"Only the Sound You Need, Where You Need It": Audio Tech Company JD Solutions' "Ultra-Directional Speaker"

Achieving a comfortable listening environment even in settings like apartment buildings where consideration for living noise is required.

Contributing to sales promotion by pinpointing advertising audio to specific areas within a store.

Extensive implementation track record in various facilities, including museums and exhibition halls.

Accident prevention and safety assurance with portable high-power directional speakers: "Clearly transmitted to distant locations."

What is an Ultra-Directional Speaker?

An ultra-directional speaker is an acoustic device developed using the high directivity of ultrasound. Unlike conventional speakers, it can deliver sound only to a specific space by giving sound strong directionality.

Designed so that sound is only audible within a range of approximately 5 to 10 degrees from the installation point, it is possible to create individual listening spaces while suppressing noise interference to the surroundings. Therefore, it is utilized in a wide range of applications.

While directional speakers have been offered by other manufacturers, JD Solutions' ultra-directional speaker achieves world-class ultra-directional sound quality through JD's proprietary patented technology, the ultrasonic modulation algorithm.

It is particularly effective for introducing and explaining specific exhibits in museums and exhibition halls, and also contributes to improving product appeal in supermarkets and convenience stores by delivering promotional audio limited to specific sales floors or product shelves.

In South Korea, its advertising effectiveness was recognized in a demonstration experiment with CU, the country's largest convenience store chain, and it is scheduled to be introduced in 3,000 stores within the year. Furthermore, the company aims to expand to a total of 12,000 stores nationwide in South Korea in the future.

High advertising and guidance effect, active not only indoors but also outdoors.

Guidance broadcast system at pedestrian crossings.

Ultra-directional speakers are widely used not only for advertising purposes in indoor spaces but also outdoors.

They are effective in situations where sound needs to be delivered only to specific areas, such as safety guidance broadcast systems that support safe passage for pedestrians in waiting areas at crosswalks, voice guidance at kiosk terminals, and warning broadcasts in non-smoking areas.

Furthermore, by linking with CCTV and sensors, it is possible to issue real-time warning broadcasts to targeted individuals.

JD Solutions plans to further expand its application areas by continuing to miniaturize ultra-directional speakers and improve their operability.

A speaker that supports public safety beyond commercial use.

JD Solutions also offers the "Portable Emergency Speaker (PES)." This product is characterized by its ability to transmit information clearly and accurately even from a distance of 300 meters.

The inspiration for the development of this speaker came from the "Itaewon crowd crush" that occurred in South Korea in 2022. JD Solutions participated as a panelist in a "Symposium on Preventing Recurrence of the Itaewon Accident" held at the National Assembly of Korea at the time, and began developing products that function effectively even in emergencies, leading to the commercialization of the Portable Emergency Speaker.

In actual accident or disaster situations, evacuation guidance must be carried out in extremely noisy environments, such as the sound of waves or people shouting. In such situations, this product allows commanders and rescue personnel to clearly convey instructions such as "Move up!", "Stop where you are!", and "Wait there!" to targets located far away.

During disasters, information transmission is often difficult due to surrounding noise, leading to an expansion of casualties. The Portable Emergency Speaker is attracting attention as a solution that addresses these challenges and enables swift and accurate evacuation guidance.

In addition, JD Solutions' products are already being used not only in crowded places but also for announcements to prevent drowsy driving in tunnels, and in noisy environments such as power plants and factories. JD Solutions anticipates further utilization in disaster and emergency situations, and at sites where many people gather, such as large-scale events and concert venues.

In Japan, JD Solutions, a South Korean audio tech company attracting attention in the public safety sector beyond personal and commercial use, is introduced and sold by its Japanese partner company, JASP Co., Ltd.
