Kyocera piezoelectric film speaker delivers 180-degree sound to thin TVs and tablets
 

The thinner our devices become, the less room there is for speakers and other thicker components. Kyocera has a solution, however: it just modified its Smart Sonic Receiver conduction technology for use with conventional, over-the-air audio. The company's new Smart Sonic Sound device still relies on a piezoelectric actuator, but vibrates against a film to generate as much volume as a regular speaker in a far thinner (under 1.5mm thick) design. The new speaker might even sound better than its traditional counterparts. It delivers full volume and quality in a 180-degree listening arc, and it's responsive enough to recreate very subtle noises. Smart Sonic Sound is already shipping in LG's 55-inch curved OLED TV, and Kyocera expects it to reach laptops, tablets and other devices where interior space is valuable.
