The first voice synthesizer, Auxetophone, was launched in London in 1898 by Horace Short strong>. The first time, during the Paris festival in 1900, a phonograph playing at the top of the Eiffel Tower was used to spread the operatic space all around.
The sound from the compressed air device could be heard from anywhere in Paris. Short sold the invention’s patent to Charles Parsons in 1903. The first electric powered amplifier was developed in 1906 by Miller Reece Hutchinson and Kelly Turner in New York. It was also a prototype of the most modern systems at the same time. The device, called the Dictograph, was introduced to the market the following year. Electric sound amplifiers were first used in the Olympic Theater in Chicago in September 1912, in cooperation with Bell Telephone Company and Western Electric.
In 1920, inventions emerged that allowed electric sound waves to be recorded and broadcast. In the wake of these inventions, the first speaker was built in 1924-1925. The work done by Chester W. Rice strong> and Edward W. Kellogg strong> developed the speaker.
There are four types of loudspeakers, electrodynamic, magnetostatic, electrostatic and electromagnetic loudspeakers, according to their working modes. Moving coiled speakers come in a diaphragm pitch in the form of a circle or an ellipse. A metal frame hangs around the center of the diaphragm and the springs arranged along its edges. In the middle of the diaphragm is a cylindrical core tightly attached and a voice coil wrapped around it. The coil and the core are placed between the poles of a magnet.
The loudspeaker word in Turkish is French Haut-parleur, which in French means “high-talking / vocal”. Loudspeaker in English and Lautsprecher in German mean the same. The Spanish word for the word Altavoz means “loud.”
