Innovation by Hyundai Mobis: Movable Sound System for Automotive Interior Design

This technology is part of efforts to create a unique interior design and ensure optimal sound quality in various display scenarios.

Hyundai Mobis is evolving into a specialist for future mobility technologies and is driving innovations in vehicle interior design with a new technology. The car is no longer just a means of transportation but is developing into a multifunctional space where people can relax, entertain, and communicate with each other.

Accordingly, vehicle interior design is changing to not only ensure the safety and comfort of passengers but also to provide a differentiated user experience.

Movable and synchronized

The movable sound system is designed to perfectly synchronize with the rollable display. Hyundai Mobis developed the world's first rollable display two years ago, which moves up and down. This innovative technology features a large 30-inch display that can be adjusted according to driving conditions, providing users with information such as navigation, music, and videos.

When the display is in operation, the speakers installed on the right, left, and in the center of the vehicle's front adjust their angle and move to minimize interference from surrounding sound waves and ensure optimal quality.

The rollable display can be extended to its maximum size, allowing the driver and passengers to enjoy music and videos even in idle or autonomous mode of the vehicle. At this point, the movable sound system is retracted, and the sound is directed toward the vehicle's windshield to avoid sound interference from the fully extended display.

In contrast, during driving, the display enlarges to only one-third of its original size to ensure that the driver's view is not obstructed and only a minimum of driving information is displayed. During this time, the speaker addresses the driver and outputs audio. The position of the speaker is dynamically adjusted to the dimensions of the display to provide the driver and passengers with a more vivid sound quality.

Windshield as Display

Hyundai Mobis has developed this innovative, display-synchronized, movable sound system with the belief that the latest vehicle display features elements such as a large screen, high resolution, and a sleek design to stand out in the field of vehicle interior design. This innovation also reflects Hyundai Mobis's confidence in its technological competence in high-quality vehicle display and sound systems.

Leading Innovation through Integration of New Technologies into Automotive Parts Technology

At this year's CES, Hyundai Mobis unveiled a real vehicle with its Holographic Windshield Transparent Display, which uses the windshield as a display without requiring physical display devices. In addition, the company has a range of the world's first original premium systems for in-vehicle use, including rollable, tiltable, and QL displays.
