"Our technology enables smartphone manufacturers to reclaim valuable space within phones, which could be filled by a bigger battery", Redux Chief Executive Nedko Ivanov said at the time. It also creates solutions to create so-called haptic feedback, which allows users to carry out different tasks on current smartphones by applying different pressure to the screen.
The system by Cambridge-based Redux could eliminate the need for small speakers to be used in mobile phones. In August, Google acquired the company for an undisclosed amount.
According to its page the company 'developed breakthrough technology which transforms the user experience by bringing surfaces to life with Sound and Touch'.
So far, Redux has only been able to use its technologies inside PCs and some vehicle infotainment systems - but that could be about to change.
If Google decides to use Redux's display-speaker technology on its future Pixel phones, the company could achieve a better bezel-less design without removing front-facing speakers.
Google has made a concerted effort at CES to promote new features in its series of voice-controlled speakers.
It is unclear what work the Redux team will do for Google, or already has been doing, but it's possible that they could be working to use the technology to improve the sound quality of Google's own smartphones. The Verge had some hands-on time with the company's tech previous year, trying out a tablet which vibrated its screen to function as a speaker, as well as a number of displays that used haptic feedback to mimic the feel of buttons, sliders, and dials.
Google has remained quiet on the acquisition of Redux.
