What is the principle of bone conduction?
If you want to know the working principle of bone conduction headphones, you must first know that under normal circumstances, whether it is ordinary wired headphones, Bluetooth headphones or noise reduction headphones, they are essentially "air conduction headphones", that is, the air in the external auditory canal is the main sound transmission medium, and only a small part of sound waves propagate through bones. The most unique feature of bone conduction headphones is that sound waves do not pass through the air in the external auditory canal and tympanic membrane, but directly use the human bone structure as the sound transmission medium.

Bone conduction headphones vibrate through the cavity, sound waves pass through the skull, bypass the external auditory canal and tympanic membrane, and then listen to the ossicles to introduce sound waves into the bone labyrinth, so that sound information can be transmitted to the cochlea and auditory nerve. In this way, we can successfully use bone conduction technology to hear the sound, which is the working principle of bone conduction headphones.

Knowing the working principle of bone conduction headphones, what are the benefits of bone conduction headphones? Let me analyze them one by one.

1. Wear healthier clothes.

Bone conduction headphones are worn in a different way from ordinary headphones and do not need to be worn in the ear. Reduced the damage of 100% to the external auditory canal. It also avoids that the ear is not ventilated because the earphone blocks the ear canal, and it also avoids the breeding of a large number of bacteria because the ear is not ventilated. In this way, ear diseases caused by headphones will not occur, which is the healthiest way to wear them. In order to effectively avoid various ear diseases caused by in-ear headphones, it has been recommended by otologists and audiologists, and has been recommended by bone conduction headphones many times on the famous medical website "Dr. Lilac".

In terms of the influence of headphones on hearing, because bone conduction headphones transmit sound through the skull, part of the ability will be absorbed by the skull structure when transmitting sound to hair cells, so the damage to hair cells will be reduced by nearly 70% compared with ordinary headphones, and correspondingly, the damage to hearing by bone conduction headphones will be reduced. That's why people say that bone conduction headphones are the ones that do the least harm to the ears.

2. It is safer to wear.

The noise around the bone conduction earphone can still be heard, and general conversation can be carried out, which also prevents the risk of safety accidents caused by not hearing external noise.

Comfortable to wear

Bone conduction headphones do not need to be worn in the ear, so they are more comfortable to wear than ordinary in-ear headphones and will not cause ear pain.

If you are interested in bone conduction headphones, it is easy for some people who don't understand to buy fake bone conduction headphones. Here are some bone conduction headphones that have been tested well, hoping to help you.

First, South Carolina runner pro3 bone conduction headphones

Highlight: excellent bone conduction earphone, mature technology and the best recommendation.

South Carolina insists on technological innovation of bone conduction. Bone vibrator is a leading brand in China and has mastered the core technology of bone conduction. It has been called "the healthiest Bluetooth headset" by many otologists, and has been effectively certified by the team of clove doctors.

As a domestic TOP 1 brand, Nanka has always been in Do not forget your initiative mind, insisting on creating "true" bone conduction. In order to solve the problem of sound quality distortion of traditional bone conduction headphones, South Carolina adopted a new generation of bone vibrator technology, and invited Grammy listeners to customize the exclusive sound quality output scheme for unique bone conduction sound transmission. Twenty-three audiologists adjusted 105063 times day and night, and they have stereo cranial cavity sound quality, showing good sound quality that really belongs to bone conduction.

The wearing of headphones is ergonomically designed. South Carolina combined with the Asian ear database collected by users in the past and 97 engineers in South Carolina, after 197 days and nights of analysis and innovation polishing.

In terms of configuration, South Carolina's Runner Pro3 can be said to be fully loaded, supporting NFC fast pairing and one-drag-two functions, which can realize fast connection and switching of multiple devices. By optimizing the transmission power consumption, the battery life of Bluetooth 5.2 chip is as high as 10 hour.

Second, as660 bone conduction earphone with less sound

Highlight: Good sound quality, wear resistance and high cost performance.

As660 is made of titanium alloy, which is not only flexible, but also flexible. Moreover, the weight is light, and the whole machine is only 29g, so it will not feel the burden at all. If you can't hear songs, it's easy to ignore the existence of AS660. Ergonomic ear patch design makes people feel more comfortable and stable when wearing. Equipped with a new generation of Qualcomm Bluetooth 5.0 three-core chip, the connection with the playback device is very stable and fast. You can connect immediately after 1 sec. LeakSlayer sound leakage elimination technology and integrated 180 phase difference reverse sound leakage elimination technology have effectively improved the common problem of sound leakage in bone conduction headphones.

Third, Philips A6606 bone conduction headphones

Recommended reason: the one with balanced performance and price below 1000 yuan.

This earphone is only 35 grams, and you can hardly feel the weight when wearing it on your head. I think the frosted diaphragm is very skin-friendly and easy to keep clean. Compared with the mesh structure, its advantages are obvious. The back of the earphone is made of high-strength titanium alloy with good toughness, so you don't have to worry about life. The feeling of wearing it is also very comfortable, gently clamped on both sides of the head, and almost can't feel its existence. The waterproof rating of this earphone has reached IP67, so you don't have to worry about sweating and getting wet when exercising. The headset is connected to the mobile phone through Bluetooth 5.2, which is simple and quick to operate.

Four, South Carolina runners cc2 bone conduction headphones

Highlight: South Carolina, a famous brand of bone conduction, has the highest cost performance.

As a cost-effective product, South Carolina runner cc2 bone conduction earphone has a good experience. The earphone body is made of titanium alloy, which is more flexible and durable. The lightweight design of the earphone body only weighs 28g. The waterproof and dustproof level has reached IPX6 level, and even if you sweat, you are not afraid of earphone damage. In terms of sound quality, South Carolina's unique OT closure technology can effectively reduce the phenomenon of sound leakage, thus reducing the troubles caused by vibration, making the low frequency more delicate, the voice more excellent, and bringing a wonderful musical experience.

Five, landscape JG5 bone conduction headphones

Highlight: The price is low, so it can be used as an introduction and an early adopter.

The sound quality experience of this bone conduction earphone is not very good, but the price is relatively low, so it is a good choice as an early adopter. The earphone adopts lightweight body design, and the whole machine is as light as 34g, which brings a more natural and comfortable wearing experience. Select CSR Qualcomm 5.0 Bluetooth chip for fast and stable connection. At the same time, it is equipped with a large-capacity built-in battery, which can stably meet the needs of outdoor use.
