PiezoListen™ Ultra-thin Piezo Speakers

TDK's PiezoListen ultra-thin piezo speakers balance design and functionality by allowing virtually any surface to be turned into a speaker. Unlike typical miniature speakers that tend to have a metallic sound, PiezoListen produces sound with dynamic range, volume, and richness (midrange and high-end) that easily fills a room or vehicle. Because PiezoListen can be attached directly to OLED, LCD, and back covers of display panels, sound emanates directly from the screen producing optimal sound localization.

Multilayered sheets of TDK's original PZT piezoelectric ceramic material are connected through via-hole to achieve an ultra-thin body while maintaining a high displacement and high SPL (sound pressure level). PiezoListen products are available in various sizes with dimensions as small as 20 mm x 10 mm x 0.7 mm, which is up to 65% reduction compared with conventional products. PiezoListen is available for use in a variety of applications including car audio and infotainment systems, televisions, PCs, tablets, and more.
