Microsoft thinks of all-screen phones and this patent shows how to fix the speaker problem

"

It is a trend in current mobile telephony and no, we are not talking about the notch or the eyebrow that the iPhone X has made fashionable. However, it is related, since the notch is a consequence of a design in which the frames are increasingly smaller and there is a need to continue housing some pieces of hardware ."

This is the case of the front camera and some sensors. The Essential Phone was the first to launch its proposal, but the most popular has been the one created by Apple on the iPhone X to solve problems with Face ID.Later, some Android manufacturers have joined the trend but without worrying about the lack of Android support for this type of screen. The fact is that not only the camera is affected, because where are the front speakers?

The display is the speaker

And we are not only talking about the speaker designed to listen to music, but about the necessary to make phone calls In this sense, what we have seen so far is the option that allows the screen to be used as a speaker, used in the Vivo Apex or in the Xiaomi Mi Mix (and Mi Mix 2) and its successor. A solution (similar to the one seen on the Sony A1 television) to which we can add the own variant created by Microsoft.

"

The American company has thought that the best thing is to use the screen as a speaker and for this reason it published a patent with a variant of what known up to now.En titled DISPLAY STRUCTURE HAVING VISUAL DISPLAY AND AN AUDIO OUTPUT dated September 2016."

A patent that seeks to avoid having to place the speakers on the sides or back of the mobile device, where they direct the sound away from a user and to avoid having to resort to this solution, they bet on using an OLED screen together with a piezoelectric layer (in mechanical communication with the deformable transparent surface layer) joined with glue and that is the one that vibrates to generate sound. They also claim that it could also be used to generate haptic feedback when a user touches the screen.

We don't know if this patent will ever come to fruition on the new innovative phones or devices you may already be thinking of developing in American company.
