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: An audio processing method includes establishing a wireless connection between a wireless headset and an electronic device, and establishing a wireless connection between the wireless headset and a charging case. The charging case collects a sound signal, generates first audio data, and sends the first audio data to the wireless headset. The wireless headset performs audio effect processing on the first audio data to obtain second audio data. The electronic device sends third audio data to the wireless headset. The wireless headset performs audio mixing processing on the second audio data and the third audio data to obtain fourth audio data and plays the fourth audio data.
