Welcome to our new site! On this website we will try to reach turntable and record player enthusiasts, as well as some other lovers of the good sound.
So, lets begin with a brief turntable history:
Year 1877 went down in history as the year when for the first time sound is recorded and reproduced. Thomas Edison and his assistant John Kruesi excitedly listened to the squeaky sound that was coming from the rotating cylinder phonograph. Just a minute or two before, Edison is in a metal tube of his voice machines recited:
Mary had a little lamb. Its flees was white as snow …
These were the first words that were written on a sound carrier and later successfully reproduced. The great inventor and his assistant were delighted with the result.
It all started back in 1850.g. when French researchers have developed phonoautograph, a machine that is able to record sound on a rotating cylinder. Something about a quality of a soundtrack produced with phonautograph is impossible to say because its designers did not foresee the possibility of playing back a sound track? !! Twenty years later, Thomas Edison started the development of voice machines using technical solutions to French researchers. Very quickly, Edison and his assistant, made the first drawings to which they built their first voice machine – the phonograph.
The basis of the phonograph was a rotating cylinder spiral frayed and covered with a very thin lead foil. After the film is slid iron needle attached to the diaphragm, which was located at the bottom of a metal tube in which it was spoken. When, therefore, in the vicinity of the diaphragm producing sound (must have been a pretty powerful sound) diaphragm is oscillated, and this oscillation is transmitted to the needle which is flatten lead foil in the groove of the cylinder in accordance with the intensity of the sound.
In a similar manner sound was reproduced. The change in the depth of embossed foil drove the needle that oscillates up and down. This oscillation is transmitted to the diaphragm that produced sound.
In later models, better quality soundtrack received with cylinders coated with wax instead of lead foil. Rollers coated with wax had the possibility to give the data for two to four minutes of audio signals.
Following significant progress occurred in 1887 when Emile Berliner introduced vinyl records instead of the roller and a new way to record sound.
Instead of vertical vibration of the needle which caused the variations in the depth of embossed upholstery roller, with vinyl records sound was causing the oscillation of the needle from side to side. It has been shown that this technique record and playback sound much better. Yes it was very technical and a measurable improvement shown by the fact that this type of audio on vinyl records remained in use until the vinyl records are not ten years ago replaced with a compact discs.
It is important to note that the sound reproduction Berliner gramophone still based on the mechanical transmission of vibrations. The oscillating needle is mechanically connected to the diaphragm, which is using a large horn that produced sound.
The emergence of the first device that is magnetically recorded sound took place in 1898 thanks to patent the Danish inventor Valdemar Poulsen. But soon after the improved properties of vacuum tubes in the early 20th century, enabled the conversion of sound into electrical impulses, and the very conversion of these signals. Already in 1928 he developed the first magnetic tape and in Germany, where the 30’s and 40’s of the 20th century, successive improvements to the appearance of the first devices to record tapes (Magnetophone). After II. World War II technology was transferred to the United States and already in 1946 began the mass production of tape.
1960s brought a new wave in the development of sound reproduction because of the start of FM stereo transmission. The development of triple and quadruple tape recorder and development of a “one-inch” tape recording soon followed. It is these new technologies have contributed to the development of the music industry of in all aspects.
The development of digital records began in the early 1970s, but it was only in 1978 Sony Corporation demonstrated the use of a video recorder for recording digital data, sound and images. That same year the developed digital systems for editing. Sony and Philips Electronics NV have agreed to 1981 about “compact disc” (CD) format, and in 1983 it introduced the first CD playback device. Since that day, this technology is advanced. Apart from the larger media capacity, faster playback device, and new formats, digital music, there has not been some breakthroughs in the field of sound recording.
