Bone Conduction Bluetooth Glasses Interpretation of Future Trends
How do people hear the sound? Simply put, one is air conduction, where sound passes through the ear canal to vibrate the eardrum to trigger hearing; there is also a bone conduction method, which transmits sound to the auditory nerve through the skull, and skips the ear canal to perceive the sound through the auditory nerve. When applied to the audio product market, the traditional earphones we often use, bone conduction earphones that have been launched by many brands, and smart open-ear audio glasses and bone conduction Bluetooth glasses that are becoming popular nowadays appear. The smart open-ear audio glasses are conducted through air.
Although bone conduction audio products are still relatively niche products in terms of current applications, their history has been very long. The earliest bone conduction earphones were first applied to the medical field in 1935, helping people with hearing loss to hear the information around them.
At the beginning of the 21st century, many manufacturers began to introduce bone conduction audio products for consumer electronics. The main function is to provide users with an open listening experience. While listening to music, they can still easily learn the surrounding sound, which is loved by many sports people. Gradually developed into a category of sports Bluetooth audio products.
This time, Corsca will share with you in detail what bone conduction glasses are, the difference between them and traditional headphones, what bone conduction audio brands are currently on the market, and the future development trend of bone conduction audio products.
1. What are bone conduction glasses?
As the name suggests, bone conduction glasses use bone conduction technology to convert sound into mechanical vibrations of different frequencies, and transmit sound waves through the human skull, bony labyrinth, inner ear lymph, spiral organs, and auditory center. Compared with traditional earphones, the ear canal and tympanic membrane are less involved in the listening process, so it can provide an open listening experience and can also be used by people with damaged eardrums.
The core technology of bone conduction glasses is mainly the sound device-bone conduction vibrator. The pros and cons of bone conduction vibrators directly affect the wearing comfort, sound quality, and battery life. On the other hand, due to the unique sounding method of bone conduction glasses, the technology for improving sound quality is also the key.
At the application level of bone conduction glasses, based on its bone conduction sound transmission method, open wearing and other product characteristics, it is mainly positioned in the sports Bluetooth headset market, which can provide sports users with a more comfortable and safe listening music experience.
At the same time, it is also very attractive to people who don’t like the traditional earplugs and stethoscope effect, wear small ear canals for a long time and the auricle is sore and painful, as well as hearing impairment.
From the above, we have learned the two main characteristics of bone conduction glasses: bone conduction transmits sound and open wear. Let’s take a closer look at the specific differences between bone conduction glasses and traditional headphones.
2. The difference between bone conduction Bluetooth glasses and conventional headphones
<1> Wearing method
The first is the difference in wearing methods. In the current earphone market, traditional earphones mainly include wired earphones, neck-mounted earphones and TWS earphones, and the other is the over-ear wearing of headphones.
Both wearing methods close the ears, so the size of the earplugs and the ear canal does not correspond to the ear canal pain after long-term wearing, the hot summer wearing, the lack of air circulation in the ear canal causes the rapid growth of bacteria, and the long-term high volume stimulation Causes hearing loss and other problems.
Regarding the way of wearing bone conduction glasses, the products currently on the market are mainly worn on the ear, with the memory neckline located behind the head, and the bone conduction vibrator located directly in front of the ear canal.
However, with the development of the market, the product form is also changing, such as Yiou’s ear clip bone conduction headphones and true wireless ear clip bone conduction headphones, which are fixed on the ear cartilage to achieve bone conduction sound transmission. the way.
Both forms belong to an open wearing method during use, and there is no need to block the ear canal when wearing and using, thereby avoiding problems that may occur when wearing traditional earphones.
<2> Music experience
In listening to music, bone conduction Bluetooth glasses provide a brand new listening experience compared to traditional headphones. The open wearing method liberates both ears, allowing users to easily obtain surrounding information while listening to music, and the long-term wearing experience is more comfortable, while also avoiding the risk of eardrum damage.
In terms of sound quality performance, the traditional earphone earphone type and over-ear type wear provide a relatively independent space for listening to music, which can effectively reduce the interference of the external environment and achieve a clearer listening effect. And with the addition of active noise reduction, it has a more immersive music experience.
The sound quality of bone conduction Bluetooth glasses can also meet the needs of daily use, but the overall listening experience will be slightly insufficient compared with the tri-band performance of traditional headphones. The low-frequency performance is the most obvious, lacking the shock of traditional headphones. And for some music with very strong drums, there will be obvious discomfort that the vibrator vibrates the skin.
In terms of loudness, the open ear canal will have an impact. The bone conduction Bluetooth glasses require a larger volume under the same hearing sense. This also leads to another problem-sound leakage. Although with the development of technology, the sound leakage has been obtained. A great improvement, but it still performs significantly compared to traditional headphones.
At present, traditional headset products include wired headsets, TWS headsets, neck-mounted Bluetooth headsets, head-mounted Bluetooth headsets, and sports ear-hook headsets, covering all aspects of daily commuting, sports, fitness, and entertainment.
