<p>PURPOSE: A booming sound generation reducer is provided to generate booming sound by installing an unbalance driving gear to an input shaft connected to a motor. CONSTITUTION: An input gear(440) is combined with an input shaft. An output gear is gear-combined with the input gear. An unbalance driving gear(300) is formed at the input shaft having a predetermined interval with the input gear. An unbalance driven gear(200) is gear-combined with the unbalance driving gear. An unbalance module(100) is connected to the unbalance driven gear. The unbalance module comprises an unbalance shaft, unbalance mass, and a bearing. The unbalance shaft is connected with the unbalance driven gear. The unbalance mass is attached to one side of the unbalance shaft. The bearing supports the unbalance shaft.</p> |
