Innovations in consumer electronicsEdit
1843-1923: From electromechanics to electronicsEdit
- 1843: Watchmaker Alexander Bain (inventor) develops the basic concept of displaying images as points with different brightness values.
- 1848: Frederick Collier Bakewell invents the first wirephoto machine, an early fax machine
- 1861: Grade school teacher Philipp Reis presents his telephone in Frankfurt, inventing the loudspeaker as a by-product.
- 1867: French poet and philosopher Charles Cros (1842 - 1888) presents the construction principle of a phonograph in his 'paréophone', which turned out not to be a commercial success at the time.
- 1867: James Clerk Maxwell (1831 - 1879) develops a theory predicting the existence of electromagnetic waves and establishes Maxwell's equations to describe their properties. Together with the Lorentz force law, these equations form the foundation for classical electrodynamics and classical optics as well as electric circuits.
- 1874: Ferdinand Braun discovers the rectifier effect in metal sulfides and metal oxides.
- 1877: Thomas Edison (1847 - 1931) invents the first phonograph, using a tin foil cylinder. For the first time sounds could be recorded and played. A phonograph horn with membrane and needle was arranged in such a way that the needle had contact to the tinfoil.
- 1880: the American physicist Charles Sumner Tainter discovers that many disadvantages of Edison's cylinders can be eliminated if the soundtrack is arranged in spiral form and engraved in a flat, round disk. Technical problems soon ended these experiments. Still, Tainter is regarded as the inventor of the gramophone record.
- 1884: Paul Nipkow obtains a patent for his Nipkow disk, an image scanning device that reads images serially, which constitutes the foundation for mechanical television. Two years later his patent runs out.
- 1886: Heinrich Hertz succeeds in proving the existence of electromagnetic waves for the first time - now the groundwork for wireless telegraphy and radio broadcasting in physical science is laid.
- 1887: Unaware of Charles Sumner Tainter's experiments, German-American Emil Berliner has his phonograph patented. He used a disk instead of a cylinder, primarily to avoid infringing on Edison's patent. Quickly it becomes obvious that flat Gramophone records are easier to duplicate and store.
- Alexander Graham Bell (1847 - 1922) significantly reduces interfering noises by using a wax cylinder instead of tin foil. This paves the way to commercial success for the improved phonograph.
- American Oberlin Smith describes a process to record audio using a cotton thread with integrated fine wire clippings. This makes reel-to-reel audio tape recording possible.
- The phonograph becomes faster and more convenient due to an electric motor. The electric motor brings on the first juke box with cylinders - even before flat disk records were widely available.
- Thomas Edison discovers thermionic emission. To this day, this effect forms the basis for the vacuum tube and the cathode ray tube.
- approximately 1893: The invention of the selenium phototube allows the conversion of brightness values into electrical signals. The principle is applied in wirephoto and television technology for a short time. Selenium is used in light meters for the next 50 years.
- 1895: Auguste Lumiere's cinematograph displays moving images for the first time. In the same year, brothers Emil and Max Skladanowsky present their "Bioscop" in Berlin.
- 1899: The dog "Nipper" is used in "His Master's Voice", the trademark for gramophones and records.
- Otto von Bronk patented his "Method and apparatus for remote visualization of images and objects with temporary resolution of the images in parallel rows of dots". This patent, originally developed for phototelegraphy, impacted the development of color television, particularly the NTSC implementation.
- For the first time audio records are printed with paper labels in the middle.
- 1903: Guglielmo Marconi provides evidence that wireless telegraphic communication is possible over long distances, such as across the Atlantic. He used a transmitter developed by Ferdinand Braun.
- For the first time, double-sided records, and those with a diameter of 30 cm are produced, increasing playing time up to 11 minutes (5.5 minutes per side). These are created by Odeon in Berlin and debuted at the Leipzig Spring Fair.
- The German physicist Arthur Korn developed the first practical method for telegraphy.
- 1905: The Englishman Sir John Ambrose Fleming invents the first electron tube.
