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, the transducer including a magnetic system, wherein the magnetic system includes
a first magnetic component that has a first magnetization direction;
a second magnetic component that has a second magnetization direction; and
a first magnetic conductive component disposed between the first magnetic component and the second magnetic component; and
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, wherein the at least one sound guiding hole includes a damping layer, the damping layer being configured to adjust the phase of the guided sound wave in the target region.
