There’s no need for a traditional woofer and tweeter in a new type of sound system developed by major car supplier, Continental.
Instead, the system uses the car’s headliners, A-pillars and other parts to act as vibrating “speakers.”
Continental says it is “reinventing the car audio system” by replacing conventional loudspeakers with actuators that create sound by vibrating certain surfaces in the car.
Where some car companies are adding 10 to 30 speaker sound systems, Continental’s approach is in direct opposition. It’s actuators use a magnet and coil to oscillate car surfaces instead of a cone.
Certain areas of the car are suited to producing certain frequencies. The A-pillar can generate high frequencies and the door panels generate mid range frequencies while the roof lining or rear shelf can produce bass.
Continental said, “conventional high-end car audio systems can easily require between ten and 20 or more speakers. Owed to the design of a conventional speaker this gives the system a weight of at least up to 15 kilograms [33 lbs] with a total box volume of ten to 30 liters. Continental’s speaker-less audio system can weigh as little as 1 kilogram [2 lbs] and requires as little as 1 liter of total box volume.”
Continental claims the system produces a more natural 3D sound experience.
