Speakerless-Audio Concert

Get the best sound – even with­out speak­ers

Thanks to a speaker-less sound system, Continental has reinvented car audio systems, drastically cutting down on weight and installation volume in the process. Compared with conventional high-end 3D sound audio systems, the speaker-free system requires 95% less volume. 

Equipped with actuators that cause specific surfaces in the vehicle to vibrate, the system works in a similar way to stringed instruments and provides a high-end audio experience for every vehicle class.

In order to achieve first-class sound, conventional high-end audio systems in vehicles often require 10, 20 or even more speakers. These systems usually weigh up to 40 kilograms and have a total installation volume of 10 to 30 liters. However, modern vehicle architectures and interior concepts require ever more efficient, lighter and space-saving solutions in order to improve the user experience of the vehicle occupants in the long term. For this reason, Continental has developed a speakerless audio concept that delivers excellent concert hall-like acoustics with significantly lower weight and installation volume. At the same time, it contributes to lower CO2 emissions worldwide. 

With Ac2ated Sound x AMBEO Mobility, the two companies Continental and Sennheiser offer a first-class 3D audio experience with a scalable and adaptive sound system that completely dispenses with conventional speakers. Ac2ated Sound induces vibrations in existing surfaces in the vehicle, eliminating the need for conventional speakers. Together with Sennheiser’s integrated 3D audio algorithm, the sound concept delivers reproduction of music and speech which immerses the vehicle occupants in a lifelike sound world. Compared with conventional audio systems, Ac2ated Sound saves up to 90 percent of the weight and space required.

As a result, the system not only delivers the highest audio quality, but is particularly suitable for electric vehicles, where weight and space are at a premium. At CLEPA Innovation Award 2021, the technology company’s partnership with Sennheiser placed 3rd in the “Cooperation” category.
