Current smartphone downsizing trends have prompted Google to acquire Redux, a startup that offers display audio technology. Using the screen as speakers will increase the useful area of the display to almost the maximum possible value. The development of a joint venture project was agreed back in August 2017, and only in December did Redux decide to join the Google family. The cost of such an agreement was not disclosed. Startup Redux closed its website to prevent leaks into the network about further plans. Redux currently owns 178 patents for innovative technologies, including the main invention, called the “bending wave”. The reproduction of sound waves, as well as the transmission of a tactile reaction, is performed using drives that excite vibrations of the display surface. Sony used similar techniques in OLED TVs. Redux tech turns the screen into a speaker, and a haptic surface. Trying it out here. The sound is actually coming from the screen. pic.twitter.com/VPAi6TzKk9— Stan Schroeder (@franticnews) February 28, 2017 Using technology from Redux will replace the acoustic speakers in smartphones in the next two years. This solution requires less energy than the miniature speakers of traditional smartphones. In addition, eliminating additional openings in the housing will greatly increase protection against moisture and water.
