LG Display Develops Car Speaker 'Invisible' at Passport Size and Coin Thickness

Install Anywhere in the Car... Consistent Sound Quality
Wider Cabin Space and Innovative Design

[Asia Economy Reporter Moon Chaeseok] LG Display has opened the era of 'Invisible Speakers' in automobiles.

On the 21st, LG Display announced that it has developed a 'vehicle sound solution' equipped with this function. The company plans to commercialize the product for the first time in the industry in the first half of next year.

The product is characterized by being smaller and lighter than existing speakers. LG Display's independently developed film-type exciter (vibration generating device) uses the panel or various vehicle interior materials as a diaphragm to produce sound.

It is as small, thin, and light as the size and weight of a passport (150mm×90mm - 40g) and the thickness similar to a 500-won coin (2.5mm). It is explained that the weight is about 30% and the thickness about 10% compared to existing car speakers. When installed in a car, the speaker is invisible to passengers. This greatly increases the freedom of interior design. It also drastically reduces the space occupied by conventional speakers, allowing for more spacious passenger areas.

It is designed to be installed not only on vehicle displays but also in various places where it was previously difficult to install speakers, such as the ceiling, pillars, dashboard, and headrests. This ensures no sound quality variation regardless of seating position and achieves a high spatial sound effect, providing richer sound. An LG Display official stated, "We have received evaluations from global acoustic verification institutions that the sound uniformity by seat position is superior to existing mass-produced vehicles, and the clarity and tone of the sound are at a premium level."

Additionally, reducing the speaker's weight contributes to carbon emission reduction and energy efficiency improvement. It also shows an 'eco-friendly' aspect by not using rare earth materials such as neodymium (Nd), which are essential in conventional speakers.

The product was recognized for innovation in ▲space creation ▲design ▲sound quality ▲environmental friendliness, and recently received the Innovation Award in the 'In Vehicle Entertainment & Safety' category at the International Consumer Electronics Show (CES), the world's largest IT and home appliance exhibition, from the Consumer Technology Association (CTA) in the United States.

LG Display plans to unveil the 'vehicle sound solution' developed in collaboration with a global audio company for the first time at CES 2023, which opens on January 5 of the following year. Yeo Junho, Executive Director of Business Development at LG Display, said, "We plan to innovate the existing large and heavy speakers in terms of space, design, and eco-friendliness to realize 'high-quality' sound and provide customers with a new experience never before."
