DEVELOPMENT AND PRODUCTION IN SWITZERLAND
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!
