Claim:
1. A personal audio equipment provided with an air vent unit and a noise cancellation function and configured to be inserted in a user's earhole or be used hung around a user's ear, comprising: a donut-shaped sound regeneration unit; an electric wire unit which is able to transfer an electric signal to the sound regeneration unit; and a speaker cover unit in which the sound regeneration unit is installed inserted, wherein an air vent unit is provided at a central portion of the speaker cover unit, and when the personal audio equipment is before operating after a user has worn, an external sound or noise ( wherein in case of a user who uses the personal audio equipment being inserted in his earhole, an external sound or noise is easily transferred to cochlear ducts via the air vent unit when not in use, and air ventilation is carried out, so the earhole is dried, and a noise cancellation unit, for emitting waveforms which will be offset with a corresponding soundwave in such a way to detect and analyze the waveform of external sound so as to cancel the external sound transferred via the air vent unit, is provided inside of the air vent unit, by means of which in case where the user is on the phone or is listening to the music using the audio equipment, the noise, mixed sound or external sound being transferred to the cochlear ducts via the air vent unit is blocked, and the sound from the audio equipment is intensively transferred to the cochlear ducts in such a way that the noise transferred via the air vent unit is detected, and an opposing wave is emitted, thus offsetting the noise.
