Application: Display apparatus (Patent ID: US20240098403A1)
The patent filed by LG Display Co Ltd describes a display apparatus that includes a display module with a rear cover and a sound generating module that vibrates the display module to produce sound. The sound generating module is positioned at the rear cover, which covers its rear surface. The electronic apparatus comprises a plate, one or more sound generating modules with vibration devices, supporting frames, and connection members. The supporting frame includes pocket parts to receive the vibration devices, and the rear cover has grooves to accommodate the sound generating modules. The vibration devices consist of base plates, bobbins, magnets, coils, edge frames, and dampers, with options for piezoelectric materials or composites. The apparatus can display images, output sound, or generate sound associated with images, with the plate being made of materials like glass, wood, plastic, or metal.
Furthermore, the electronic apparatus can have multiple sound generating modules positioned strategically on the plate to correspond to different regions for a surround sound effect. The supporting frames include border portions and holes overlapping the vibration devices, while integration members can be used between the vibration devices and supporting frames. The sound generating modules may include woofers, and the apparatus can also include additional covers, partitions, and modularized elements to enhance sound quality and distribution. Overall, the patent details a sophisticated system for generating sound through vibration in a display apparatus, offering versatility in design and functionality for improved audiovisual experiences.
