1. An earphone, comprising: a sound production component and a suspension structure, wherein
in a wearing state, the suspension structure is used to place the sound production component at a position near but not blocking an ear canal; and
the sound production component includes:
a housing;
a transducer residing inside a cavity formed by the housing and configured to generate vibrations, the vibrations producing a sound wave inside the housing, and the transducer including a diaphragm; and
at least two sound guiding holes located on the housing and configured to guide the sound wave inside the housing through the at least two sound guiding holes to an outside of the housing, the guided sound wave including at least two guided sound waves having different phases, wherein
the at least two sound guiding holes include a sound outlet, a first pressure relief hole, and a second pressure relief hole,
the sound outlet is disposed on an inner side surface of the housing facing an auricle and is configured to transmit a sound generated at a front side of the diaphragm to the ear canal,
the first pressure relief hole and the second pressure relief hole are disposed respectively on at least another side surface of the housing and are configured to guide sounds generated at a rear side of the diaphragm out of the housing, and
a distance from a center of the sound outlet to a perpendicular bisection-plane of a line segment connecting a center of the first pressure relief hole and a center of the second pressure relief hole is in a range of 0 mm-2 mm.
