1. An earphone, comprising:
at least one low-frequency acoustic driver configured to output sounds from at least two first guiding holes, wherein the at least two first guiding holes include a near-ear first guiding hole closest to an ear hole of a user among the at least two first guiding holes and a far-ear first guiding hole that is farther from the ear hole of the user than the near-ear first guiding hole, and a ratio of an aperture of the near-ear first guiding hole to an aperture of the far-ear first guiding hole is not less than 1;
at least one high-frequency acoustic driver configured to output sounds from at least two second guiding holes, wherein the at least two second guiding holes include a near-ear second guiding hole closest to the ear hole of the user among the at least two second guiding holes, and a distance between the near-ear first guiding hole or the near-ear second guiding hole and the ear hole of the user is not larger than 2 cm; and
a controller configured to direct the low-frequency acoustic driver to output the sounds in a first frequency range and direct the high-frequency acoustic driver to output the sounds in a second frequency range, the second frequency range including one or more frequencies higher than one or more frequencies in the first frequency range.
