Summary:PURPOSE: A muffler using resonance and expansion of sound wave for ventilation is provided to achieve perfect sound reducing effect at a specific frequency. CONSTITUTION: A muffler using resonance and expansion of sound wave for ventilation comprise: a cubical body(1); an inlet pipe(2) which a sound wave and air flow in the inside of the body through; an outlet pipe(3) which the sound wave and the air flow out from the inside of the body through; an inlet partition(4) which divides the internal space of the body; an inside partition(5) which forms the small space of the inside of the body; and an expansion pipe(6) which is installed in the inlet partition and the inside partition. The internal space of the body is classified into a front room(10), an inner room(20), and a side room(30) which are interlinked together by the expansion pipe.
