Claim 0:
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 the interference reducing a sound pressure level of the leaked sound wave in the target region;
a microphone configured to receive a first signal including a voice signal and a first vibration signal; and
a vibration sensor configured to receive a second vibration signal, wherein
the microphone and the vibration sensor are configured such that the first vibration signal can be offset with the second vibration signal.
