Who invented the tape recorder? Who invented the tape recorder in what year

In 1898, the Danish scientist Paussen developed the first magnetic tape recorder based on Smith's theory.

In 1900, the Paris Exposition exhibited the magnetic tape recorder invented by Pausson. Since this type of tape recorder records sound on a tightrope, it has unique advantages compared to gramophones. At the fair, it was favored by the people.

However, magnetic recordings require very high quality steel wires and steel tapes, and are very bulky and inconvenient to use. So, in 1930, Freuima in Germany proposed a new scheme, that is, to replace steel wire or steel with paper or plastic tape coated with iron powder. After six years of hard work, in 1936 Frauima developed the tape recorder.

Compared with magnetic voice recorders, this kind of recorder has clear sound, easy to use, and is cheaper.

Marvin made a wire recorder with a new principle in 1937. It uses a complete magnetic coil as the head, and the steel wire passes through the coil and is spaced apart from the magnetic coil, so that the air space around the steel wire can be used for recording. Because this layer of air gap encloses the surface layer of the wire, it is homogeneous.

The performance of this recorder is much better than that of previous recorders. It has a realistic sound and beautiful sound quality. Marvin's cousin was singing indulgently, and then it was played by this tape recorder, and people joked:

The singing level of this 'amateur singer' has improved many times in an instant. ”

After that, Marvin made improvements to this tape recorder and made it into a lightweight, thin plastic tape. Since then, he has also invented the "high-fidelity multi-channel stereo" playback device.

Inventors of the tape recorder: Marvin Kamras (USA), Friomer (Germany) (1935).

Mr. Edison:

When he was only twenty-three years old, Dickson made his first invention, the electronic vote recorder, which was not marketable, and Edison concentrated on inventing what he expected to be easy to market. Shortly after the invention of the recorder, Edison invented an improved **** automatic recorder in exchange for forty thousand dollars, which was a huge income at the time. Edison went on to make a series of other inventions, and soon became famous and rich.

Perhaps his most inventive invention was the phonograph, which he patented in 1877. But what was more important to the world was that in 1879 he invented a practical incandescent light bulb.

v.Poulson invented the wire tape recorder.

In 1907, Poulson invented the DC bias method of the wire tape recorder, which made the tape recorder enter the practical stage of Pei Qiliang.

In 1927, Carson and Coppen invented the steel wire recorder mating wide-current bias method (the alternating current bias method used was developed by later generations).

In 1930, a steel wire tape recorder appeared, and soon a steel tape recorder appeared.

In 1935, the German company General Electric made a tape recorder.

In 1907, Poulson invented the DC bias and wide magnetic method of the wire tape recorder, which brought the tape recorder into the practical stage.

<> counter in the old Yuming Cave Hidden Tape Recorder was invented by Arnold Fleming. Fleming invented the first tape recorder counter in 1948 and used it on one of Alpine's tape recorders. At that time, the Celestial Warning Counter was mainly used to track the length of the tape in order to create a tape with the exact length.

Tape recorder, a kind of machine capable of recording sound and reproducing sound, it uses hard magnetic material as the carrier, and uses the remanence characteristics of magnetic material to record the sound signal in the carrier, and generally has the function of replaying.
