The development of new piezoelectric alarms does not only require electronics expertise but also requires the subtle clarification and investigation of various acoustic and physical properties!

A piezo signal alarm consists of electronics, which on the one hand contains a power supply and on the other hand a wave generator. A piezo ceramic disc, which is glued onto a brass disc is connected to the generator and acts as a speaker.

The micro-movements of this disc, depending on the frequency 2'750 or 3'250 vibrations per second, are compressing the air volume inside a Helmholtz resonator resulting in an acustic amplification thus generate the familiar sound!

A more detailed description can be found in the link under the link Funktionsprinzip_piezoelektronischer_Summer.pdf . (currently German only).
