Electrophons: features, principle of operation, use

Musical systems were popular and in demand at all times. So, for high-quality playback of gramzapsy, such a device was developed as an electrophon. It consisted of 3 main blocks and most often was made of available details. In the times of the Soviet Union, this device used rabid popularity.

In this article we will get closer to the features of the electrophones and find out what the principle of their work is.

What is an electric phone?

Before deeply delve into the features of the device of this interesting technical device, it should be understood that it represents. So, the electrophon (abbreviated name from the “electropathyphone”) is an equipment designed to reproduce sound from once common vinyl records.

In everyday life, this device was often called simply – “Player”.

Such an interesting and in demand during the Soviet Union technique could reproduce mono-, stereo sounds and even quadrophonic audio recordings. This device was distinguished by high playback quality than attracted many consumers.

Since this device was invented, it was not modified and complemented by useful configurations.

History of creation

And electric foams and electric players are required by their appearance on the market one of the first sound cinema systems called “Waitafon”. The phonogram of the film was played directly from the grammplastine using the flash drive, the rotating drive of which was synchronized with the shaft of the projector film broach. Fresh at that time and advanced technology of electromechanical sound playback gave the audience excellent sound. The sound quality was higher than in the case of simple “gramophone” stations of film refinement (such as chronicphone “Gomon”).

The first model of the flash drive was developed in the USSR in the distant 1932. Then this device received the name – “Erg” (“Electroeradiogramphone”). Then it was assumed that the Moscow Electrotechnical Plant “Moselectric” will be supposed to produce such devices, but the plans were not implemented, and this did not happen. The Soviet industry in the period before the war has been manufactured more than standard plates of gramophone plates in which additional power amplifiers were not provided.

The first electrophone of widespread production was released only in 1953. He was called “UP-2” (deciphered as “universal player”). Provided this model Vilnius Plant “Elf”. The new apparatus was assembled on 3 radiologists.

He could play not only standard plates at a speed of 78 rpm, but also long-playing varieties of plates at a speed of 33 rpm.

In the electrophone “UP-2” there were replaced needles that were made from high-quality and wear-resistant steel.

In 1957, they released the first Soviet electrophone, which could be used to play surround sound. This model “Jubilee-stereo”. It was the highest quality apparatus, in which 3 rotation speeds were provided, a built-in amplifier on 7 lamps and 2 acoustic external acoustic systems.

In total, about 40 models of flaps were made in the USSR. Over the years, certain copies have been equipped with imported details. Development and improvement of such equipment were suspended with the collapse of the USSR. True, small parties of spare parts continued to be issued until 1994. Operation of grammptine as sound carriers decreased sharply in the 90s. Many flashlights were simply thrown out, since they became no one needed.

Device

The main component of the electrophones is an electro player (or eppa). It is implemented in the form of a functional and completed block.

In the configuration of this important component are present:

  • Electric engine;
  • Massive disk;
  • Tonarm with an amplifier head;
  • A variety of auxiliary parts, such as a special groove for a plate, microlift used for neat and smooth down or lifting the pickup head.

Electrophone can be represented as an eppa, placed in a housing base with a power supply, spare parts, amplifier and acoustics system.

Principle of operation

The scheme of the work of the device under consideration can not be called too complicated. It is only necessary to take into account the fact that such a technique differs from others like it, which was produced earlier.

Electrophone should not be confused with conventional gramophone or gramophone. It differs from these devices by the fact that in it the mechanical oscillations of the needle of the pickup are converted into electrochails passing through a special amplifier.

After that, there is a direct conversion into sound with the help of an electro-acoustic system. The latter includes from 1 to 4 electrodynamic loudspeakers. Their number depended only on the characteristics of a particular device model.

Electrophons are with a belt or direct drive. In the latest options, the transmission of the moment of rotation from the electric motor comes directly to the apparatus shaft.

The transmission of electrically playing units involving a lot of speeds may contain a gear rating mechanism using a stepped type shaft belonging to the engine and an intermediate rubberized wheel. Standard plate speed indicator was 33 and 1/3 rpm.

To make compatibility with old gramophone plates, in many models it was possible to independently adjust the speed of rotation from 45 to 78 rpm.

For what is used?

In the West, namely in the territory of the United States, the electricifones were published even before the beginning of World War II. But in the USSR, as described above, their production was put on the flow later – only in the 1950s. To this day, these devices are applied to everyday life, as well as in electronic music in combination with other functional instruments.

At home, the electrophones are practically not used today. Vinyl plates also ceased to use their own popularity, because more functional and modern devices came to the place of these things, to which other equipment, such as headphones, flash cards, smartphones can be connected.

Electrophone at home recently meet very hard.

As a rule, this machine prefers to establish people who have analog sound. It seems more “alive”, saturated, juicy and pleasant to perception.

Of course, these are only subjective sensations of certain individuals. It is impossible listed epithets to attribute to the exact characteristics of the considered aggregates.

Best models

We will get acquainted closer with some of the most popular electrophons models.

  • Electronics toy “Electronics”. The model was produced by the Pskov factory of radio components since 1975. The device could play plates, the diameter of which did not exceed 25 cm markers at a speed of 33 rpm. Until 1982, the electric hamme rate of this popular model was collected on special Germany transistors, but over time it was decided to switch to silicon options and chips.

  • QuadroFonic apparatus “Phoenix-002-quadro”. The model was produced by a Lviv plant. “Phoenix” was the first Soviet quadraphonic apparatus of the highest class.

Aligned with high-quality playback and equipped with a 4-channel pre-amplifier.

  • Lamp apparatus “Volga”. Released since 1957, had compact dimensions. This is a lamp unit, which has been manufactured in an oval cardboard box, an estimated dermatin and a panel. In the device, an improved electrical engine was provided. Weight apparatus 6 kg.

  • Stereo Radiogramphone “Jubilee RG-4C”. The device was made by Leningrad Council. The beginning of the release dates back to 1959.

  • Upgraded, but reduced model, following which the plant began to produce and produce Apparatus with the index “RG-5C”. The model “RG-4C” became the first stereo device with the presence of a two-channel high-quality amplifier. There was a special pick-up, which could smoothly interact with classic plates, and with their long-playing varieties.
