  • Patent number: 5218175
    Abstract: A vehicle loudspeaker system includes a vehicle body having inside surfaces enclosing a passenger compartment. At least one elongated conduit has a proximal portion and a distal portion. A loudspeaker driver is disposed in the vehicle body outside the passenger compartment. The loudspeaker driver has a vibratile surface for generating sound pressure waves in response to electrical stimulation. The proximal portion of the elongated conduit is open to one side of the vibratile surface. The distal portion is open to the passenger compartment. The elongated conduit extends from the vibratile surface into the passenger compartment with an effective length corresponding substantially to a quarter wavelength at the lowest frequency of sound pressure waves to be transmitted between the vibratile surface and the passenger compartment. The loudspeaker driver is characterized by moving mass and an unloaded natural resonant frequency at a first bass frequency.
