Talking about the advantages and disadvantages of bone conduction headphones

Bone conduction earphones are also called bone conduction earphones, bone-sensing earphones, bone-sensing earphones, and bone-sensing earphones. It is not a very new concept. After nearly a decade of development, there are now most of them on the market. Most bone conduction headphones still have unsolvable fundamental problems.

The first point is the issue of adaptability. The sounding principle of bone conduction earphones is to rely on its two sounding patches tightly attached to the part of the skull near the ear to conduct the vibration inward to the inner ear lymph fluid, auditory nerve and other structures to produce sound. This clamping is generally It is achieved by the ring-shaped elastic metal in the middle of the two vocal parts. The shape of the skull of different people is different, which leads to the problem that many people cannot achieve the close effect after wearing it, which affects the amount of voice.

The second point is the problem of sound leakage. As mentioned in the previous point, the vibration of the sounding patch will inevitably cause the vibration of the earphone body itself, and drive the vibration of the surrounding air to cause sound leakage. Although this point varies depending on the volume of the headset, it is inevitable in itself unless the shell can be isolated from vibration, which has not yet obtained any principle breakthrough.

The third point is the issue of sound effects. Compared with traditional in-ear headphones, the lack of sound reflection in the ear canal, and keeping the ear canal open will allow various sounds from the environment to enter, resulting in the sound of the earphones being comparable to other types of earphones in terms of size and quality. . Blocking your ears can solve these two problems to a certain extent, but why not just buy an in-ear headset.

Having said that, bone conduction headphones have one and only one advantage: it allows you to receive a sound while keeping the ear canal open. However, it is really useful in many situations, for example:

1. Outdoor sports such as running and mountaineering. Of course, ordinary earphones can also solve the needs of listening to songs (the sound quality is also better), but because of the characteristics of bone conduction earphones, you can also listen to ambient sounds when listening to songs, and you can hear the whistle of bicycles/electric bicycles when running. Safety reminders for passers-by or companions, so that the movement is relatively safer.

2. Driving, this is easy to understand, you can also hear outside sounds such as whistle when making a call, which is naturally safer.
