Subsidiary
A subsidiary, subsidiary company, or daughter company is a company (law), company completely or partially owned or controlled by another company, called the parent company or holding company, which has legal and financial control over the subsidiary company. Unlike regional branches or divisions, subsidiaries are considered to be distinct entities from their parent companies; they are required to follow the laws of where they are incorporated, and they maintain their own executive leadership. Two or more subsidiaries primarily controlled by same entity/group are considered to be sister companies of each other. Subsidiaries are a common feature of modern business, and most multinational corporations organize their operations via the creation and purchase of subsidiary companies. Examples of holding companies are Berkshire Hathaway, Jefferies Financial Group, The Walt Disney Company, Warner Bros. Discovery, and Citigroup, which have subsidiaries involved in many different Industry (e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loudspeaker
A loudspeaker (commonly referred to as a speaker or, more fully, a speaker system) is a combination of one or more speaker drivers, an enclosure, and electrical connections (possibly including a crossover network). The speaker driver is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. The driver is a linear motor connected to a diaphragm, which transmits the motor's movement to produce sound by moving air. An audio signal, typically originating from a microphone, recording, or radio broadcast, is electronically amplified to a power level sufficient to drive the motor, reproducing the sound corresponding to the original unamplified signal. This process functions as the inverse of a microphone. In fact, the ''dynamic speaker'' driver—the most common type—shares the same basic configuration as a dynamic microphone, which operates in reverse as a generator. The dynamic speaker was invented in 1925 by Edward W. Kellogg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grammy Award
The Grammy Awards, stylized as GRAMMY, and often referred to as The Grammys, are awards presented by The Recording Academy of the United States to recognize outstanding achievements in music. They are regarded by many as the most prestigious and significant awards in the music industry in the United States, and thus the show is frequently called "music's biggest night". The trophy depicts a gilded gramophone, and the original idea was to call them the "Gramophone Awards". The Grammys are the first of the Big Three networks' major music awards held annually, and are considered one of the four major annual American entertainment awards with the Academy Awards (for films), the Emmy Awards (for television), and the Tony Awards (for theater). The first Grammy Awards ceremony was held on May 4, 1959, to honor the musical accomplishments of performers for the year 1958. After the 2011 ceremony, the Recording Academy overhauled many Grammy Award categories for 2012. The 67th Ann ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microphone Pick Up Patterns
A microphone, colloquially called a mic (), or mike, is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, and radio and television broadcasting. They are also used in computers and other electronic devices, such as mobile phones, for recording sounds, speech recognition, VoIP, and other purposes, such as ultrasonic sensors or knock sensors. Several types of microphone are used today, which employ different methods to convert the air pressure variations of a sound wave to an electrical signal. The most common are the dynamic microphone, which uses a coil of wire suspended in a magnetic field; the condenser microphone, which uses the vibrating diaphragm as a capacitor plate; and the contact microphone, which uses a crystal of ...

Headphones
Headphones are a pair of small loudspeaker drivers worn on or around the head over a user's ears. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound. Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby to hear. Headphones are also known as earphones or, colloquially, cans. Circumaural (around the ear) and supra-aural (over the ear) headphones use a band over the top of the head to hold the drivers in place. Another type, known as earbuds or earpieces, consists of individual units that plug into the user's ear canal; within that category have been developed cordless air buds using wireless technology. A third type are bone conduction headphones, which typically wrap around the back of the head and rest in front of the ear canal, leaving the ear canal open. In the context of telecommunication, a headset is a combination of a hea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blue Chip (stock Market)
A blue chip is capital stock of a Corporation, stock corporation with a national reputation for quality, reliability, and the ability to operate profitably in both good and bad times. Origin As befits the sometimes high-risk nature of stock picking, the term "blue chip" derives from the card game poker. The simplest sets of casino token, poker chips include casino token#Colors, white, red, and blue chips, with American tradition dictating that the blues are highest in value. In the United States, blue chips were traditionally used for higher values such that "blue chip" used in noun and adjectival word sense, senses are attested since 1873 and 1894, respectively. This established connotation was first extended to the sense of a blue-chip stock in the 1920s. According to Dow Jones & Company, Dow Jones company folklore, this sense extension was coined by Oliver Gingold (an early employee of the company that would become Dow Jones) sometime in the 1920s, when Gingold was standing ...

Magnetic Cartridge
A magnetic cartridge, more commonly called a phonograph cartridge or phono cartridge or (colloquially) a pickup, is an electromechanical transducer that is used to play phonograph records on a Phonograph, turntable. The cartridge contains a removable or permanently mounted phonograph#Stylus, stylus, the tip - usually a gemstone, such as diamond or sapphire - of which makes physical contact with the record's groove. In popular usage and in disc jockey jargon, the stylus, and sometimes the entire cartridge, is often called the needle. As the stylus tracks the serrated groove, it vibrates a cantilever on which is mounted a permanent magnet which moves between the magnetic fields of sets of electromagnetic coils in the cartridge (or vice versa: the coils are mounted on the cantilever, and the magnets are in the cartridge). The shifting magnetic fields generate an electrical current in the coils. The electrical signal generated by the cartridge can be amplifier, amplified and then c ...
