With the rapid growth of the TWS (True Wireless Stereo) headset market, user demand for sound quality and functionality is also rising. Against this backdrop, bone vibration sensors, as a breakthrough technology, are gradually becoming a standard feature of high-end TWS headphones. In this article, UCC will lead readers to an in-depth discussion of the working principle of bone vibration sensors, their application in TWS headphones, and the future development trend.

The working principle of bone vibration sensor

Bone vibration sensors are based on the principle of bone conduction and capture voice signals by detecting the tiny vibrations of the human skull and auricle. Compared with conventional microphones, bone vibration sensors are insensitive to airborne sound waves and therefore can effectively suppress interference from ambient noise. A good quality bone vibration sensor usually has the following characteristics:

A resonant frequency of approximately 4kHz, which matches the frequency range of the human voice.

Signal-to-noise ratio of more than 55dB, ensuring clear capture of the speech signal.

Small size for easy integration into compact TWS headsets

Main applications in TWS headsets

Enhancement of call quality: The bone vibration sensor captures the user's voice signal clearly while effectively suppressing background noise. Combined with traditional microphone signals, this technology significantly improves call clarity, especially in noisy environments.

Improved Voice Interaction: Through bone conduction signals, TWS headset can more accurately determine whether the user is speaking or not, thus improving the accuracy of voice wake-up and interaction and reducing false triggers.

Enables accurate wear detection: Bone vibration sensors can detect whether the headphones are correctly worn on the ear, enabling automatic start and pause playback, which greatly enhances the user experience.

Enhances active noise cancellation: Bone conduction signals can be used as a reference for active noise cancellation algorithms, helping the headphones to more accurately identify and eliminate external noise and provide better noise cancellation.

Support health monitoring function: By analysing the characteristics of bone conduction signals, TWS headphones can even monitor physiological indicators such as heart rate and blood pressure, bringing additional health monitoring functions to users.

Future Development Trends

The continuous advancement of bone vibration sensor technology bodes well for its wider application in TWS headsets. Future developments may include:

Further improvements in signal-to-noise ratio and sensitivity to capture fainter bone conduction signals

Shrinking the size of the sensors and reducing power consumption to make them easier to integrate

Developing innovative applications based on bone conduction signals, such as emotion recognition

Conclusion

Bone vibration sensor technology not only brings new possibilities for TWS headphones, but is also expected to become a standard technology for high-end products. With the maturity of the technology and the depth of its application, it will bring users a smarter and better audio experience and lead the technological innovation of the TWS headset industry.
