(16) It should be understood that the appended drawings are not necessarily to scale, presenting a somewhat simplified representation of various preferred features illustrative of the basic principles of the invention. The specific design features of the present invention as disclosed herein, including, for example, specific dimensions, orientations, locations, and shapes will be determined in part by the particular intended application and use environment.

DETAILED DESCRIPTION OF THE INVENTION

(18) The preferred embodiments of the present invention will be described with reference to the accompanying drawings.

(19) The present invention is directed to a personal audio equipment provided with an air vent unit and a noise cancellation function which may include, but is not limited, an audio equipment cover, a sound regeneration unit and an electric wire unit which are the components of a conventional personal audio equipment. In addition to that, the present invention may include, but is not limited to, a sound regeneration unit 11 which is transformed a little to form an air vent unit which is able to partially open a part of an earhole, a speaker cover unit 10, an air vent unit 16, a noise cancellation unit 17, and a sound wave detection sensor (not illustrated).

(20) More specifically, an electric wire unit 15 is provided, which is able to transfer an electric signal to a sound regeneration unit. The air vent unit 16 is formed passing through the central portions of the speaker cover unit 10 and the sound regeneration unit 11. Different from a conventional personal audio equipment wherein the sound regeneration unit is provided at a central portion, and the speaker cove unit is covering the same, as illustrated in FIG. 3, the central portions of the sound regeneration unit 11, the speaker cover unit 10 and the speaker earhole insertion unit 12 are being passed through in a donut shape. Since the central portion of the sound regeneration unit 11 is being passed through in a donut shape, and the speaker earhole insertion unit 12 equips with the air vent unit 16 the central portion of which is being passed through, thus forming a pore for the sake of sound transfer. The pore is provided to transfer sound generated by the sound regeneration unit 11. The sound may be transferred to the cochlear ducts via the speaker earhole insertion unit sound transfer unit 13. Moreover, the earhole insertion unit equips with an engaging unit 14 for the sake of an effective engagement with the speaker cover unit 10.

(21) The air vent unit 16 is provided, which is passing through a central portion of the earhole insertion type audio equipment, and the noise cancellation unit 17 is provided inside of the air vent unit. In case of the user who is wearing the personal audio equipment in the earhole, the user can easily recognize external sound or any noise 20 when it is not operating, and since air can ventilate via the air vent unit 16, any water or moisture can be discharged via the earhole. When in use, a noise cancellation function will be activated so as to emit waveforms which will be offset with a corresponding soundwave in such a way to detect and analyze the waveform of external sound, by which the external sound transferred via the air vent unit can be cancelled, so the sound from the audio equipment can be intensively transferred toward the cochlear ducts.

(22) The present invention equips with a soundwave detection sensor (not illustrated) which is able to detect any soundwave of a horn sound or an alarming sound that the user should pay attention to while the user is on the phone or is listening to the music using the personal audio equipment. The soundwave that the user should pay attention to is detected, and the noise cancellation function is temporarily interrupted, by means of which the soundwave that the user should pay attention to can be transferred to the user via the air vent unit, thus preventing any accident in advance.

(23) The present invention is directed to a personal audio equipment provided with an air vent unit and a noise cancellation function and can be employed to all kinds of audio equipment, for example, a hearing aid, an earphone, a headphone, etc. which is used inserted in the user's earhole or is used covering the user's earhole.

(24) Moreover, since the components of the soundwave detection sensor and the noise cancellation unit, the operation methods thereof and the method for controlling the operation of the noise cancellation unit using the soundwave detection sensor may be obviously drawn from the known technologies, the descriptions thereon will be omitted.

(25) The invention has been described in detail with reference to preferred embodiments thereof. However, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
