Smart Sonic Sound: Ultra-Thin, Lightweight ‘Piezo Film Speaker’ for TVs, PCs, Tablets From Kyocera

Japan's Kyocera Corporation has developed an ultra-thin, lightweight  audio device, called “Smart Sonic Sound” which is the result of combining a piezoelectric actuator with a special resin film to produce a proprietary, piezo film speaker that is considerably thinner and lighter than conventional electromagnetic speakers, while also enhances audio quality for a much more realistic audio experience.

The Smart Sonic Sound already provides the audio for LG's 55-inch curved-screen OLED TV and the company hopes it will give designers of future TVs, computers and tablets more scope to place speakers on the front face of products, enabling an overall size reduction and expanding design options. Kyocera also plans to expand its use in a broad range of applications including digital devices and automotive applications with strict weight requirements.

Smart Sonic Sound comes in three different sizes (large, medium and small). The large speaker measures 70 x 110 x 1.5 mm, weighs 23g, and has a frequency range of 200 Hz to 20 kHz. The medium version measures 35 x 65 x 1.0 mm, weighs 7g, and has a frequency range of 500 Hz to 20 kHz. The smallest speaker measures a diminutive 19.6 x 27.5 x 0.7 mm, weighs just 1g, and outputs a frequency of 600 Hz to 20 kHz.

According to Kyocera, the directional projection of sound waves is more balanced than a traditional speaker as the piezo actuator and laminated film create sound through vibrations. The resultant sound quality and volume are delivered at almost equal levels within a 180 degree range creating a more precise audio representation. Kyocera says the Smart Sonic Sound is capable of reproducing “delicate and minute sounds such as raindrops and background effects, with greater clarity,” enhancing audio playback for a more true-to-life listening experience.

Smart Sonic Sound is the second audio innovation from Kyocera. The Smart Sonic Receiver was introduced by the company in 2012 for smartphones sold in Japan and North America. It 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.” The latest Smart Sonic Sound uses the same core technology but with “a different implementation that amplifies air conduction.”
