Ac2ated Sound: The Car is the HiFi

The New York Times: “Continental, a German auto-components supplier, has developed technology that makes parts of the car’s interior vibrate to create high-fidelity audio on a par with any premium sound system on the road now. The approach turns the rear window into a subwoofer. The windshield, floor, dashboard and seat frames produce the midrange. And the A-pillars — the posts between the windshield and the doors — become your tweeters, said Dominik Haefele, the leader of the team that developed the technology.” He comments: “It’s a 3-D immersive sound, and you’re experiencing the music in a very different way. You’re in the sound. You feel it all around you, like you’re adding another dimension to it.”

“The key components are transducers — small devices that use a magnet wrapped in a copper coil to convert electrical energy into mechanical energy. Run current through the wires, and the transducer vibrates. Continental has figured out a way to implant transducers in a car’s interior and use them to turn interior panels into speakers.”

“The system, which Continental calls Ac2ated Sound, should begin appearing by 2021, Mr. Haefele said. He declined to name the carmakers that will offer it, although Mercedes, BMW and Audi are all big customers — and frequent adopters — of Continental’s technology.”
