Variable Sound Muffler System

摘要

A muffler system includes a housing having two pipes perforated with holes or other shapes that slide or rotate on top of each other. The sliding or rotating pipes allow for varying degrees of alignment of the holes and thereby allow more or less sound dampening. The control of the sound dampening is actuated by an operator via an electric switch that activates at least one of the pipes inside the muffler system to rotate or slide on each other thereby aligning the holes.
