According to a new report from the Korean news outlet Sisa Journal, Samsung is collaborating with LG to create an innovative display technology that could change the way users answer calls on foldable devices. By replacing the traditional ear speaker, this groundbreaking approach aims to allow users to maintain their privacy while using their devices in a compact form.

This cutting-edge technology is rooted in piezoelectric technology, which harnesses vibrations to produce sound directly from the display itself. The advantage of this integration is significant—by embedding the sound-generating mechanism into the screen, there would be no need for an ear speaker, allowing for more efficient use of internal space. Users could simply place their ear on the outer screen to take calls discreetly while the phone remains folded.

Interestingly, while this technology is fresh for foldable devices, the concept of using piezoelectric sound generation isn’t entirely new. Xiaomi introduced a similar feature in its Mi Mix smartphone in 2016, which utilized a piezoelectric ceramic earpiece, enabling a near bezel-less design. Unfortunately, that innovation did not carry over into later models, which reverted to traditional audio solutions.

With Samsung and LG aiming to streamline the design of clamshell foldables, the removal of conventional ear speakers could enhance not just aesthetics but also functionality. This technology, still in development, has the potential to become a crucial feature of future foldable smartphones, providing users with enhanced privacy and innovative design.

As the smartphone market continues to evolve, developments like these indicate a shift towards more versatile and space-efficient designs. The integration of piezoelectric technology could not only redefine user interactions with foldable phones but also set new standards for the mobile devices of tomorrow. Stay tuned for more updates as we follow the progression of this exciting innovation!
