AI Technical Summary
Existing technologies for in-vehicle sound field zoning control suffer from high system complexity, high cost, poor robustness, and insufficient sound energy contrast, making it difficult to achieve robust sound field zoning control in dynamic environments.
By employing loudspeaker array technology combined with active closed-loop control, the sound field is initially partitioned through the filtering effect of the loudspeaker array, and the stability of the sound field partitioning is enhanced by adaptive control technology. Furthermore, the robustness of the sound field partitioning and the difference in sound volume are enhanced through active closed-loop control.
It achieves robust sound field zoning control in both static and running vehicle conditions, enhances the sound volume differences between different sound field areas, and improves the sound field zoning experience and robustness.
