The human ear audible frequency range is 20Hz-20KHz, and the speaker transmission mode is divided into air conduction (AC) and bone conduction. Bone conduction (BC)
AC is the sound signal generated by the vibrating diaphragm, and BC is the direct transmission of the audio vibration to the skull. AC path: auricle – external auditory canal – tympanic membrane – hammer bone – anvil – humerus – vestibular window – external, endolymphatic – auger – auditory nerve – auditory central BC path: skull – bone labyrinth – inner ear lymph – screw – auditory nerve – Auditory center
Advantage of Bone Conduction Headphones:
The bone conduction exercise earphone does not need to transmit sound through the ear canal, so it is not necessary to cover the ear or block the ear canal to achieve the purpose of listening to the sound like a traditional earphone. When you use the bone conduction earphone, you can also hear the surrounding. The environmental sound, “open ear listening” can avoid some dangerous situations, which is the most worthy of the current bone conduction headphones.
The bone conduction earphone does not need to put the earplug into the human ear, and can keep the inside of the ear canal clean and hygienic. At the same time, the bone conduction earphone has a smooth surface and is easy to clean, and the traditional air conduction earphone is easy to deposit bacteria inside.
Traditional earphones need to be inserted into the ear for a long time, which will gradually have a negative impact on the user’s hearing. And bone conduction can better protect our hearing.
