Silicon Valley Iron Man, Space X founder, Tesla founder, PayPal founder, the world's richest man... As the richest man on the planet, Musk has achieved such great success because of his methodology of knowing things. The most famous of these is the "first principle" he has always believed in.
How does Musk see First Principles? He had a saying that goes like this: "It is very important that we think about problems using first principles, rather than thinking in comparison." We always tend to compare in life, and we do everything that others have done or are doing, so that the result of development can only produce small iterative developments. The first-principle way of thinking is to look at the world from the perspective of physics, that is, to peel away the appearance of things layer by layer, to see the essence inside, and then to go up from the essence layer by layer. ”
Principles of sound propagation
Musk's cognition of things can be said to be much higher than ordinary people, if you use the "first principles" he talked about to put into mobile phones, headphones and other technology products, in fact, many things can be explained.
Just like we listen to sound every day, humans invent a variety of headphones, in fact, in order to better receive sound, if a headphone technology has been well developed, and then follow this technology, can only bring about a small iteration. The first principle is to set aside the essence of human listening to sound and iterate from the essence.
The evolution of the rise and evolution of headphone technology
The rise of headphones originated in 1881, but the original headphones had nothing to do with music, and the birth of the world's first pair of headphones was born for communication.
In the next 100 years, the headset has undergone countless iterations and upgrades, and now there are almost only headphones: headphones, dual-line headphones, neck headphones, TWS wireless Bluetooth headphones. But in recent years, there have been new faces in the field of headphones, bone conduction headphones and air conduction headphones.
The origin and evolution of bone conduction headphones
Bone conduction headphones originated in the 18th century, and the principle of bone conduction helped beethoven, a great composer who was deaf in both ears, to hear beautiful music again. Beethoven experimented with a technique invented by Giovanni Filippo Ingracia, who could hear music from his jawbone by biting a stick attached to a piano, which was an early application of the bone conduction principle of sound.
In 2020, Sanag has developed a more suitable air conduction headphone for the general public on the basis of its own bone conduction headphones, comparable to bone conduction, but the price is lower and the comfort is more ergonomic. Its technical principle is evolved and upgraded through bone conduction headphones, and then caused a great response in the market.
Because the bone conduction headphones are transmitted by vibrating the ear bones, long-term wear will make people uncomfortable, and the transformation and upgrading of the air conduction headphones also absorb the characteristics of bone conduction headphones that do not enter the ear and are suitable for sports, reduce sound leakage through directional sound transmission technology, and at the same time will not wear hair tingling and itching for a long time, which not only protects hearing, but also more in line with the hearing experience of normal people.
The rise of this technology also allows the traditional bone conduction headphones to get further iterative upgrades, as people pay more attention to the protection of hearing, more and more people choose to give up in-ear headphones and semi-in-ear headphones, traditional bone conduction headphones due to high prices, long wear hair tingling itching is also more and more rejected, the emerging air conduction headphones due to inexpensive, hearing protection, in line with normal hearing, has become a trend in the development of future headphones.
The first principle of air conduction headphones: receiving sound and protecting hearing
Nowadays, headphones have become a necessity in human life. Whether on the bus, on the subway or on the road, you can see people wearing headphones, headphones have become a plug-in to the human organs, that is, ears, listening to favorite music is a very pleasant thing, does not affect others, immersed in their own world, enjoy their own free time.
And health needs, but also become people's daily life more needed things, many elderly people and children have begun to popularize the air conduction headphones, protection of the ears, not to hurt the hearing is also a major demand. Often wear air conduction headphones for daily movement, not only can listen to external sounds, but also can protect their own safety.
From the perspective of the long history of the development of headphones, the original intention of the technology of air conduction headphones is still to allow humans to receive sound better and more conveniently, and now people's needs are more and more, such as: to protect hearing, convenient movement, etc. It is believed that in the future, there will be more new technologies of headphones, and future headphones will only be more in line with the increasing material and cultural needs of human beings, which is the first principle advocated by Musk.
