1. An audio apparatus for outputting an audio signal provided by an electronic device, the audio apparatus comprising:
at least one microphone configured to acquire an ambient sound of the audio apparatus;
a speaker configured to output the audio signal;
an air pressure regulator comprising a fluid tube connecting an external space of a housing of the audio apparatus to an internal space of the housing, the air pressure regulator being configured to adjust a change in an air pressure of the internal space of the housing, the fluid tube extending from the external space of the housing into the internal space of the housing, a portion of the fluid tube being fixed inside the housing; and
an audio signal processor configured to:
generate an anti-noise signal by using the ambient sound acquired by the at least one microphone, the anti-noise signal being a signal that cancels noise in the ambient sound, and
output the anti-noise signal and the audio signal through the speaker,
wherein the air pressure regulator further comprises a porous member disposed in the fluid tube, the porous member being configured to suppress a flow of air flowing through the fluid tube between the external space of the housing and the internal space of the housing, and
wherein a location of the porous member disposed in the fluid tube is adjustable.
