Abstract
A headphone having a waveguider is disclosed which can control the amount of air flowing into the headphone. The headphone includes: a housing having a receiving space therein and at least one or more air inlets at one side thereof, in which the housing is opened at the front side thereof a speaker placed in the receiving space, for generating audio sounds according to input electrical signals; a cover for closing the front side of the housing, the cover forming a plurality of audio sound through-holes through which the audio sounds from the speaker pass; and a waveguider slidably and rotatably installed to the housing. The waveguider includes a kernel part protrudently formed, for guiding the audio sounds passing through the cover to the inner ear, and an opening/closing part for closing at least one or more air inlets according to a rotation angle thereof to control the amount of air that instantly flows into the housing. The waveguider is slidably and rotatably moved to partially or completely close a plurality of air inlets formed in the housing. Therefore, the amount of air flowing into the housing can be controlled and thus the intensity of the bass can be adjusted.
