Bone Conduction Device
Bone Conduction

Bone conduction is a way to perceive the sound. Compared with air conduction, bone conduction transmits sound waves with no need of passing through eardrums, and the vibrator is used to send sound waves for bone vibration to auditory nerve.

Bone Conduction Characteristics:
1. Reduce the burden of “eardrums” and the risk of hearing loss.
2. Wear the device without blocking the ear, and care for ear canal hygiene and health.
3. Used in music earphones, hearing aid equipment, communication services in noisy environment, IOT sensor application, IOT sensing field, etc.

Bone Conduction

The bone conduction device is a kind of sound conduction device used in hearing equipment (such as earphones and hearing aids). The sound source signal (including electrical signal) is converted into mechanical vibration. The hearing equipment is used to touch the human bone and transmit vibration to human bones so that the people can recognize the sound through bones.

The latest-generation bone conduction device adopted by our company is the micro vibrator with high sensitivity, ultra precision and low energy consumption, having a diameter of only about 10 mm, which simplifies the internal components to the fullest extent and achieves the lightweight integrated design. The ultra-wide frequency range from 4Hz to 40KHz presents extensive sound domain and full sound field, to radiate the new sound sense of Bone Audio and bring pure bone conduction hearing enjoyment.

Bone Conduction
