Chinese-English Translation:

骨传导耳机也被称作骨导耳机、骨感耳机、骨传耳机和骨传感耳机,是利用骨传导这种声音传导方式设计制作的耳机,即将声音转化为不同频率的机械振动,通过人的颅骨、骨迷路、内耳淋巴液、螺旋器、听神经、听觉中枢来传递声波。

Bone conduction earphone is also called bone conduction earphone, bone sense earphone, bone transmitting earphone and bone sensing earphone. It is designed and manufactured by using bone conduction, which converts sound into mechanical vibration of different frequencies, and transmits sound wave through human skull, bone labyrinth, inner ear lymph, spiral, auditory nerve and auditory center.

骨传导是一种声音传导方式,即将声音转化为不同频率的机械振动,通过人的颅骨、骨迷路、内耳淋巴液、螺旋器、听神经、听觉中枢来传递声波。

Bone conduction is a way of sound transmission, that is, sound is transformed into mechanical vibration of different frequencies, and sound waves are transmitted through human skull, bone labyrinth, inner ear lymph, spiral organ, auditory nerve and auditory center.

相对于通过振膜产生声波的经典声音传导方式,骨传导省去了许多声波传递的步骤,能在嘈杂的环境中实现清晰的声音还原,而且声波也不会因为在空气中扩散而影响到他人。骨传导技术分为骨传导扬声器技术和骨传导麦克风技术:

Compared with the classical sound transmission mode of sound wave generated by diaphragm, bone conduction saves many steps of sound transmission, and can achieve clear sound reduction in noisy environment, and the sound wave will not affect others because of its diffusion in the air. Bone conduction technology is divided into bone conduction loudspeaker technology and bone conduction microphone technology

(1)骨传导扬声器技术用于送话,送话即听取声音。气导扬声器是把电信号转化为声波(振动信号)传至听神经。而骨传导扬声器则是电信号转化的声波(振动信号)直接通过骨头传至听神经。声波(振动信号)的传递介质不同。

(1) Bone conduction loudspeaker technology is used to send a message, which is to listen to the voice. Air conduction loudspeaker is to convert electrical signals into sound waves (vibration signals) and transmit them to the auditory nerve. The bone conduction loudspeaker is the sound wave (vibration signal) transformed by electrical signal, which is transmitted directly to the auditory nerve through the bone. The transmission medium of sound wave (vibration signal) is different.

(2)骨传导麦克风技术用于受话,受话即收集声音。气导送话是声波通过空气传至麦克风,而骨传导送话则直接通过骨头传递。

(2) Bone conduction microphone technology is used for receiving calls, that is, collecting sound. Air conduction is the transmission of sound waves through the air to the microphone, while bone conduction is transmitted directly through the bone.

利用这些骨传导技术制造的耳机,称之为骨传导耳机,也被称作骨导耳机、骨感耳机、骨传耳机和骨传感耳机。

The earphones made by these bone conduction technologies are called bone conduction earphones, which are also called bone conduction earphones, osseous earphones, bone transmitting earphones and bone sensing earphones.

骨传导耳机分为骨传导扬声器技术耳机、骨传导麦克风技术耳机

Bone conduction earphone can be divided into bone conduction loudspeaker technology earphone and bone conduction microphone technology earphone

(一)骨传导扬声器技术耳机:

(1) Bone conduction loudspeaker technology earphone:

利用骨传导技术受话,紧贴骨头,声波直接通过骨头传至听神经。因此可以开放双耳,不伤害鼓膜。军民领域,一般都是利用面部颊骨直接传导声音。

Bone conduction technology is used to receive the speech, which is close to the bone, and the sound wave is transmitted directly to the auditory nerve through the bone. Therefore, both ears can be opened without damaging the tympanic membrane. In the field of military and civil use, facial cheek bones are generally used to conduct sound directly.

(二)骨传导麦克风技术耳机:

(2) Bone conduction microphone technology headset:

利用骨传导技术收集声音,声波通过骨头传至麦克风。民用领域中,一般都是采用骨传导技术降噪。

Bone conduction technology is used to collect sound, which is transmitted to the microphone through the bone. In the civil field, bone conduction technology is generally used to reduce noise.

由于军事场景需要,有时不能大声讲话,而声音在骨头传导的损失率远远低于空气传导,而骨传导麦克风技术耳机主要是利用喉咙骨头传导。由于距离近,损耗低。士兵只需要发出很小的声音就能准确传递想表达的指令。

Due to the need of military scene, sometimes we can’t speak loudly, and the loss rate of sound in bone conduction is far lower than that in air conduction, and bone conduction microphone technology earphone mainly uses throat bone conduction. Due to the short distance, the loss is low. A soldier needs only a very small voice to deliver exactly what he wants to say.

起源

origin

当我们吃饼干的时候,我们能够听到饼干碎裂的声音就是因为振动通过我们的牙齿和头骨传递到我们的内耳。当我们日常吃东西、喝水或者挠头的时候,都可以听到骨传导的声音。

When we eat biscuits, we can hear the crackle of biscuits because the vibration is transmitted through our teeth and skulls to our inner ears. When we eat, drink or scratch our head, we can hear the sound of bone conduction.

