SOUND GENERATOR ON AN AIR INTAKE PATH FOR ABSORBING AND REDUCING UNPLEASANT HIGH-FREQUENCY SOUND FROM A MEMBRANE

摘要

PURPOSE: A sound generator on an air intake path is provided to replace a proper tuning cap when tuning the sound quality and tone of the sound generator since a variety of kinds of tuning caps having a variety of lengths of pressure control protrusions are supplied. ;CONSTITUTION: A sound generator on an air intake path comprises a membrane and a pressure control unit. The membrane is interposed between a lower cap and an upper cap. The membrane receives and vibrates the dynamic pressure of inflow air to generate sound. The pressure control unit presses the membrane and comprises a tuning cap with a variety of lengths of pressure control protrusions. The sound generator further comprises a high-frequency sound attenuating unit, which absorbs and attenuates high-frequency sound. The high-frequency sound attenuating unit includes a sound-absorbing form.;COPYRIGHT KIPO 2011
