Vibrating Elements
(Unimorph Equivalent)



Omega Piezo produces a wide range of vibrating elements (unimorph equivalents) for use in applications including: alarms, speakers, atomizers, mist generators, and many others. The geometry and characteristics of our standard sound elements are listed in the following table.

We also produce custom elements to precisely suit your application.
