Chip-level teardown report for wireless headset AirPods: detail design is impressive

OFweek wearable device network news says AirPods looks "bone skeptical", the overall shape makes people feel very abrupt, as if it is pulled from the HardPod on EarPods down. However, through detailed analysis of various parts, it was discovered that Apple is an epoch-making speech augmented reality product. Traditional headphones rely on the audio signal of the device and can only implement various basic functions. AirPods uses a combination of voice acceleration sensors and microphones that use beamforming technology to work together to filter out background noise and lock your voice clearly.

In the market filled with a variety of wireless Bluetooth headsets, the release of AirPods continues to make waves. Apple maintains its brand loyalty to Apple through AirPod. The six-week delivery time fully illustrates this point. .

Traditional headphones rely on the audio signal of the device and can only implement various basic functions. AirPods uses a combination of a voice acceleration sensor and a microphone using beam forming technology to filter out background noise, lock your voice clearly, and pass AI and Siri. Voice creates a foundation for augmented reality, allowing it to have great potential for voice interaction and 3D sound effects.

The following is the "infinite" possible for the SIRI of Shanghai Micro-Tech Industrial Research Institute to explore the AirPods - chip-level dismantling report.

Overall structure

Since the release of AirPods, the industry has already conducted extensive discussion and exploration of the W1 chip. SITRI will focus on the sensor and explore the support points for various powerful features in AirPods.

Speech Acceleration Sensor

The voice acceleration sensor is a voice activity detector that specifically detects vibrations generated by the user. Whether it is the "voiced sound" generated by the user's vocal cords or the "unvoiced sound" produced by the vocal cords, the sensors can be detected through vibrations in the user's muscle tissue and bones. Its package size is 2.0 mm x 2.0 mm x 0.95mm.