实际上,早在 18 世纪,骨传导的原理就帮助双耳失聪的伟大作曲家贝多芬重新听到了美妙的音乐。贝多芬当时尝试了由乔瓦尼.菲利波.英格拉西亚发明的一项技术,他咬着一根与钢琴相连的棍子就可以听到由颚骨传来的音乐,这其实就是声音的骨传导原理的早期应用。

In fact, as early as the 18th century, the principle of bone conduction helped Beethoven, a great composer with deafness, to hear wonderful music again. Beethoven tried a technique invented by Giovanni Filippo Ingrassia. He could hear music from his jawbone by biting a stick attached to the piano. This was actually an early application of the bone conduction principle of sound.

骨传导技术主要应用在军警专业耳机、助听器、运动耳机等领域。

Bone conduction technology is mainly used in military and police professional headphones, hearing aids, sports headphones and other fields.

工作原理

working principle

在正常情况下,声波通过空气传导、骨传导两条路径传入内耳,然后由内耳的内、外淋巴液产生振动,螺旋器完成感音过程,随后听神经产生神经冲动,呈递给听觉中枢,大脑皮层综合分析后,最终“听到”声音。也许对于空气传导(路径为声波-耳廓-外耳道-鼓膜-锤骨-砧骨-镫骨-前庭窗-外、内淋巴-螺旋器-听神经-听觉中枢),我们或多或少还都有些感性认识,但是对骨传导,则有些不知所云了。也许举个例子你就明白了:用双手捂住耳朵,自言自语,无论多么小的声音,我们都能听见自己说什么,这就是骨传导作用的结果。

Under normal circumstances, sound waves are transmitted to the inner ear through air conduction and bone conduction, and then vibration is generated by the internal and external lymph of the inner ear. The spiral instrument completes the sound sensing process. Then, the auditory nerve generates nerve impulses and presents them to the auditory center. After comprehensive analysis of the cerebral cortex, the sound is finally “heard”. Perhaps we still have more or less some perceptual knowledge about air conduction, but we have no idea about bone conduction. Perhaps you can see, for example, that by covering our ears with our hands and talking to ourselves, we can hear what we say no matter how small the sound is. This is the result of bone conduction.

骨传导有移动式和挤压式两种方式,二者协同可刺激螺旋器引起听觉,其具体传导途径为:“声波-颅骨-骨迷路-内耳淋巴液-螺旋器-听神经-大脑皮层听觉中枢”。通常人们也并不需利用自己的颅骨去感受声音,但是,当外耳和中耳的病变使声波传递受阻时,则可以利用骨传导来弥补听力。如骨传导式助听器、骨传导式耳机等,就是利用骨传导来感受声音的。

There are two ways of bone conduction: moving and squeezing. They can stimulate the spiral organ to cause hearing. The specific conduction pathway is “sound wave skull bone labyrinth inner ear lymph spiral organ auditory nerve cerebral cortex auditory center”. Usually people don’t need to use their own skull to feel sound, but when the external and middle ear lesions hinder sound transmission, bone conduction can be used to compensate for hearing. Such as bone conduction hearing aids, bone conduction earphones and so on, is to use bone conduction to feel sound.

多数下,接触到的耳机都是通过“空气传导”,称之为“空气传导耳机”;而骨导原理生产的耳机把它叫做“骨传导耳机”。

Most of the time, the earphones contacted are through “air conduction”, which is called “air conduction earphone”; while the earphone produced by bone conduction principle calls it “bone conduction earphone”.

骨传导耳机特点

Characteristics of bone conduction earphone

(1)骨传导扬声器技术耳机:

(1) Bone conduction loudspeaker technology earphone:

佩戴使用时开放双耳,不堵塞耳朵,解决了入耳式耳机佩戴的不适感。

When wearing and using, both ears are opened and the ears are not blocked, which solves the discomfort of wearing in ear earphones.

同时,也避免了戴耳机运动时耳内出汗带来的一系列卫生和健康问题。因此,骨传导扬声器耳机十分适合用来运动使用。

At the same time, it also avoids a series of health and health problems caused by sweating in the ear when wearing earphones. Therefore, bone conduction loudspeaker earphone is very suitable for sports use.

开放双耳也保证了危险场景下耳机使用的可能性。打开双耳,使用耳机的同时也能注意到周围环境的变化,使用更加安全。

Open ears also ensure the possibility of headphones in dangerous situations. Open both ears, use headphones can also pay attention to the changes in the surrounding environment, more safe to use.

(2)骨传导麦克风技术耳机:

(2) Bone conduction microphone technology headset:

由于收集声音的距离近,损耗低。能够在说话音量很小时也能让对方清楚知道表达的指令,主要用于军事领域。

Due to the short distance of collecting sound, the loss is low. It can also let the other party clearly know the instructions expressed when the volume is very small, which is mainly used in the military field.
