1. A speaker, comprising:
a housing;
a transducer residing inside the housing and configured to generate vibrations, the vibrations producing a sound wave inside the housing and causing a leaked sound wave spreading outside the housing from a portion of the housing;
at least one sound guiding hole located on the housing and configured to guide the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing, the guided sound wave having a phase different from a phase of the leaked sound wave, the guided sound wave interfering with the leaked sound wave in a target region; and
a first microphone and a second microphone disposed in the housing, wherein the first microphone and the second microphone are disposed at different positions of a circuit board.
