The conversion module 131 converts the audio signal provided from the reception module 121 into the vibration signal through the control unit 140 and the vibration module 132 vibrates based on the vibration signal provided from the conversion module 131 So that the user can listen to the audio signal provided from the external audio apparatus 10. [ A plurality of vibration modules 132 may be provided. For example, a plurality of vibration modules 132 may be provided on one side of the housing 110 supported on one ear of the user and on the other side of the housing 110 supported on the other ear of the user.

 In addition, the vibration module 132 may be entirely housed in the housing 110, or a part of the vibration module 132 may be exposed to the outside of the housing 110 to be in contact with the user. Therefore, even if the housing 110 is not closely contacted to the user, the user can stably hear the audible audio by the plurality of vibration modules 132. Meanwhile, the vibration output from the vibration output unit 130 allows the audio to be directly transmitted to the cochlea through the skull of the user, so that the audio is transmitted to the brain through the auditory nerve.

On the other hand, the control unit 140 may be provided inside the housing 110 to control the overall function of the headphones 100.