Bone conduction Bluetooth glasses are relatively specific, and consumer-grade products are currently mainly positioned in the sports headset market. The wearing style of the open ear canal allows you to learn about the surrounding environment sound during jogging, cycling, mountaineering and other sports, and has a higher sense of wearing security. The bone conduction sound transmission method can also better deal with wind noise.
In general, bone conduction Bluetooth glasses have absolute advantages in the wearing experience, but at the same time they also bring deficiencies in the music experience. While the open wearing experience liberates the ear canal, it is also accompanied by problems such as relatively insufficient sound quality and sound leakage. And with the application of active noise reduction to traditional headphones, the disadvantage of audio experience has been further enlarged.
However, in its dedicated sports earphone market, bone conduction Bluetooth glasses have advantages that traditional earphones cannot reach, and can provide sports enthusiasts with a more comfortable and safe listening experience.
3. Bone conduction headset brands currently on the market
In the current bone conduction audio product market, thanks to the growth of the entire headset market, bone conduction headsets and bone conduction Bluetooth glasses also maintain rapid growth. Among them, Aftershokz is still the largest manufacturer in the industry, followed by brands such as Marsboy, Audio Bone, Invisio, Damson Audio, Motorola, Sainsonic, KSCAT, ABCO Tech, earsopen, etc.
In addition, Philips, Shanshui, South Carolina, Newman, Patriot and other brands are also rapidly deploying the bone conduction headset market. There are already many bone conduction audio brands, the competition is relatively fierce, and new brands are still being added.
The 2014-2025 market report released by the well-known research organization QYR, history and forecasts show that the global bone conduction audio product market has grown from US$31.94 million in 2014 to US$160.34 million in 2018. It is predicted that by 2025, this figure will reach 939.06 million U.S. dollars, and the compound annual growth rate from 2019 to 2025 is predicted to reach 27.19%. The future development of the bone conduction audio product market will continue to show a rapid growth trend.
4. The future development trend of bone conduction headphones
The progress of Bluetooth and related technologies has driven the wireless era of Bluetooth audio products, providing users with a more convenient experience, and has gradually gained market recognition. Audio products such as Bluetooth headsets and smart audio glasses have ushered in a rapid growth stage.
Bone conduction audio glasses, as a very important category in the current Bluetooth headset market, have an open wearing experience and a listening experience different from traditional headsets. At present, they are mainly focused on the sports headset market. However, the development of bone conduction audio glasses is more than that. According to the advantages of its characteristics, it will gradually be applied to many fields in the future.
Bone conduction hearing aid earphones
Bone conduction earphones use a bone conduction vibrator to directly transmit sound to the auditory nerve, so that it bypasses the tympanic membrane of the human ear. Bone conduction earphones can collect surrounding sounds through the participation of other devices, and then output to users through bone conduction, which can help some people with damaged or aging eardrums to better receive external information and achieve the function of hearing aid.
Bone conduction children’s headset
For children, the development of the Internet has made it easier to receive education, but the number of times children use headphones is also increasing rapidly. However, because the children’s body structure is still in the developing stage, the eardrum is more susceptible to damage from external stimuli. The open wearing and listening experience of bone conduction earphones can effectively avoid the possible impact of in-ear earphones on children’s hearing and help children grow up healthier.
Bone conduction customer service, takeaway earphones
The advantages of bone conduction headphones are very suitable for use in some occupations. Takeaway riders are the busiest group of people during meal time. They shuttle on busy roads. In order to achieve maximum efficiency, takeaway riders need to communicate with merchants and users in real time. The open listening experience of bone conduction headphones can be It helps them learn the surrounding safety information at the same time during the call.
Customer service staff is the busiest profession every day, requiring a full day of voice calls. The way the bone conduction headset transmits sound can effectively protect the hearing of the operator and prevent damage to the long-term conversation.
Bone conduction headphones+
In addition to the advantages of the above bone conduction headsets that can meet the needs of different people and different scenarios, it can also be used in combination with other products such as smart AR/VR/MR glasses, smart helmets, diving equipment, etc. in the form of audio solutions to create more comfortable And a safe listening experience.
Bone conduction Smart glasses is an important solution for audio products at present. Although the status of traditional headphones cannot be touched in application, its open wearing experience and bone conduction way of transmitting sound can provide more comfortable and safer The listening effect is also currently unattainable by traditional earphones, which is why bone conduction earphones can maintain steady growth in today’s explosive phase of traditional Bluetooth earphones.
In terms of the market, many brands have joined the competition of bone conduction Bluetooth glasses, with product prices ranging from one hundred yuan to thousands of yuan. However, the music experience different from TWS earphones only affects individuals. Bone conduction earphones will affect the surrounding people due to sound leakage, and have higher technical requirements. Therefore, high-quality products will continue to expand their advantages, and poor products will be quickly eliminated.
In terms of application, the current bone conduction Bluetooth glasses are mainly positioned in the sports field, and there are relatively few others. However, with the advancement of various technologies and the continuous improvement of functions of bone conduction headsets, in the future, it will gradually expand to more Bluetooth headset markets such as hearing aids, health, etc., and to be applied to more electronic devices. Improve the actual user experience of users.
