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.
