Problems solved by technology

[0003] However, when recording video in a noisy environment, the sound pickup and noise reduction scheme adopted by the existing TWS earphones is limited by the number of microphones in the earphones and the influence of the user's wearing posture.
TWS earphones are less effective in suppressing environmental noise and enhancing the target sound

Abstract

The invention discloses a sound acquisition method, electronic equipment and a system. The system comprises a first electronic device, a left ear TWS earphone and a right ear TWS earphone. In the method, microphones of a first electronic device, a left-ear TWS earphone and a right-ear TWS earphone can form a first microphone array. When the first electronic device detects a user operation of starting video recording, the first microphone array performs sound acquisition to obtain a combined microphone array signal. The first electronic device may perform noise reduction processing on the joint microphone array signal. According to the method, the target sound signal in the near-field area of the first microphone array can be enhanced, the environmental noise signal can be suppressed, and the sound quality in the recorded video can be improved.

Description

technical field [0001] The present application relates to the field of terminal technologies, and in particular, to a sound collection method, electronic device and system. Background technique [0002] With the development of Bluetooth technology, true wireless stereo (TWS) headsets can transmit audio signals more efficiently and with high quality with electronic devices such as mobile phones and tablet computers, and are favored by more and more users. The user can collect sound through the microphone of the TWS headset in a video recording scenario such as live broadcast or video blog (video blog, vlog) shooting. [0003] However, when recording video in a noisy environment, the sound pickup and noise reduction scheme adopted by the existing TWS headset is limited by the number of microphones in the headset and the user's wearing posture. TWS earphones are less effective at suppressing ambient noise and enhancing target sound. SUMMARY OF THE INVENTION [0004] The pre...
