PiezoListen™ Ultra-Thin Piezo Speakers

TDK PiezoListen™ Ultra-Thin Piezo Speakers transform virtually any surface into a speaker without compromising the existing structural design. These high-power actuators can be attached directly to OLED and LCD displays as well as on the back covers of display panels. This allows the sound to emanate directly from the screen to produce dynamic range, volume, and richness (midrange and high-end). PiezoListen speakers use multilayered sheets of TDK's PZT piezoelectric ceramic material, connected through a VIA hole, to achieve a low profile with high displacement and high sound pressure of 80dB. These devices are available in dimensions as small as 20mm x 10mm x 0.7mm with 34W maximum output power and 2Ω to 100Ω impedance.
