waves with a small metal diaphragm vibrated by an electromagnet, attached to a horn, a flaring duct to conduct the sound waves to the open air. Another type is a woofer driver mounted in a loudspeaker enclosure which is divided by internal partitions to form a zigzag flaring duct which functions as a horn; this type is called a ''folded horn'' speaker. The horn serves to improve the coupling efficiency between the speaker driver and the air. The horn can be thought of as an "acoustic transformer" that provides impedance matching between the relatively density, dense diaphragm material and the less-dense air. The result is greater acoustic output power from a given driver. The narrow part of the horn next to the driver is called the "throat" ...

John Kenneth Hilliard
John Kenneth Hilliard (October 1901 – March 21, 1989) was an American acoustical and electrical engineer who pioneered a number of important loudspeaker concepts and designs. He helped develop the practical use of recording sound for film, and won an Academy Award in 1935. He designed movie theater sound systems, and he worked on radar as well as submarine detection equipment during World War II. Hilliard collaborated with James B. "Jim" Lansing in creating the long-lived Altec Voice of the Theatre speaker system. Hilliard researched high-intensity acoustics, vibration, miniaturization and long-line communications for NASA and the Air Force. Near the end of his career, he standardized noise-control criteria for home construction in California, a pattern since applied to new homes throughout the U.S. Education Born in October 1901 in Wyndmere, North Dakota, Hilliard received his B.S. degree from Hamline University in St. Paul, Minnesota at 24 years of age. He then obtained a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electronics Companies Established In 1979
The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as 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 society. The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small electr ...

QSC Audio Products
QSC is an American manufacturer of audio products including power amplifiers, loudspeakers, digital mixers and digital signal processors including the Q-Sys networked audio, video and control platform. QSC products are used by professional installed, portable, production, corporate and cinema customers worldwide. History The company was founded in 1968 by Patrick Howe Quilter, who serves as chairman of the board of directors. Quilter was at the time an engineering student with a keen interest in electronics and music. In 1967 Quilter had learned that the bass player in his brother’s high school band was searching for an affordable bass amp. When Quilter learned his budget was $250.00, he said “I could probably make you something for that kind of money,” giving birth to the first QSC amp. With many musician friends and acquaintances seeking him out to make guitar amps, he left school to start his company with the financial backing of family and friends. At first the compan ...

Loudspeaker Enclosure
A loudspeaker enclosure or loudspeaker cabinet is an enclosure (often rectangular box-shaped) in which speaker drivers (e.g., loudspeakers and tweeters) and associated electronic hardware, such as crossover circuits and, in some cases, power amplifiers, are mounted. Enclosures may range in design from simple, homemade DIY rectangular particleboard boxes to very complex, expensive computer-designed hi-fi cabinets that incorporate composite materials, internal baffles, horns, bass reflex ports and acoustic insulation. Loudspeaker enclosures range in size from small "bookshelf" speaker cabinets with woofers and small tweeters designed for listening to music with a hi-fi system in a private home to huge, heavy subwoofer enclosures with multiple or even speakers in huge enclosures which are designed for use in stadium concert sound reinforcement systems for rock music concerts. The primary role of the enclosure is to prevent sound waves generated by the rearward-facing surfa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Research And Development
Research and development (R&D or R+D), known in Europe as research and technological development (RTD), is the set of innovative activities undertaken by corporations or governments in developing new services or products, and improving existing ones. Research and development constitutes the first stage of development of a potential new service or the production process. R&D activities differ from institution to institution, with two primary models of an R&D department either staffed by engineers and tasked with directly developing new products, or staffed with industrial scientists and tasked with applied research in scientific or technological fields, which may facilitate future product development. R&D differs from the vast majority of corporate activities in that it is not intended to yield immediate profit, and generally carries greater risk and an uncertain return on investment. However R&D is crucial for acquiring larger shares of the market through the marketisation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
