Audio without speakers and naked-eye 3D display without glasses, CES Continental's booth is really good at it

Headphone enthusiasts have been known to "boil their headphones," which roughly translates to keeping the sound quality stable by regularly increasing the amount of time the diaphragm in the headphones is in motion. But I'm afraid the speaker-less 3D immersive sound system unveiled by Continental at CES, as the name suggests, is a sound system without speakers.

No speakers? What does that rely on to pronounce sound? As you know, sound is generated by the principle of vibration, so since there is no more speaker, then this car without speakers 3D immersive sound system is actually relying on the vehicle's internal surface vibration for sound. It is a new technology developed by Continental United to Sennheiser using its patented AMBEO?3D audio technology integrated with Continental's own Ac2ated?Sound audio system, which achieves the effect of abandoning the traditional speaker technology and utilizing vibrations on the surface of the vehicle to produce sound.

And the sound produced by this audio system is more three-dimensional than that of any ordinary stereo because it is generated by vibrations on the surface of the vehicle's three-dimensional interior space. The specific principle of realizing this technology is also inspired by the technology of classical stringed instruments, and the new sound system simulates the characteristics of stringed instruments with wooden bodies as the ****ing chamber.

Continental and Sennheiser made specific surfaces in the car vibrate using a specially developed exciter that vibrates components such as the A-pillar trim, door trim, roof liner, rear shelf and more to emit sounds in different frequency bands for a very natural sound experience. According to Autolab's on-site experience, the exciter doesn't affect the sound of the vehicle's interior because someone is touching or relying on it, and touching the pronouncer panel with your hand doesn't have any effect on the sound, which may be due to the frequency and amplitude of the exciter.

And the weight and size of this sound solution is dramatically reduced compared to conventional speaker systems. A typical in-vehicle conventional sound system has a lot of components and can weigh up to about 40 kilograms. And Continental came up with a speaker-less 3D immersive sound system that utilizes existing surfaces to produce sound, eliminating the need to think about reserving valuable space for large traditional in-car speakers, and reducing the amount of space taken up in the car by 75% to 90%.

Continental also has an interesting technology at its CES booth this year - naked eye 3D display. Fully known as 3D light field display technology center console, no need to wear special glasses to experience a 3D display effect that incorporates tactile interaction. In other words, you can not only experience the 3D display effect without 3D glasses, and 3D display screen also supports touch control, awesome.

The best application scenario for this key element of human-computer interaction is the cockpit center console, where touch control and 3D display are all available, and the viewing angle is not limited to the main driver, so that all members of the car can enjoy the 3D experience without wearing special glasses or head-mounted tracking cameras. This three-dimensional, bright display, image enhancement and sophisticated lighting effects also make it easier and safer to communicate essential information while driving.

Continental is also currently working with partner Leia to integrate this technology into the center console display, with the promise of a 4K-resolution version and haptic feedback capabilities. How? This technology is similar to the viewpoint tracking + information feedback + plane mapping display system that BMW demonstrated at this year's CES, utilizing a smart cockpit, which is a cool piece of black technology once it's in mass production.
