‘Invisible speaker’ -Thin Actuator Sound Solution system

The new speakers come in a passport-like size (150mm x 90mm) that measures just 2.5mm thick, or the equivalent of two coins stacked together, and weighs in at a svelte 40g. This makes it just 70% lighter and 90% thinner than a conventional car speaker.

It leverages film-type exciter technology. It works by vibrating off display panels and various materials inside the car body to produce rich, 3D immersive sound experiences.

These LG vibrating speakers turn car dashboards and headrests into speakers

LG’s new ‘invisible’ speakers could revolutionize car audio

The slim design means the speakers could be situated almost anywhere within the interior of a vehicle, with the tech giant suggesting they could be hidden inside headliners and pillars, as well as headrests and dashboards.

While conventional speakers are large and heavy due to components such as the voice coil, cone, and magnet, the Thin Actuator Sound Solution is extremely thin and lightweight thanks to LG Display’s film-type exciter technology. The company’s unique technology allows the device to vibrate off display panels and various materials inside the car body to enable a rich, 3D immersive sound experience.

In addition, LG Display has excluded the use of rare earth elements such as neodymium (Nd) normally used in conventional speakers, boosting the speaker’s eco-friendly factor.
