The first sound sensor module includes N sound sensors. The noise reduction circuit determines, based on a target direction from which ambient noise comes, N weights corresponding to the N sound sensors, so that a phase of an integrated ambient noise signal measured by the first sound sensor module based on the N weights is ahead of a phase of the ambient noise reaching a sound output end of the speaker. The noise reduction circuit generates a first noise cancellation signal based on N individual ambient noise signals captured by the N sound sensors, and the N weights. The speaker converts the first noise cancellation signal into a first noise cancellation audio, thereby achieving noise reduction.
