According to filings, Google took control of the startup back in August and then subsequently shut down the company's website. Previous demonstrations show Redux playing back music via a tablet device, which possesses tiny actuators that vibrate the screen and effectively turn it into a loudspeaker. By eliminating the need for smartphone speakers, Google may be able free up more space for batteries and other important components inside future smartphones.
Although Redux has already integrated similar technology inside PCs and automotive infotainment systems, it has recently focused on bringing the same technology to mobile devices. In April 2017, the company told Engadget in a statement that it believed it would begin appearing in smartphones from 2018. Google's decision to buy the company may accelerate that rollout, meaning we could see Redux's haptic sound technology come to a Google device later this year.
