Innovations in technology are changing how cars are being designed, from Car Seat Covers to the engine, the modern car is vastly different from the its predecessors. What was once considered necessities in the past, like CD players, have become a removable option. On top of all of that, automotive manufacturers are looking for ways to build lighter cars, with many getting rid of the spare tire, and, recently, Mazda said it’ll be replacing the lead-based starter battery on some of their models with a lighter, smaller lithium-ion iteration.
Whilst Car Seat Covers won’t be going away soon, car speakers might just be next to fade, if global automotive supplier Continental’s latest development. The company’s working on a new audio system that don’t utilize traditional speakers, instead relying on compact actuators, which behave similarly to the cores of their more traditional predecessors.
The new system will provide the deep bass, rich midrange and melodic highs that people crave from their music, only emanating from the car. Continental tested the system by installing it on a late model Mercedes Benz C-Class, claiming that the new system delivers quality audio to even the most discerning ears. Dubbed ‘Ac2ated Sound’, which behave like transducers, generating audio by vibrating surfaces in the interior of the car, and Continental says that it can be integrated into any vehicle.
The system would provide lower weight and power consumption when compared to the traditional high-end vehicle audio system, on top of providing volumes higher by at least a factor of ten. The system doesn’t need any additional installations, as the system’s needed materials are already found in the car itself.
The system’s actuators are made up of a magnet and a coil, which create micro-vibrations that excite the vehicle’s interior to produce audio. According to Continental’s engineers, specific areas in the car can each cover the required three main frequency ranges for any audio system. For example, the A-pillar works well for high frequencies, whilst the door panel works well for medium frequencies, whilst the traditional position for speakers; the rear shelf, work well for the low frequencies needed for bass.
This new system could weigh as little as a kilo and need about a liter of box volume, key considerations for automakers looking to cut down on the weight of interior components.
