1. A speaker, comprising:
a housing, the housing having an inner side facing the user;
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; and
at least one sound guiding hole located on the inner side, the at least one sound guiding hole being configured to guide the sound wave inside the housing through the at least one sound guiding hole to an ear canal of the user and to a target region in surrounding environment, the sound wave guided to the target region having a phase different from a phase of the leaked sound wave, the sound wave guided to the target region interfering with the leaked sound wave, and the interference reducing a sound pressure level of the leaked sound wave in the target region.
