Piezoelectrics enable displays to provide both audio and touch feedback

The linked article is about the development of a technology that uses piezoelectric transducers to enable displays on mobile devices to provide both high-quality audio and touch feedback. Conventional speakers and haptic generators can be bulky, delicate and allow the entry of moisture or debris. Piezoelectric transducers will allow for mobile devices to be thinner, require less power as they consume little current, and produce sound and haptic feedback directly from the display panel. Furthermore, the sound and haptic feedback generated by piezoelectric transducers come from the front of the display, providing a more immersive experience. A chip using such technology is expected to be incorporated into mobile devices and laptops by the end of 2024.
