Latest Patents

One of Kobayashi's latest patents is an engine sound processing system. This system utilizes microphones positioned at the air inlet of the engine and the vehicle cabin's side wall surface. It captures engine sounds, which are then processed by a signal processing section. The processed engine sound is output through a speaker located in the vehicle cabin. The signal processing section includes a filter that simulates the sound insulation characteristics of the vehicle cabin. Additionally, a transformation section processes the engine sound based on driving conditions. The spectrum transformation characteristic is determined by values detected from various sensors, enhancing the overall engine sound experience.

Another significant patent involves a floor structure and floor base panel. In this design, a solid area is formed on the support board of the vibration-proof support leg, while multiple cavities extending parallel to the floor surface are created in other areas. This innovative structure allows vibration energy from impacts to be reflected at the boundary between the solid area and the cavity formation area. As a result, the vibration and sound energy transmitted to the slab is significantly reduced.
