Working on a different principle than the regular electrodynamic speakers, piezo speakers use no coil and there is no electro-magnetic interference. With lower power consumption and a slim profile, they are most suitable to be installed in a flat and narrow space, such as portable devices.


  • With lower power consumption and a slim profile, piezo speakers are most suitable for portable devices with limited space or very thin thickness.


  • Low weight, low profile
  • High sound pressure level
  • No Electromagnetic interference
  • Low power consumption
  • Low heat generation

As a leading supplier of piezoceramics in Taiwan, Unictron provides piezoceramic elements that are perfect for piezoelectric speaker applications. Our engineering teams have more than 25 years of experience working in the piezo ceramic industry. With a sound background in materials formulations and ceramic processing technologies as well as advanced characterization and manufacturing facilities, we are able to develop and mass produce various sizes of piezoceramic elements for this application.
