At CES 2020, currently underway in Las Vegas, Speakerless 3D immersive audio system by Continental and Sennheiser have announced Continental's Ac2ated Sound, which provides speakerless immersive in-vehicle sound.
Sennheiser's patented Ambeo 3D audio technology is being integrated with Continental's Ac2ated Sound system. Continental's 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 3D sound reproduction that envelops passengers in a detailed and vivid soundscape, says the firms.
The system reduces weight and space by up to 90% in comparison to conventional systems, which makes it perfectly suited for electric vehicles, where saving space and weight is a high priority.
"By integrating AMBEO Mobility with Continental's Ac2ated Sound system, the in-car sound experience becomes completely immersive and natural, opening new audio perspectives and realities," says Dr. Andreas Sennheiser, co-CEO of Sennheiser.
"For Ac2ated Sound we have brought together the highest levels of expertise in the areas of acoustics, infotainment and vehicle design," adds Helmut Matschi, member of the Executive Board and Head of the business area Vehicle Networking and Information at Continental. "In Sennheiser, we have found an audio expert who helped us make our pioneering audio system even better. "Together, we have developed an audio system that creates premium sound out of nowhere. Additionally, Ac2ated Sound reduces space and weight. At Continental, we call this sustainability that's music to your ears."
"We are delighted to bring our audio expertise and Ambeo Mobility software into the pioneering Ac2ated Sound system from Continental, calibrating and fine-tuning the sound quality to deliver a completely immersive and natural sound experience that opens new audio perspectives and realities," adds Dr. Sennheiser.
Co-CEO Daniel Sennheiser adds: "Our Ambeo immersive audio solutions deliver the ultimate quality in sound capture, processing and playback. Crucially, the ability to enjoy breathtaking immersive sound does not require specific 3D audio sources - Ambeo Mobility's spatialization algorithm can turn any stereo material into an immersive experience. By intelligently analyzing the content, the patented algorithm artistically remixes the sound to provide an emotional experience, transporting the listener into the music."
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 a natural sound experience for the occupants, who feel as if they are sitting in a concert hall surrounded by sound, says Sennheiser.
Meanwhile, 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. 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.
Continental and Sennheiser are presenting the futuristic audio system in a private exhibit at CES 2020, in the Renaissance Hotel.
