Before the second industrial revolution, there was no electricity, and certainly no headphones. But those who had the opportunity to appreciate music at that time were also very happy, because all were original sounds and there was no electronic noise. After the power was turned on, the invention of the electric appliance began to expand rapidly. Edison invented the phonograph and benefited thousands of friends who love music and sound art. It opened the era of music recording. It is a combination of a player, an amplifier and a sound reinforcement horn.

After World War II, with the application of new technologies, some decomposition products, such as audio sources, players, converters, amplifiers, speakers, headphones, etc., have emerged. Music storage media has also evolved from early film discs to tape reels, CDs, and more. Early headphones were designed for use in desktop playback equipment. Beginning in the 1970s and 1980s, a large number of portable players, such as portable tape drives and portable CD players, were collectively called Walkman. The production of portable headsets has also prospered.
The development of headphones has indeed brought a lot of fun to our lives. While enjoying the wonderful music and the development of headphones has indeed brought a lot of fun to our lives, do we think of the pioneers of headphones products?
Baia and his friends
Mr. Eugen Beyer founded an electronics company in Berlin in 1924, when the company developed and manufactured loudspeakers for cinemas and began its legend in the audio field.
On August 18, 1937, Eugen Beyer applied the dynamic transducer used on the theater speaker to a similar product. He transmitted the sound directly to the human auditory organ, the ear, and invented a A miniature moving coil transducer was placed in a strap that could be worn on the head, which gave birth to the world's first earphone.

On this historic day, people witnessed the birth of the Beyerdynamic DT48 headset and created a world record that made a splash around the world!
The world's first headset
After the first earphone was born, Mr. Beyer invited a group of friends to his private "studio" and played the record of the classic repertoire "Aida". The friends found that the phonograph didn't have the speakers as usual, but an external amplifier and two unobtrusive semi-circular metal earmuffs. What's even more amazing is that the sound from the earmuffs is very good. There is no telephone murmur, no low-pitched drum sound or squeaky string sound. Mr. Beyer is playing real music!
This is the most exciting performance of "Aida" since the invention of the recording equipment. It was realized in the "studio" of Mr. Beyer with the first dynamic earphone he invented. "Friends," Mr. Beyer said to the stunned listeners, "This is my hard work, and humans can enjoy the original music outside the concert hall."

Speaking of DT48, there is still a short story. In the 1930s, the German intelligence department and the Gestapo used this earphone to detect sounds that other headphones could not discern, and obtained a lot of valuable information. The DT48's frequency response ranged from 16 to 20 kHz, an unimaginable indicator of technology in the 1930s. The headset was called the Berlin brand. In 1950, Beyerdynamic launched the world's first stereo headset - DT48S, once again sensational world, leading the pack.
What's more interesting is that, more than 60 years later, Beyerdynamic still produces DT48 series headphones, but only uses more advanced materials. This is the longest headset in the world. Its milestone contribution to professional radio, recording and video studios has gone down in history.
The earliest open earphone products are all placed in the auricle. They are neither soundproof nor severely leaking when listening. However, due to the limitations of technology at the time, the earphones still exist for a long time. time. Later, various types of earphone styles and technologies such as open, semi-open, closed (closed) appeared. Headphone manufacturers such as Beyerdynamic, Sennheiser, and Iron Triangle have made tremendous contributions.
Some people say that the headset is a smaller version of the speaker, indeed, the two have many similarities in structure. This is of course the two are originally homologous, and the electro-acoustic simulation technology has developed to the present, has encountered the theoretical bottleneck, and now only compensated from ergonomics, industrial design and materials science.
[page]Modern people are not only pursuing sound quality, but also pursuing the power of headphones. And the development of headphones has a history of not too young, what is the trend of headphones in the future? Xiaobian summed up a few points to smash netizens.
First, wireless headphones are becoming more and more popularWireless headsets get rid of the shackles of cumbersome wires, you can listen to songs with headphones and watch movies on a business trip, the activity is very free. This year, major manufacturers have launched their own wireless headsets. What is the biggest reason to block the popularity of wireless headphones? Among the many optional conditions, most netizens believe that the problem of sound quality and delay has caused the wireless headphones to be neither hot nor cold, but the price. In fact, the sound quality and delay problems have been greatly improved in the current mature solutions, the only thing that can prevent its popularity is the price. Wireless headsets are much more expensive than regular wired headsets, "scare" a lot of consumers. Looking at the entire wireless headset market, the outlook is very optimistic, but there are still many technical obstacles to break through.

The development of HiFi concept to high-end HIFI is deeply rooted in the hearts of the people. At present, high-end HiFi earphones are high and low. For manufacturers, in fact, they are more willing to give birth to some "going" products, which will not only expand the influence of the brand, but also compare Objective economic benefits. But with the development of technology, the cost of high-quality headphones will decrease. There will be more and more high quality and low price headphones.

The headset is personalized and fashionable. Some fashion-oriented earphone products for young users have done a good job in appearance. The earphones are not only a tool for sound reproduction and restoration. Nowadays, headphones are a symbol of fashion and a symbol of personality.

The outbreak of Apple's earphones is an example. The popularity of Apple's earphones is said: Apple apple manufacturers who sell apples are not as good as Apple apples (referring to Apple accessories).
Fourth, the headset intelligent function diversificationHeadphones can now be equipped with more and more functions. There are Bluetooth direct reading SD card U disk with MP3 function battery FM radio, microphone touch waterproof can be used for TV, change the voice as long as you can think of it can give you integration Eat all but have to have a main selling point.
Headphones show a more and more distinct tendency to "integrate into the playback device". At present, many earphones in the industry already have digital terminal elements, and functional design is increasingly considering the actual use of users.
By merging the source with the headphones, you only need one headset to complete the entire music playback process. Among them, the earphone, the sound source, the battery, the control button and the like are omitted, and the steps of connecting and carrying the sound source are omitted, which greatly simplifies the user's listening process.
It is foreseeable in the future that headphones will become part of people's lives. Now is the age of personality, everyone's taste is different, everyone wants to have their own music space, headphones can achieve this. If a set of audio is to be effective, the requirements for the house are high, and the cost of the audio equipment is avoided. The cost of decorating the house is also amazing. Compared with audio equipment, the whole headset system costs much less and is more acceptable. Headphones, the future development direction, earphone enthusiasts are also constantly increasing, the pursuit of quality will make people invest more and more in headphones.
