RESONATOR AND SOUNDPROOF PANEL USING THE SAME

摘要

PURPOSE: A resonator and a soundproof panel using the same are provided to make efficient sound absorption structure. CONSTITUTION: A soundproof panel comprises a main body(110), a front open part(120) and rear open part. The main body forms a resonance space(111) in inside. The front open part is formed in front of the main body in order to pass through the resonance space. The rear open part is formed behind the main body in order to pass through the resonance space. The width of the front open part is smaller than rear open part.
