There is no doubt that bone conduction headsets are a revolutionary product. They are the healthiest headphones, so they are welcomed by many sports fans. Due to the popularity of this kind of headphones, unscrupulous merchants have also begun to target them, launching various low-quality fake bone conduction headsets. They even boasted that this kind of headphone is an upgraded version of bone conduction headsets, and even said that they are the final form of headphones. Many people who do not know much about bone conduction headsets have been fooled because of this, not to mention that they have spent money that they should not have spent, and sometimes bought unhealthy and unsafe products, causing irreparable damage.
So what is the difference between real and fake bone conduction headsets?
Bone conduction headsets are a new type of headphones that use bones to transmit sound. All headphones that do not use bones to transmit sound are fake , even if they look exactly the same. From this perspective, there are at least the following differences between true and fake bone conduction headsets
1) Different sound transmission methods: real bone conduction headsets transmit sound through bones, while fake ones transmit sound through the air;
2) The sound unit is different: the real bone conduction headphone attached to the temple is the bone vibration unit, which is responsible for converting the sound signal into mechanical vibration and transmitting it to the inner ear through the bone; while the fake one is attached to the temple are two speakers. After vocalization, sound waves travel through the air outside the ear and in the ear canal.
3) The airtightness of the body is different: the real bone conduction headsets is an integrated body, and it has no holes, while the fake ones must have holes in the body, otherwise, the sound waves cannot be transmitted.
How do bone conduction headsets work?
Let’s start with a story. Beethoven was a great composer, and he is still loved by many people with representatives such as “Fate Symphony”, “Eroica Symphony “, “Ode of Joy Symphony “ and so on. In fact, Beethoven suffered from hearing impairment in his later years. Even in this state, he continued to compose, which is a bit bizarre. How did he do it? When playing, Beethoven held his baton in his mouth and put the other side on the piano,and then hear the sound.. This was the earliest application case of bone conduction.
In Beethoven’s case, the vibrations caused by the piano as a source of sound are transmitted through the baton to the jawbone on the side of the mouth, and then from the frontal bone to the inner ear, which eventually formed hearing.
You may have found that the entire sound transmission process was the participation of solids such as batons and bones, without the participation of air and the eardrum. This seems to be a little deviated from our daily cognition. If we look through the physics books in middle school, we could know that there are three mediums for sound transmission: namely air, liquid and solid. Human bones are solids, and of course, they can also act as a medium for transmitting sound.
With the above knowledge, it would be easy for us to understand how bone conduction headsets work.
