3D Educational Sound Board
Hattung Say House is the world’s first foldable 3D educational sound board—an innovation that transforms conventional learning posters into an immersive and interactive experience.
Protected by a global patent, this product redefines educational tools by merging auditory, visual, and tactile engagement into one compact, child-friendly format.
Unlike traditional flat paper posters, the 3D structure incorporates ten essential early learning themes in a unified, foldable board. Its design allows it to be easily set up during play and stored neatly afterward, making it particularly suitable for modern families living in compact spaces.

The interactive Hattung Pen activates spoken words and realistic sound effects—such as animal calls, musical instruments, and vehicle noises—when it touches the board. This multisensory approach holds children’s attention and encourages repeat engagement by stimulating their auditory curiosity and imagination.
It creates a learning environment that is both intuitive and playful, keeping children engaged as they explore new concepts at their own pace.
Additional features include a safe, built-in mirror that supports emotional development by helping children recognize and interpret facial expressions. The magnetic board surface offers creative freedom for kids to use magnetic accessories or draw freely, enabling hands-on exploration that reinforces cognitive and motor skills.
These elements make Hattung Say House more than a learning tool—it becomes a hub for storytelling, sensory play, and emotional expression.

Every aspect of the product prioritizes child safety and durability. The frame features rounded edges, and the hand-sewn fabric exterior adds both softness and resilience. It meets rigorous international safety standards, including KC (Korea), CE (Europe), and CPC (U.S.), ensuring peace of mind for parents and educators alike.
Currently exported to the United States, Mongolia, and Vietnam, the product has been praised for its innovation and usability in diverse educational settings.
Thanks to Chum Education’s in-house capabilities—from planning and production to marketing and logistics—Hattung Say House can be rapidly localized. It is now available in five languages: Korean, English, Vietnamese, Mongolian, and Chinese, with support for more languages upon request.
As an all-in-one educational and developmental toy, Hattung Say House is poised to become a global leader in early childhood learning.
