Headphones 1924 came out, which was invented by German You Ergen Bayer. Jurgenbair opened an electronics subsidiary in Berlin, specializing in the research and development of electric transducers, mainly studying loudspeakers and applying such loudspeakers to other similar devices. Young Bell has always had a dream, that is, how to transmit music directly to people's ears and reduce the influence of air. At first, the loudspeaker was very big. Later, he began to study and reduced the size of the loudspeaker again and again. Finally, he developed an arc-shaped fixing device similar to an ear. He developed a small speaker and fixed it on an arc-shaped shelf, so the world's first earphone was born.
Bayer once invited his friends to Berlin's fever room to listen to the opera. When his friend came here, he saw the record player, but there was no sign of a loudspeaker or loudspeaker. There is a metal arc monster lying quietly next to the record player, with an earmuff at each end. Everyone knew it was an earphone, but it was a miracle for people at that time. He could also sing. On this historic day, DT48 headphones were born. The frequency response and analysis of DT48 headphones were used by German intelligence department and Gestapo to detect the sound that other headphones could not distinguish, and a lot of valuable information was obtained. 1950, the world's first stereo headset went on the market, which once again caused a sensation in the world. DT48 series headphones have been sold for the longest time in the world.
The application of headphones in our life today, today's earphone forms have a variety of styles, and earphone manufacturers will also pay attention to the appearance of their headphones. There are more and more headphones with fashionable styles and excellent sound quality.
