1. An earphone, comprising:
a sound production component including:
a transducer including a diaphragm used to produce a sound under an action of an excitation signal; and
a housing, the housing forming a cavity used to accommodate the transducer; 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, wherein
an inner side surface of the housing facing an auricle is provided with a sound outlet that is configured to transmit a sound generated at a front side of the diaphragm to the ear canal,
at least another side surface of the housing is provided with a first pressure relief hole that is configured to guide a sound generated at a rear side of the diaphragm out of the housing, and
a distance between a center of the sound outlet and a midpoint of an upper boundary of the inner side surface is greater than a distance between a center of the first pressure relief hole and the midpoint of the upper boundary of the inner side surface.
