1. An acoustic output apparatus, comprising:
at least one acoustic driver configured to generate sound that is output through at least two sound guiding holes; and
a supporting structure suitable for wearing on a user's body and configured to support the at least one acoustic driver, the supporting structure and the at least one acoustic driver being not block an ear canal of the user, wherein one of the at least two sound guiding holes is located on a first side of the supporting structure facing the user's ear, and another one of the at least two sound guiding holes is located on a second side of the supporting structure facing away from the user's ear, the supporting structure functions as a baffle to increase an acoustic distance from the another one of the at least two sound guiding holes to the user's ear, wherein
the at least two sound guiding holes are located on a same side of the user's ear, a ratio of a distance between a sound guiding hole, which is closer to the user's ear, of the at least two sound guiding holes and the user's ear to a distance between the at least two sound guiding holes being less than or equal to 3.
