After revealing the world’s first stretchable high-resolution display recently, South Korea-based electronics giant LG Display on Monday unveiled the Thin Actuator Sound Solution, a new sound technology for automobiles, which could revolutionize vehicle infotainment systems.
While components such as the voice coil, cone, and magnet make the conventional speakers large and heavy, the Thin Actuator Sound Solution, on the other hand, is extremely thin and lightweight due to LG Display’s film-type exciter technology.
This technology allows the device to vibrate off display panels and various materials inside the car body “to enable a rich, 3D immersive sound experience”, claims LG.
The panel speaker comes in a passport-like size (150mm x 90mm) with a thickness of 2.5mm. It weighs just 40g, which makes it 30 percent of the weight and 10 percent of the thickness of a conventional car speaker.
Further, the slim design of the speaker allows the removal of speaker grills, as it can be installed anywhere inside the car such as the dashboard, headliner, pillar, and headrests.
Besides this, it also improves space efficiency by freeing up the space normally occupied by in-car speakers “without compromising sound quality,” according to LG.
In addition, to boost the speaker’s eco-friendly factor, LG Display has also eliminated the use of rare earth elements such as neodymium (Nd), which is generally used in the magnets of conventional speakers.
“We have transformed the conventionally heavy and bulky speaker into a high-quality ‘invisible’ sound solution by using our cutting-edge technology to elevate space, design, and eco-friendly factors and provide a next-level sound experience like none before,” said Yeo Chun-ho, Vice President and Head of the Business Development Division at LG Display.
LG’s new Thin Actuator Sound Solution has received the CES 2023 Innovation Award (‘In-Vehicle Entertainment & Safety’ category) from the Consumer Technology Association in recognition of its space efficiency, design and sound experience innovation, and eco-friendliness.
The company is set to showcase the Thin Actuator Sound Solution, which was jointly developed with a global audio company, at the CES to be held in January 2023. This innovative solution will be commercialized in the first half of 2023.
