Acoustic output apparatus and method thereof

1 . An acoustic output apparatus, comprising:

an earphone core including at least one acoustic driver for outputting sound through at least one sound guiding hole;

one or more sensors configured to detect status information of a user; and

a controller configured to cause the at least one acoustic driver to output sound based on the detected status information, wherein the at least one acoustic driver includes a low-frequency acoustic driver that outputs sound from at least two first sound guiding holes and a high-frequency acoustic driver that outputs sound from at least two second sound guiding holes, and the controller is configured to: cause the acoustic output apparatus to focus on sound received from a virtual audio cone based on a point of interest (POI).

2 . The acoustic output apparatus of claim 1 , wherein the at least one sound guiding hole includes two or more sound guiding holes, and to cause the at least one acoustic driver to output sound based on the detected status information, the controller is further configured to:

transmit the sound from different sound guiding holes in the two or more sound guiding holes to simulate sound effects of different directions.

3 . The acoustic output apparatus of claim 1 , wherein the one or more sensors is further configured to detect the POI that the user is proximate to or facing towards.

4 . The acoustic output apparatus of claim 3 , 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 at least one acoustic driver to replay the audio message upon the detection of the POI by the one or more sensors.

5 . The acoustic output apparatus of claim 4 , wherein to determine the audio message related to the POI, the controller is configured to:

generate information based at least in part on sensor data detected by the one or more sensors; and

determine the audio message related to the POI based on the generated information.

6 . The acoustic output apparatus of claim 5 , wherein to generate information based at least in part on sensor data detected by the one or more sensors, the controller is configured to:

generate a representation by weighting at least one of the sensor data, user data of the user, a demographic profile of a plurality of users with at least one common attribute with the user, a categorical popularity of an audio file.

7 . The acoustic output apparatus of claim 4 , wherein to cause the at least one acoustic driver to replay the audio message upon the detection of the POI by the one or more sensors, the controller is configured to:

obtain sensor data detected by the one or more sensors;

determine whether the user is proximate to or facing towards the POI based on the sensor data; and

in response to determining that the user is proximate to or facing towards the direction of the POI, cause the at least one acoustic driver to replay the audio message.

8 . The acoustic output apparatus of claim 1 , wherein to cause the acoustic output apparatus to focus on sound received from a virtual audio cone based on a POI, the controller is configured further to:

reduce sound outside of the virtual audio cone from being heard by the user using an active noise reduction (ANR) technique.

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

determine an audio message related to the POI; and

cause the at least one acoustic driver to output sound by overlaying the audio message on the sound received from the virtual audio cone.

10 . The acoustic output apparatus of claim 1 , wherein the controller is further configured to provide a virtual user-interface through which a user interacts with the acoustic output apparatus.

11 . The acoustic output apparatus of claim 10 , wherein to cause the at least one acoustic driver to output sound based on the detected status information, the controller is further configured to:

determine one or more audio messages based on the detected status information;

causing the acoustic output apparatus to display a plurality of zones via the virtual user-interface, each of the plurality of zones corresponding to one of the one or more audio messages;

receive, from the user, a selection of a zone from the plurality of zones; and

cause the at least one acoustic driver to replay an audio message corresponding to the zone.

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

13 . The acoustic output apparatus of claim 10 , wherein the user interacts with the acoustic output apparatus through at least one of gestures of a body of the user or a voice command.

14 . The acoustic output apparatus of claim 1 , wherein the status information of the user includes at least one of a location of the user, a gesture of the user, a direction that the user faces, an acceleration of the user, or a speech of the user.

15 . The acoustic output apparatus of claim 1 , wherein the one or more sensors include at least one of a locating sensor, an orientation sensor, an inertial sensor, an audio sensor, or a wireless transceiver.

16 . 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.

17 . 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.
