New technology will allow for thinner,lighter devices

Kyocera Corporation today announced that it has developed an ultra-thin, lightweight audio device called Smart Sonic Sound. The new product is based on the company's history of fine ceramic technology implementations, and utilizes a piezoelectric actuator combined with a special film to create a piezo film speaker. The company says Smart Sonic Sound will contribute to making digital devices even thinner such as flat-screen TVs, PCs and tablets. It's low directivity characteristics broaden the sound projection range, providing 180-degree sound projection.

This piezo actuator audio technology is being utilized in a flat-screen television for the first time by LG Electronics in the company's new 55-inch curved-screen OLED TV. Smart Sonic Sound comes in three different sizes, and Kyocera plans to expand its use in a broad range of applications including digital devices and automotive applications with strict weight requirements.

Smart Sonic Receiver uses a ceramic actuator to send vibrations via tissue conduction and traditional air conduction through display screens without the need for a traditional earpiece or loudspeaker, making it ideal for clear audio in exceptionally noisy environments. The new Smart Sonic Sound technology uses the same base technology, but with a different implementation that amplifies air conduction.
