-
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年消費(fèi)電子市場(chǎng)低迷,但是展望2023年,以手機(jī)為代表的消費(fèi)電子市場(chǎng)將復(fù)蘇,而TWS耳機(jī)也將擴(kuò)大滲透率,蘋(píng)果系TWS滲透率比較高,而安卓系陣營(yíng)將成為T(mén)WS的重要增長(zhǎng)點(diǎn)。降本,增效,提高自動(dòng)化將成為行業(yè)熱點(diǎn)話題。為了進(jìn)一步促進(jìn)TWS產(chǎn)業(yè)交流,艾邦新建TWS產(chǎn)業(yè)鏈微信群,歡迎申請(qǐng)加入群聊。
