1. An acoustic output apparatus, comprising:
at least one acoustic driver configured to output sounds with opposite phases through at least two sound guiding holes, the at least two sound guiding holes including a first sound guiding hole and a second sound guiding hole; and
a supporting structure, the supporting structure being configured to support the at least one acoustic driver, both the supporting structure and the acoustic driver approach but not block a user's ear canal, wherein:
the at least one acoustic driver includes a vibration diaphragm, a first acoustic route from the vibration diaphragm to the first sound guiding hole is different from a second acoustic route from the vibration diaphragm to the second sound guiding hole,
the first and second sound guiding holes are located on a same side of the user's ear canal, and
a ratio of a distance between the user's ear canal and a sound guiding hole that is closer to the user's ear canal among the first and second sound guiding holes to a distance between the first and second sound guiding holes is less than or equal to 1.
