The cross-sectional area of conduit 7 passage is less than 1/10th of the cross-sectional area of described first acoustic conducting pipe 5 passage, if described first sound
The cross-sectional area of conduit 5 passage is fixed, then the cross-sectional area of described second acoustic conducting pipe 7 passage has maximum.When described first sound
When in the passage of conduit 5, flow is larger, only less second acoustic conducting pipe 7 of one channel cross-sectional area of setting can not reach requirement
Soundproof effect.Therefore, it can arrange multiple noise elimination structures with same resonance frequency to obtain preferable soundproof effect.
