Home Audio
Home audio refer to audio consumer electronics designed for home entertainment, such as integrated systems like shelf stereos, as well as individual components like loudspeakers and surround sound receivers. The evolution of home audio began with Edison's phonograph, transitioning from monaural to stereophonic sound in the 1950s and 60s when the term "hi-fi" emerged, highlighting sound accuracy and minimal distortion. Audio equipment evolved from large wooden cabinets to compact units. The 1970s introduced enhancements like quadraphonic sound and technologies like Dolby Pro Logic. This era also saw the rise of component-based stereo systems, and cassette decks too became a staple. Integrated systems, termed "music centers" gained popularity in the 1980s. Table systems and compact radio receivers emerged as entertainment devices, with some offering features like cassette players and CD functionalities. Audiophile systems prioritize high-quality music formats and specialized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zenith Phonograph (radiogram)%2C Around 1960
The zenith (, ) is the imaginary point on the celestial sphere directly "above" a particular location. "Above" means in the vertical direction (plumb line) opposite to the gravity direction at that location (nadir). The zenith is the "highest" point on the celestial sphere. The direction opposite of the zenith is the nadir. Origin The word ''zenith'' derives from an inaccurate reading of the Arabic expression (), meaning "direction of the head" or "path above the head", by Medieval Latin scribes in the Middle Ages (during the 14th century), possibly through Old Spanish. It was reduced to ''samt'' ("direction") and miswritten as ''senit''/''cenit'', the ''m'' being misread as ''ni''. Through the Old French ''cenith'', ''zenith'' first appeared in the 17th century.

Radiogram (device)
In British English, a radiogram is a piece of furniture that combined a Receiver (radio), radio and Phonograph, record player. The word ''radiogram'' is a portmanteau of ''Radio receiver, radio'' and ''phonograph, gramophone''. The corresponding term in American English is Entertainment center, console. Popularity Radiograms reached their peak of popularity in the post-war era, supported by a rapidly growing interest in Gramophone record, records. Originally they were made of Wood finishing, polished wood to blend with the furniture of the 1930s, with many styled by the leading designers of the day. An expensive instrument of entertainment for the house, fitted with a larger loudspeaker than the domestic radio, the radiogram soon began to develop features such as the record autochanger, which would accept six or seven records and play them one after another. Certain recordings could be ordered as a box set which would combine the recorded piece in order, to suit an autochanger set ...

Record Player
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 Waveform, 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 ''Phonograph record, record''. To recreate the sound, the surface is similarly rotated while a playback #Stylus, stylus traces the groove and is therefore vibrated by it, faintly reproducing the recorded sound. In early acoustic phonographs, the stylus vibrated a Diaphragm (acoustics), diaphragm that produced sound waves coupled to the open air through a flaring Horn loudspeaker, 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 an ...

Radio Receiver
In radio communications, a radio receiver, also known as a receiver, a wireless, or simply a radio, is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna. The antenna intercepts radio waves (electromagnetic waves of radio frequency) and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information. The receiver uses electronic filters to separate the desired radio frequency signal from all the other signals picked up by the antenna, an electronic amplifier to increase the power of the signal for further processing, and finally recovers the desired information through demodulation. Radio receivers are essential components of all systems based on radio technology. The information produced by the receiver may be in the form of sound, video (television), or digital data. A radio receiver may be a separate piece of electronic equ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
