According to the present invention, an anti-heat damage structure of an ANC apparatus having a speaker installed in the housing thereof has a guide member coupled to the outer circumferential surface of the housing. The guide member has an inlet part formed on one side thereof and opened to receive outdoor air, and has an outlet part formed on the other side thereof and discharging the outdoor air flowing into the inlet part. The housing has outlet holes punched therein and positioned between the inlet part and the outlet part. The anti-heat damage structure is capable of cooling the ANC apparatus using the driving wind of a vehicle without an extra cooling unit, thereby preventing heat damage to the speaker. In addition, the guide member adjacent to and arranged below the speaker is capable of functioning as a speaker enclosure because the housing has the outlet holes punched therein, thereby improving the output of a low-frequency sound and increasing the tuning range of an exhaust sound. |
