1. An acoustic output apparatus, comprising:
at least one low-frequency acoustic driver that outputs sound in a first frequency range from at least two first sound guiding holes;
at least one high-frequency acoustic driver that outputs sound in a second frequency range from at least two second sound guiding holes, wherein the second frequency range includes frequencies higher than the first frequency range;
a supporting structure configured to carry the at least one high-frequency acoustic driver and the at least one low-frequency acoustic driver, wherein the low-frequency acoustic driver is packaged by a casing, the casing forms a front chamber and a rear chamber of the low-frequency acoustic driver, the front chamber of the low-frequency acoustic driver is acoustically coupled to one of the at least two first sound guiding holes, and the rear chamber is acoustically coupled to another one of the at least two first sound guiding holes, wherein the first frequency range is less than a first frequency threshold, the second frequency range is greater than a second frequency threshold, the first frequency threshold is lower than the second threshold; and
an electronic frequency division module, configured to divide a frequency of a sound source signal to generate a low-frequency signal corresponding to the first frequency range and a high-frequency signal corresponding to the second frequency range, wherein the low-frequency signal corresponding to the first frequency range and the high-frequency signal corresponding to the second frequency range is generated based on a frequency division point, and the frequency division point is a frequency point corresponding to a volume of a leaked sound.
