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 precisely tailored to your application.
