TDK Corporation has expanded its lineup of ultra-thin PiezoListen speakers with new types featuring a wider dynamic range and higher sound pressure level (SPL) in the low frequency range, even at voltages up to 24 V.
The PiezoListen series of piezo speakers now includes the PHUA6630 wide dynamic range speaker with an operating frequency range of 400 Hz to 20 kHz. This product has a footprint of 66 x 30 mm and complements the existing PHUA3030 speaker, which was introduced in May 2019.
Also new in the series are two new sound positioning speakers with an operating frequency range of 1000 Hz to 20 kHz. The miniature PHUA2010 features dimensions of just 20 x 10 mm, while the PHUA3015 speaker measures in at 30 x 15 mm. Samples are available for all types.
With a thickness as low as 0.49 mm the PiezoListen type PHUA3030 is the world’s thinnest speaker that is able to cover a wide frequency range from as low as 400 Hz up to 20 kHz.
PiezoListen can turn nearly any surface such as a display screen into a speaker. In addition, it is easy to integrate into existing applications without sound emission holes, enabling flexible acoustic solutions that require no changes to the exterior designs.
The development of the low-profile, high-displacement piezoelectric speakers was made possible by TDK’s patented multilayer and material technologies. As the evolution of video content rapidly moves to 4K and 8K resolutions, the demand for advanced multimedia will continue to grow. With PiezoListen TDK will enable completely new integrated acoustic solutions and thus contribute to the evolution of customer application design.
