2. Low directivity, and high responsivity create a high-quality audio experience
As the new product's piezo actuator and film create sound through vibrations, the directivity (directional projection of sound waves) is more balanced than a conventional speaker, meaning that sound quality and volume are delivered almost completely equally within a 180 degree range. Moreover, the high speed of responsivity in the Smart Sonic Sound is able to reproduce delicate and minute sounds such as raindrops and background effects with greater clarity, thus providing an even more realistic audio experience.
3. No rare earth elements used
Electromagnetic speakers use the repulsion force of magnetic fields created between the magnet and coil to produce sound, which is achieved through the use of rare earth elements such as neodymium. Conversely, the core component in the Smart Sonic Sound is made of a piezo actuator (fine ceramics) and resins, so the new product eliminates the use of rare earths.
Kyocera will continue to develop new applications for the use of its piezo film speaker, helping to contribute to the further downsizing of electronic equipment.
Other products using Kyocera piezo actuators
Kyocera has developed a range of piezo actuator products using the company's proprietary technology. Among the wide range of applications, some notable examples include: actuators*2 for diesel-engine vehicles requiring high reliability; actuators*3 in the world's fastest inkjet printhead*4 used for on-demand printing applications; as well as Kyocera's Smart Sonic Receiver.

sound device for a flat-screen television. As of July 31, 2013; based on
research by Kyocera.
*2 These actuators control fuel injection, thus enhancing fuel efficiency and reducing emissions.
*3 These actuators are used to control the ejection of ink drops in inkjet printheads.
