1. A method, comprising:
providing a speaker including:
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 at least from a portion of the housing; and
at least two sound guiding holes located on the housing and configured to guide the sound wave inside the housing through the at least two sound guiding holes 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, the interference reducing a sound pressure level of the leaked sound wave in the target region, wherein
the at least two sound guiding holes include a first sound guiding hole and a second sound guiding hole, a first distance between the first sound guiding hole and the portion of the housing is larger than a second distance between the second sound guiding hole and the portion of the housing.
