Good sound in a car requires a lot of space and adds extra weight to the car due to the use of voice coils, magnets, etc. And modern cars can have more than 20 speakers of different sizes. LG Display, together with an unnamed company, worked on this issue and found a solution.

The proposed technology is called the Thin Actuator Sound Solution and is a small panel measuring 150×90 mm (5.9×3.5 inches), only 2.5 mm (0.1 inches) thick and weighing only 40 grams (1.4 ounces), which can replace traditional speakers.

A similar technology has already been used in LG and Sony TVs, where sound could be obtained thanks to panels that resonate. In the same way, the sound is generated here thanks to the vibration of the displays and various materials inside the car, which, according to LG Display, provides “rich three-dimensional sound with immersion.”

Such devices can be installed in the dashboard, ceiling and even headrests.

The commercial version of the Thin Actuator Sound Solution is scheduled to be completed in the middle of next year, and prototypes will be heard at CES 2023 in January.
