Latest Patents

Takemori holds a patent for an electronically controlled active exhaust-noise attenuation muffler. This invention comprises a loudspeaker that serves as a secondary sound source, which is strategically arranged upstream of a tailpipe. The muffler works by emitting a secondary sound that is in opposite phase to the exhaust noise, effectively reducing the noise level produced by the exhaust system. The design includes a flared-out tailpipe that gradually increases in cross-sectional area towards the downstream end, which helps to minimize pressure loss in the exhaust gas flow. Additionally, the tailpipe section is engineered to attenuate high-frequency noise components propagated with the moving stream of exhaust gases.
