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

Abstract: A BLUETOOTH communications system includes a true wireless stereo (TWS) BLUETOOTH headset and a terminal device, where the TWS Bluetooth headset includes a first earbud and a second earbud. The terminal device controls the first earbud to collect a sound signal and the second earbud to play a sound signal. When an audio application on the terminal device is started, the first earbud collects a first sound signal, performs sound effect processing on the first sound signal to obtain a second sound signal, and sends the second sound signal to the second earbud. The terminal device sends accompaniment audio to the second earbud, and the second earbud performs audio mixing processing on the accompaniment audio and the second sound signal for playing.
