A patent published in the United States Patent & Trademark Office reveals that Motorola plans to create a floating lens displays for portable devices, which would also serve as a speaker sounds. With this, the gadget could play louder and less resonant, without having to devote more space to their structures (since the lens that functions as emitting sounds would be integrated into the device screen). This patent discloses the company's plans for their electronics to reproduce sounds louder and with less resonance, without any increase in power consumption.
Furthermore, using a piezoelectric ring structure involving this lens, the technology could play responses to taps made on the screen also know as haptic feedback. This feature also would require eight times less power than the methods currently used. As the technology is still a patent, there are no predictions of when it will reach commercial devices.
