Claim 18:
19. 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;
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; and
at least one acoustic route coupled to the at least one sound guiding hole, wherein the guided sound wave is propagated to the at least one sound guiding hole along the acoustic route, wherein
the at least one acoustic route being configured to reduce a sound pressure level of the guided sound wave in a first frequency range in a target region, and
the guided sound wave interferes with the leaked sound wave in a second frequency range in a target region, the interference reducing a sound pressure level of the leaked sound wave in the second frequency range in the target region.
