5. The acoustic output apparatus of claim 4 , wherein the one or more sensors detect a point of interest (POI) that the user is proximate to or facing towards.

6. The acoustic output apparatus of claim 1 , wherein the controller is further configured to cause the at least one acoustic driver to output sound based on the detected status information of the user.

7. The acoustic output apparatus of claim 6 , wherein to cause the at least one acoustic driver to output sound based on the detected status information of the user, the controller is further configured to

determine an audio message related to the POI; and

cause the earphone core to replay the audio message upon the detection of the POI by the one or more sensors.

9. The acoustic output apparatus of claim 1 , further comprising:

an active noise reduction module configured to generate, according to detected noise, an anti-noise acoustic signal to reduce the detected noise within the output sound.

10. The acoustic output apparatus of claim 1 , wherein the controller causes the low-frequency acoustic driver to output sound in a first frequency range and the high-frequency acoustic driver to output sound in a second frequency range, and the second frequency range including frequencies higher than the first frequency range.

11. The acoustic output apparatus of claim 10 , wherein the first frequency range and the second frequency range at least in part overlap.

12. The acoustic output apparatus of claim 10 , further comprising:

an electronic frequency division module configured to decompose a source signal into 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 drives the low-frequency acoustic driver to generate sound, and the high-frequency signal drives the high-frequency acoustic driver to generate sound.

13. The acoustic output apparatus of claim 1 , wherein

the low-frequency acoustic driver and the at least two first sound guiding holes form a first acoustic route,

the high-frequency acoustic driver and the at least two second sound guiding holes form a second acoustic route, and

the first acoustic route and the second acoustic route have different frequency selection characteristics.

14. The acoustic output apparatus of claim 1 , wherein there is a first distance between the two first sound guiding holes and a second distance between the two second sound guiding holes, the first distance being larger than the second distance.

15. The acoustic output apparatus of claim 1 , further comprising:

a supporting structure configured to carry the low-frequency acoustic driver and the high-frequency acoustic driver and position the at least two first sound guiding holes and the at least two second sound guiding holes away from a position of the user's ears.
