Ac2ated Sound: Immersive Audio System without Speakers

• Continental uses interior surfaces to generate sound
• System enables weight and installation space reduction of up to 90 percent
• New placement options of the sound sources enable a novel sound experience and sound zones
• World premiere: Continental presents exterior sound with actuators for improved safety and sporty sound experience

Ac2ated Sound is the name of the innovative audio system that produces sounds without conventional speakers. Instead, specially developed actuators cause certain surfaces of the vehicle interior to vibrate: for example, A-pillar panels, head restraints, door panels or the rear shelf. In combination with special audio software, this produces an immersive and three-dimensional sound. The speakerless sound system is inspired by classical stringed instruments, with the wooden body acting as a resonance body. Because the new Ac2ated Sound audio technology no longer requires loudspeakers, up to 90 percent of the installation space and weight of conventional audio systems can be saved. This reduces energy consumption and thus CO₂ emissions. At the same time, this opens up new freedom for interior designers. In addition, the actuators can be placed in areas where conventional loudspeakers are difficult to accommodate, e.g., in the headliner or in the headrest. This is essential for creating sound zones and an immersive sound experience.
