Continental Ac2ated Sound

A disruptive solution for your premium sound system.

So, how does “Nothing” sound? It isn’t anything you ever may have heard of – it’s something completely new. It’s inconspicuous, it can’t be seen ... it's not even a speaker! It's not what you might expect – nevertheless: a true premium sound experience.
Ac2ated Sound replaces loudspeakers with exciters that are directly mounted to the vehicles interior or exterior panels and creates structure-borne sound.

Ac2ated Sound

Continental’s innovative concept abandons conventional speaker technology altogether, exciting select surfaces in the vehicle interior to produce sound. Combined with Sennheiser’s AMBEO Mobility, the concept achieves a breathtaking 3D sound reproduction that envelops passengers in an incredibly detailed and vivid soundscape and lets them enjoy their in-car entertainment to the fullest.

Ac2ated Sound - How it works

Inspired by the technology of classical string instruments, which use their wooden body as a resonance chamber, specially developed actuators excite specific surfaces in the vehicle interior. The result is an extremely natural sound experience for the occupants, who feel as if they are sitting in a concert hall surrounded by sound.

With Ac2ated Sound, many components are unnecessary because the surfaces in the vehicle vibrate just like speaker diaphragms. Actuators cause components such as the A-pillar trim, door trim, roof lining and rear shelf to vibrate so that they emit sound in different frequency ranges.



The System Advantages

Ac2ated Sound provides several advantages compared to a conventional speaker system. The design and weight of the actuators are much smaller than conventional speakers, without compromising the sound experience.


A2S_Benefits.pngIn comparison with conventional speaker systems, the audio solution has a much lower weight and significantly reduced box volume. With a multitude of components, conventional audio systems weigh up to 40 kilograms (more than 88 pounds). By using already existing surfaces, Ac2ated Sound is distinctly more efficient in saving space. It achieves a reduction between 75 and 90 percent in contrast to existing conventional systems on the market.

At the same time, the invisible audio technology gives vehicle designers and manufacturers the freedom to do more with an automobile’s interior, as they no longer need to account for large speaker faces taking up valuable space.
