The screen is a speaker


Popular Science - - BEST OF WHAT’S NEW 2017 -

Edge-to-edge screens are the hot look for high-end TVs, so room for a speaker grate is out of the ques­tion. Sony solved this de­sign prob­lem in its Bravia OLED A1E 4K HDR TV by em­bed­ding four ac­tu­a­tors be­hind the dis­play to cre­ate visu­ally im­per­cep­ti­ble vi­bra­tions—in other words, sound. The dis­tance be­tween ac­tu­a­tors can cre­ate lo­cal­ized au­dio, so sound can move across the dis­play to match the ac­tion.
