The last public communication from Redux was in April 2017, when it unveiled its Panel Audio technology, which uses haptic vibrations and "bending wave" sounds to turn smartphone and tablet screens into high-quality speakers. If replaced, that could leave more space for a larger battery or other components: even, perhaps, the return of the 3.5mm headphone jack, were Google so inclined.
The Bloomberg report says that the shares were transferred to Google on December 13.
Some lucky tech developer in Cambridge has achieved the cashing-out dream, with no less a cash bag than Google agreeing to buy the mad-sounding speaker technology created by Redux.
For Google, a company keen to prove itself in the world of hardware, the attraction of such tech is obvious.
In 2006 it acquired video-sharing platform behemoth Youtube for a deal exceeding $1.5 billion (£1.2 billion). The company had 178 granted patents, according to its LinkedIn page. The Verge was actually able to try out the startup's technology past year on a tablet. Redux is the developer of an innovative technology that allows surfaces, such as smartphone displays and PC monitors, to act as speakers. The sound quality is said to be "decent".
Mike Pettine is Packers' Defensive Coordinator
His defenses with the Jets were first, third, fifth, and eighth, and his Bills defense was 10th in his lone season in Buffalo. Pettine's scheme, like Ryan's, is rooted in a 3-4 system that relies heavily on press man cornerbacks and myriad blitzes.
The company now has 178 granted patents and more than 50 patents pending. Google might also use the acquisition to improve its future handsets' haptic feedback.
Redux raised $5m in March 2017 from investors including Arie Capital.
Alphabet has a range of potential uses for the technology.
According to Bloomberg, Redux was purchased via an Ireland-based subsidiary of Google at some point past year.
This appears to be the latest in a string of takeovers from the tech conglomerate. At the CES consumer electronics conference in Las Vegas this week, Google is heavily promoting its voice-controlled speakers that compete with Amazon.com Inc.'s Echo device.
