Abstract
A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.
Claims20
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;
- 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, and the interference reducing a sound pressure level of the leaked sound wave in the target region, wherein the interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.
The speaker of claim wherein a shape of the at least one sound guiding hole is circle, ellipse, quadrangle, rectangle or linear.
