通过⽿机内⻨克⻛收集到的⽤⼾语⾳，有机会给周边环境噪声所影响。
振动传感器通过⻣骼和组织振动捕捉⽤⼾的语⾳，不受环境噪⾳影响，但其频率受到1 kHz的限制。
⻨克⻛信号中的声学回声和⻣传导信号中潜在的“振动回声”被消除。
利⽤降噪技术对声学和⻣传导语⾳信号进⾏清理。
⻨克⻛信号采⽤⾃适应波束成形技术进⾏增强，该技术在⾼频率下最为有效，并与⻣传导信号中的低频结合。
通过声学和⻣传导信号中语⾳和噪声的级别和频谱控制进⾏智能混合，以实现最佳声⾳质量。
-
The user's speech picked up by the microphones in the earpiece maybe contaminated by ambient noise.
-
The vibration sensor captures the user's speech via bone and tissue vibrations that is free of acoustic noise but limited to a frequency of 1 kHz.
-
Acoustic echoes in the microphone signals and potential "vibration echoes" in the bone conduction signal are cancelled.
-
Acoustic and bone-conducted speech signals are cleaned up using noise reduction technology.
-
Microphone signals are enhanced with adaptive beamforming technology, which is most efficient at high frequencies, and mixed with the bone conduction signal at low frequencies.
-
Intelligent mixing is controlled by the levels and spectra of speech and noise in the acoustic and bone-conducted signals to achieve the best sound quality.
2022年消费电子市场低迷，但是展望2023年，以手机为代表的消费电子市场将复苏，而TWS耳机也将扩大渗透率，苹果系TWS渗透率比较高，而安卓系阵营将成为TWS的重要增长点。降本，增效，提高自动化将成为行业热点话题。为了进一步促进TWS产业交流，艾邦新建TWS产业链微信群，欢迎申请加入群聊。
