Sony has made the whole screen of an TV resonate to produce sound in what the company calls the world-first Acoustic Surface sound system. Aside from making the speakers "invisible," Sony says this approach also lets sound emanate directly from the screen itself, providing sound and image synchronization for the viewer, wherever they're sitting.
Getting the display, which is most likely an LG panel, to act as a speaker has necessitated the mounting of two actuators to the rear of the display, while all inputs have been relegated to a large rear-facing subwoofer that also serves as the TV's stand. Sony says that the vibrations of the screen won't be visible to the eye, even at high volumes.
