Piezoelectric Speakers

A piezoelectric speaker is a smart combination of a flexible sound supporting plastic diaphragm and a piezoceramic disc. This simple structured and lightweight component is capable of providing a wider frequency range than standard piezo sound generators and achieves aggressively loud Sound Pressure Levels (SPL). Combined with a clever designed housing, SPL over 110dB at 2m are possible. This performance makes the piezoelectric speaker the perfect choice for alarm and siren devices.
