We supply piezoelectric and electromagnetic signal generators. Signal generators are divided into converters (for alternating voltage signals) and buzzers with their own oscillator (for direct current operation).Here, sound waves are generated in different ways.There are piezoelectric, electrodynamic and electromechanical designs.Some signal generators have an internal resonant circuit and only need an applied DC voltage to generate sound, while the others require external control.

This presentation serves only as a brief introduction to our products;we deliver and design professional acoustic components for your applications.We also welcome special O.E.M.Parts and designs from our customers that are not shown here.
