  • Patent number: 10145290
    Abstract: A mount (100) for an exhaust system includes a support (110) configured for being fixed to a component of the exhaust system (200) or an underbody of a vehicle, and a mounting mandrel supported by the support (110). The support (110) has a first plate (111) and a second plate (112) spaced apart from the first plate (111). The first plate (111) and the second plate (112) each include a fixing section (113, 114) for fixing the support (110) to a component of the exhaust system (200) or an underbody of a vehicle. The first plate (111) and the second plate (112) each includes an opening (115, 116). The mounting mandrel (120) includes a first section (121) configured for penetrating through an exhaust system rubber (300). The mounting mandrel (120) has a second section (122) that passes through the openings (115, 116) in the first and second plates (111, 112).

  • Patent number: 9066168
    Abstract: A sound generator 103 for an anti-noise system for influencing sound waves propagating in exhaust systems or intake systems of vehicles driven by an internal combustion engine includes a loudspeaker basket 123, a membrane 122 supported by the loudspeaker basket 123, a permanent magnet 121 supported by the loudspeaker basket 123, a voice coil 126 supported by a voice coil carrier 125 and a membrane stop 150. The voice coil 126 is located within a constant magnetic field generated by the permanent magnet 121. The voice coil carrier 125 is supported by the membrane 122. The membrane stop 150 is located on the loudspeaker basket 123 adjacent to the membrane 122. The membrane stop 150 includes a projection 151 extending towards the membrane 122. An anti-noise system using the sound generator and a vehicle using the anti-noise system are also provided.
