摘要
The present invention relates to a multi-link type opposite phase sound generating device and an exhaust discharge sound reduction structure and, more particularly, to a multi-link type opposite phase sound generating device and an exhaust discharge sound reduction structure capable of reducing an exhaust discharge sound by offsetting noise of two input waves having the opposite phases to each other as the device branches the exhaust discharge sound into a pair of exhaust pipes, outputs a frequency of the exhaust discharge sound by converting it into the opposite phase by applying the opposite phase sound generating device to one of the exhaust pipes, and combines it with the exhaust discharge sound going through the other pipe.
