[Digital Audio-Visual Network News] Recently, at CES (International Consumer Electronics Show) in 2020, Continental Group (parts supplier) and Sennheiser (Sound Expert) jointly launched "Car Speakerless Audio System". This system allows immersive sound effects throughout the car. It is reported that the system is integrated by Sennheiser's patented AMBEO 3D audio technology and Continental's Ac2ated Sound audio system. It uses the surface of the interior trim panel as a vibration sound source to emit sound, which is very different from traditional speaker technology.
1. Lighter and smaller Ac2ated Sound sound system
Compared with traditional systems, Continental's Ac2ated Sound system reduces weight and footprint by up to 90%. This system not only generates high-quality sound effects, it is also very suitable for electric vehicles that save space and weight. Invisible audio technology gives car designers and manufacturers the freedom to do more design for the interior of the car, because they don't need to think about reserving space for large speakers.
2. AMBEO 3D audio technology without specific sound source
Sennheiser's AMBEO 3D audio technology does not require a specific 3D sound source, and the spatialization algorithm can turn any stereo music into an immersive experience. The interior surface of the car can vibrate like a speaker diaphragm. The exciter can vibrate the A-pillar trim, door trim, roof lining, rear shelf and other components, so as to emit sound in different frequency bands.
3. System Introduction
The system is inspired by classical stringed instrument technology. The simulated stringed instrument uses a wooden body as the resonance cavity. It uses a specially developed exciter to vibrate a specific surface in the car to bring a natural sound experience to the driver. At the same time, the system intelligently analyzes the sound content, and the patented algorithm can artistically remix the sound to create an emotional experience.
