Abstract: A system for controlling an interior sound of a vehicle phase-changes the frequency of additional sound based on the engine operating state to increase the current density, thereby inhibiting signal distortion by increasing the current density. As a result, the distortion phenomenon caused by excessive use of amplifier current when generating the additional sound is reduced or minimized, and unnecessary noise is inhibited from occurring in a vibration generator and a frame of the vehicle.

Abstract: An air cleaner may include a filter case configured to introduce, by a suction force of an internal space, ambient air being discharged through a filter provided in the internal space as intake air from which foreign substances are removed; and a built-in valve built in the internal space of the filter case and configured to form an ambient air introduction path for introducing the ambient air and an additional ambient air introduction path separated from the ambient air introduction path and to open the additional ambient air introduction path so that the ambient air flows into through the additional ambient air introduction path when the suction force is increased.

Abstract: An air cleaner assembly includes an air cleaner body into which air flows from outside, an air cleaner cover which is fastened to the air cleaner body and from which the filtered air is exhausted, and an air filter installed between the air cleaner body and the air cleaner cover to filter foreign material, and which is installed at an intake pipe introducing air into an engine from outside, where a diffuser guiding the exhaust of the filtered air is installed at the air cleaner cover; and the supporting member, which supports an outside surface of the diffuser on the air cleaner body and the air cleaner cover and allows air to pass in a longitudinal direction of the diffuser, is installed at the air cleaner body and the air cleaner cover, respectively, thereby supporting the diffuser and tuning the intake sound by the air flowing therein.

Abstract: An air cleaner is provided. The air cleaner includes an air cleaner body and air cleaner cover that are coupled to each other to form an internal space for mounting a filter and that are clamped and separated through a cover clamp. The filter purifies air that is introduced through a duct inlet into air which is to be discharged through a hose outlet. A filter fixer is formed in the internal space to seat the filter and forms a filter holding force to block swaying of the filter. Additionally, a filter adapter is mounted into or detached from the internal space and is inserted into the internal space to form a filter fixing force for fixing the filter.
