In the market filled with a variety of wireless Bluetooth headsets, the release of Apple's next-generation wireless headset AirPods is still a huge wave. Apple maintains consumer brand loyalty to Apple through AirPod, and the six-week delivery time fully illustrates this. Traditional headphones rely on the device's audio signals to perform only a variety of basic functions, while AirPods works in a tacit collaboration with a microphone using beamforming technology to filter out background noise, clearly lock your voice, and pass AI and Siri. Voice creates a foundation for augmented reality, making it a great potential for voice interaction and 3D sound.
Overall structure
At the beginning of the release of AirPods, the industry has already discussed and explored the W1 chip extensively. SITRI will focus on the sensor and explore the support points of various powerful functions in AirPods.
The voice acceleration sensor is a voice activity detector that specifically detects the vibration generated by the user. Whether it is the “voiced sound†produced by the user's vocal cords or the “unvoiced sound†produced by the vocal cords, the sensor can be detected by the vibrations in the user's muscle tissue and bones. The package size is 2.0 mm x 2.0 mm x 0.95mm.
