Latest Patents

Johnson holds a patent for a "Debris blower with sound attenuation resonator." This invention features a blower apparatus that includes a fan and motor generating airflow from an inlet end to an outlet end. The airflow defines an airflow axis and a cross-sectional plane normal to this axis. An enclosure provides a path for the airflow towards the outlet end, while a resonant chamber is located near the airflow entrance end of the enclosure. This resonant chamber consists of first and second sections that encompass corresponding first and second volumes of different sizes, which are selected to form an acoustic resonator. The acoustic resonator effectively attenuates noise from the blower over a selected attenuation frequency range. Johnson's innovative design enhances the user experience by minimizing disruptive sounds.
